In cost order, and with the cheapest instrument in the workshop. Of the five candidate causes in that question, three are temperatures — the glass, the wax and the room — and one ₹354 pen thermometer measures all three. The wax sits at the far end of the ladder because it is the only rung that costs thousands and reopens five settled questions at once.
₹354
one pen thermometer, which settles three of the five named candidates · the whole eight-step process ladder costs at most ₹885 in instruments, while round one of a two-wax comparison starts at ₹4,136.60 · CSI live pricing, September 2026
Quick answers — read this first
What is actually happening? Wax contracts as it solidifies. Where it lets go of the glass, a thin layer of air sits between wax and wall, and that region reads dark because air and glass bend light differently from wax and glass. There is no liquid in a wet spot. On its own it is cosmetic.What is the diagnostic order? Record, then clean, then glass temperature, then pour temperature, then cooling, then load, then dye, then the jar's finish — and only then the wax. That order is cost order, and it is also roughly likelihood order for a candle that used to be fine.
Which single purchase does the most? A Pen Thermometer at ₹354. Glass temperature at the pour, wax temperature at the pour, and room temperature while cooling are three of the five candidates, and all three are the same instrument.
When is it the wax? When the record sheet shows your process genuinely held still — same cleaning, same glass temperature, same pour reading, same cooling position, same load, same dye — and the walls still differ. Then a two-candidate round in your own jar is ₹4,136.60, and 10 kg of the winner is ₹5,074 or ₹6,370.
The short answer
A differential, never a verdict: five candidates, each with an observation or a paired test that separates it from the others. Nothing on this page tells you what caused your gap — it tells you what to look at and in what order.
One variable, one pot, one day: every step below is a paired comparison out of a single melt — half the jars cleaned and half not, half warm glass and half room temperature, two pour readings, two cooling positions. Change two things and the result is unreadable.
Buy the thermometer before the wax: ₹354 covers three candidates. A wax round costs ₹4,136.60 and settles one — and it is the only step that forces a wick, load, cure and throw retest.
In this guide
Rungs 1 to 8 total ₹354 of instruments, and two of them reduce your cost per candle. Rung 9 is eleven to twelve times the whole ladder and is the only one that makes you prove your wick, load, cure and throw again. Most makers start at rung 9.

Straight answer
My clear-glass candles are patchy. How do I work through contraction, jar cleanliness, glass temperature, pour temperature and cooling before I replace a raw material?
Work the list in cost order, one variable at a time, out of a single melt. Begin by accepting that contraction is not a fault — soy occupies less space solid than liquid, so some gap is ordinary material behaviour and the question is only how much shows. Then test the four things you control. Jar cleanliness costs nothing: clean half the jars in one batch and leave half as they arrive, and compare. Glass temperature at the pour, wax temperature at the pour and room temperature while cooling are three measurements on one ₹354 Pen Thermometer — which is why that single purchase settles three of your five candidates. Cooling conditions cost nothing either: compare outer and centre jars in the same batch, change the spacing, change the surface, move the jars away from an air-conditioning draught. Only then reach for a material. A fragrance load step from 10% to 8% actually saves ₹8.47 a candle on a 150 g jar; removing a dye saves a line on the bill; moving a clear jar to the frosted version of the same jar is ₹0 per candle at ₹70.80 either way. The wax is the ninth rung, not the first: two candidates at six jars each in your own jar is ₹4,136.60 of materials, then ₹5,074 for 10 kg of CSI 464 or ₹6,370 for 10 kg of CSI 468, plus a wick round and a cure of at least 48 hours and ideally one to two weeks before anything ships.
One line: buy a ₹354 thermometer, run eight paired tests that cost nothing more, and only reach for a different wax when your own record sheet proves the process was holding still.
Start at rung three. Pen Thermometer ₹354 for glass, wax and room temperature; Candle Wick Stickers ₹100 for 40 so the wick is not a variable; Clear Glass Jar with Golden Lid ₹944 per 10 to keep clear monitors in every batch.

The five candidates and what separates them
A differential is not a list of suspects. It is a list of suspects each with the question that excludes it.
The five causes named in the question are not alternatives in a tidy sense — two or three can be contributing at once. What makes them workable is that each one leaves a different fingerprint, and each has an observation or a paired test that separates it from the others. Nothing below is a verdict about your candles; it is what to look at and what to do next.
The differential
Five candidates, the pattern each tends to leave, and how to exclude it
| Candidate | Pattern it tends to leave | The observation or paired test that separates it | Materials cost |
|---|---|---|---|
| Wax contraction — ordinary material behaviour | Scattered or broadly even across jars; appears as the jar comes to room temperature; often static after a few days | If every jar in a well-controlled batch shows a similar amount and it stops changing between day 1 and day 7, you are probably looking at normal contraction in clear glass | ₹0 — a photograph at 24 hours and at 7 days |
| Jar cleanliness or handling | Local and irregular; sometimes maps onto where the jar was gripped; varies jar to jar within one batch | One pot, one pour: half the jars cleaned and dried to a written procedure, half used exactly as they arrived, alternating down the row | ₹0 — the jars are ones you were pouring anyway |
| Glass temperature at the pour | Tends to show up seasonally or by where the jars were stored; can be worse on the jars nearest a cold wall or an air-conditioner | Measure the inner wall before pouring. Then one pot, two groups: room-temperature jars against jars warmed by a method you record, alternating | ₹354 — the pen thermometer |
| Pour temperature | Consistent across a whole batch and changes when you change the pour; often trades against the top surface | A three-step ladder inside whatever your wax page states — for example 72°C, 76°C, 80°C for a wax stated at 70–80°C — four jars each, same pot, poured in sequence | ₹0 more — the same thermometer |
| Cooling rate and position | Differs between outer and centre jars in one batch; one-sided where a draught hits; base-heavy on cold stone or metal | Pour twelve identical jars and vary only where they stand: centre and edge of the rack, 2 cm and 10 cm apart, wood and stone, in and out of the draught | ₹0 — plus the room temperature reading |
Three of those five rows are temperatures, and they are the three a workshop almost never measures: the glass before the pour, the wax at the pour, and the room while the jars cool. That is the whole case for the ₹354 purchase. A maker who can tell you "the glass was 27°C, the wax was 76°C, the room was 29°C and 31°C two hours later" has turned three of the five candidates from guesses into data. A maker who cannot has five open questions and will usually resolve them by buying wax.
The mistake: calling a gap "moisture" and chasing it with drying. The word wet spot does real damage here. Makers wash and oven-dry jars for weeks, buy desiccant, blame the monsoon, and change nothing — because there is no water in the gap. It is air left behind by wax that contracted away from the glass. Drying the jar thoroughly is still worth doing, and it belongs at rung two, but do it as part of a written cleaning procedure you can test, not as a cure for dampness that was never there. The mechanism is set out in dark patches with no liquid in the jar and the seasonal version in the monsoon question.
The nine rungs, in cost order
Here is the full ladder, including the four rungs that come after the five candidates and before the wax. Each row gives what you change, what the materials cost, how soon you can honestly read a verdict, and what else that change forces you to retest — because the retest load is the hidden half of the price.
The cost-ordered ladder · CSI live pricing, September 2026
Nine rungs, their materials cost, their verdict time and their retest load
| # | Change | Materials cost | Soonest honest verdict | Also forces you to retest |
|---|---|---|---|---|
| 1 | Record and photograph what you already pour, at fixed checkpoints | ₹0 | Two batches — you need a normal before you have an abnormal | Nothing |
| 2 | Jar cleaning and handling procedure, tested paired | ₹0 | 24 hours to 7 days | Nothing |
| 3 | Glass temperature at the pour, measured then varied | ₹354 thermometer | 24 hours to 7 days | Nothing, if the warming method is gentle and recorded |
| 4 | Pour temperature ladder inside the stated window | ₹0 more | 24 hours to 7 days for the wall; check the top in the same batch | The top surface, and one cured burn before you ship |
| 5 | Cooling position, spacing, surface and draught | ₹0 | 24 hours to 7 days | Nothing — but it may cost you bench space or batch time |
| 6 | Fragrance load step down, e.g. 10% to 8% | Saves ₹8.47 per 150 g candle | 14 days — throw needs a cure | Hot throw, and the wick if the step is large |
| 7 | Dye removed or lightened | ₹0 and one less line on the bill | 24 hours to 7 days | Nothing structural — but it is a product decision |
| 8 | Jar finish, same family — clear to frosted or matte | ₹354 to prove · ₹0 per candle | 24 hours for the gap; one batch | Appearance only; one cured burn for safety |
| 9 | Change the wax | ₹4,136.60 round one, then ₹5,074 or ₹6,370 for 10 kg | 14 days per candidate, in series | Wick, pour temperature, load ceiling, cure and throw |
Worked out above. Rung 6: on a 150 g candle, 10% of the finished candle is 135 g of wax and 15 g of oil; 8% is 138 g and 12 g. The 3 g of oil you drop is ₹10.27 at the British Rose 100 gm price of ₹3.422 a gram, and the 3 g of extra wax is ₹1.80 at ₹599/kg — a net saving of ₹8.47 a candle. Rung 8: the Clear Frosted and White Matte 200 ml jars both list at ₹354 per 5 and ₹708 per 10 — ₹70.80 either way — and both pages state the same 200 ml fill and 8 cm × 7 cm, so one pack of 5 proves it. Rung 9: a pack of 20 Clear Glass Jars with Golden Lid at ₹1,888 (12 poured, 8 spare) + 1 kg of CSI 464 at ₹507.40 + 1 kg of CSI 468 at ₹650 + two 100 gm oils at ₹684.40 + Eco Candle Wicks C1 20 at ₹118 and C2 20 at ₹188.80 + ₹100 of stickers = ₹4,136.60. Six jars per candidate uses 828 g of each kilo and 144 g of oil in total. That is 11.7 times the cost of the thermometer that settles three candidates.
On rung 3: measure before you warm
The useful half of rung three is the measurement, not the warming. Take the inner-wall temperature of a jar from your normal storage spot, at the moment you would normally pour — that number alone often explains a seasonal pattern, and it costs one reading. If you then want to warm the glass, be careful what you warm it with. The Hot Air Gun at ₹531 is excellent for re-flowing a rough top, but its own page says the temperature "can not be adjusted" and that it reaches "about 200°c/390°f within a few seconds" at a stated 5–6 cm working distance — so it is a spot tool, not a controlled preheater. Controlled, even warming wants an oven or warm water you can actually measure, and the method goes on the record sheet either way.Why cost order and not wax first
Everyone agrees in principle that you should check the cheap things first. In practice the wax gets changed first anyway, and it is worth understanding why, because the reasons are psychological rather than technical and knowing them is what lets you resist.
A wax change feels decisive. It is one purchase, it arrives in a bag, and it converts an uncomfortable uncertainty into an action. Cleaning procedures and cooling positions feel like admitting the problem is you. A wax change is also the only rung with a supplier on the other end of it, which means it is the only rung anybody advertises. And it has a seductive property: because it changes five variables at once, something will look different, and a change that looks different is easily read as a change that worked.
The technical reason to resist is in the last column of the ladder above. Rungs 1 to 8 force you to retest almost nothing — a pour-temperature change wants one cured burn, a load step wants a throw check — so each one is a short loop you can close in a week. Rung 9 reopens the wick, the pour window, the load ceiling, the cure and the throw simultaneously, and each of those needs a cure before it can be judged. That is why it costs 14 days per candidate rather than 24 hours, and why the candidates cannot be run in parallel if the published pour windows differ: CSI 468 states a pour of 58–60°C against a melting point of 50–53°C, while CSI 464 states 80–90°C. You cannot run both out of one pot on one afternoon.
What a wax change actually buys
The same ₹4,136.60, spent two ways
| Spend | What it settles | What it leaves open | Time to a verdict |
|---|---|---|---|
| ₹354 on a pen thermometer | Glass temperature, pour temperature and room temperature — three of five candidates | Cleanliness and cooling position, both of which cost ₹0 to test | One weekend |
| ₹885 on a thermometer and a hot air gun | The same three, plus a way to re-flow tops while you experiment with the pour | Nothing on the process side | Two weekends |
| ₹4,136.60 on a two-wax round | Whether a different wax behaves differently in your jar — one candidate | All five process candidates, which are still uncontrolled unless you also did rungs 1 to 5 | Two to three weeks per candidate |
| ₹5,074 or ₹6,370 on 10 kg | Nothing on its own — it is the commitment, not the test | Everything, if the round above was not run properly | — |
Don't run a wax comparison on an uncontrolled process. This is the expensive version of the same error. If your cleaning, glass temperature, pour reading and cooling positions are not yet held still, a two-wax round compares two waxes plus all the noise — and noise in this system is large enough to reverse a result. Rungs 1 to 5 are not a detour before the real test; they are what makes the real test mean anything. Pour your current wax alongside the candidates as a control, and if the control jars look unusual, stop: you are qualifying waxes against a moving baseline. The full comparison discipline is in what to record when comparing waxes.
The three instruments that do the work
Rungs 1 to 8 need no new raw materials at all. They need three instruments, in this order of importance, and all three keep earning long after the diagnostic is finished. Each card shows every listed option.

Rungs 3, 4 and 5 · three candidates, one tool
Pen Thermometer For Candle Making
The whole argument of this guide in one purchase. Three of the five named candidates are temperatures — the glass before the pour, the wax at the pour, the room while the jars cool — and this measures all three. It also makes the published windows usable instead of decorative: Luxury Soy Wax Chunks state a pour of 70–80°C and 75–80°C in their own details table, CSI 464 states 80–90°C and CSI 468 states 58–60°C, which is a two-degree window nobody hits by feel. Record the reading you saw, not the window you aimed at — "76°C" is data, "70–80°C" is a plan.

Rung 4's companion · fixing tops while you move the pour
Hot Air Gun
Rung four has a catch: a hotter pour can help the wall and hurt the top, so a pour-temperature ladder tends to produce a few jars with rough or cratered surfaces that are otherwise perfectly good evidence. A heat gun lets you re-flow those tops after you have photographed the wall, so a ladder costs you data rather than stock. Read its page honestly before you plan anything else with it: it states that the temperature "can not be adjusted" and reaches "about 200°c/390°f within a few seconds", with a working method of "5-6cm distance" at "about a 45 Degree angle". That makes it a finishing and spot tool, not a controlled glass preheater. One CSI customer, Niharika S, has been "using this for the past 3 years".

Rung 4 at scale · holding a narrow window
Mini Electric Wax Melter (1 litre capacity)
The optional one, and only worth it if your diagnostic points at pour temperature and your wax has a narrow window. Double-boiling and chasing a falling pot is the commonest reason a recorded pour temperature is not the temperature that reached the last jar in the row — and a gradient down a row is exactly the kind of noise that reverses a comparison. The page states a 1 litre capacity, dual 300 W and 600 W power modes, an integrated leak-proof stainless steel liner and a one-year warranty. One CSI buyer, Tanya Walia, writes that "It has made my candle making journey so much easier", and another, Arzoo Vyas, describes a cold region where "my temperature would drop within seconds".

₹2,360 · buy it when rung 4 is your answer, not before Buy the melter
Priced above: Pen Thermometer ₹354 · Hot Air Gun ₹531 · Mini Electric Wax Melter ₹2,360. Rungs 1 to 8 need the first of those three and nothing else: ₹354, or ₹885 with the heat gun. Supporting items you may already own: Candle Wick Stickers ₹100 for 40 (₹2.50 a jar) so a leaning wick is not mistaken for a gap, Candle Making Weighing Scale ₹354 because a load step at rung 6 is a weight, and Bamboo Stirring Sticks ₹118 for 5 so the stirrer is the same every time. Bulk equipment orders are quoted on WhatsApp.
The CSI principle
Spend on the instrument that eliminates candidates, not on the material that replaces them.
₹354 removes three of five possible causes from your list. ₹4,136.60 tests one, and only tells you anything if the other four were already held still. The ladder is not about being frugal — it is about buying information in the order that makes the next purchase smarter.
Two weekends, eight rungs
Rungs 1 to 8 fit into two weekends of pouring and the weekdays in between, assuming you are pouring jars you would have poured anyway. The sequence below keeps every comparison paired out of a single pot, and keeps the clear jars that are your instrument in every batch.
1
Weekend one, before melting: set up the record and the monitorMark the base of every jar so photographs have a fixed orientation. Write the four checkpoint times on the sheet now — within an hour, at 24 hours, at 7 days, and after one temperature cycle you choose and describe. Take the inner-wall temperature of a jar straight from storage with the ₹354 thermometer and write it down; that single number often explains a seasonal pattern before you have poured anything.
2
Weekend one, batch A: cleanliness and glass temperature, pairedTwelve jars from one pot. Jars 1, 3, 5, 7, 9, 11 cleaned and dried to a written procedure; jars 2, 4, 6, 8, 10, 12 used exactly as they arrived. Within each group, half warmed by a recorded method and half at room temperature, with the actual inner-wall reading for each. Pour alternately down the row so no group gets the hot or the cool end of the pot. One pot, two variables that do not interact, and all twelve jars in one cooling row.
3
Weekday: photograph batch A at 24 hours, then leave it aloneTwo shots per jar, white card and black card, fixed distance and light, mark facing the camera. Then the gap map in clock positions and height bands, and one word for what changed. Ninety seconds a jar. Do not move the jars, do not polish the glass, and do not form a verdict yet — the 7-day checkpoint is where a static result separates from a growing one.
4
Weekend two, batch B: a pour-temperature ladder and a cooling gridTwelve jars, one pot, three pour readings four jars apart — for a wax stated at 70–80°C, something like 72°C, 76°C and 80°C, all inside the window and none above your jar's own hot-pour ceiling where it states one (the Clear Glass Jar with Golden Lid states 85°C). Then split each group of four by cooling: two in the centre of the rack and two at the edge, or two on wood and two on stone. Record the room temperature at the pour and at two hours. Keep the heat gun nearby for tops you want to tidy after photographing.
5
Weekdays: the cheap material rungs, one at a timeIf batches A and B have not explained it, run rung 6 as a single batch at a load one or two percentage points lower — which saves ₹8.47 a candle on a 150 g jar and needs a 14-day cure before you judge the throw — and rung 7 as a batch with the dye left out. Both are single-variable batches, and both reduce your cost per candle if they work. An unscented, undyed control jar in each batch is the cleanest evidence there is that the oil or the colour is involved at the wall.
6
Decide: rung 8, rung 9, or nothing at allLay the day-7 photographs from both batches side by side. If one group is clearly better, you have your answer and it cost ₹354. If everything looks similar and acceptable at the distance a customer will use, the honest answer may be that nothing is wrong. If everything looks similar and none of it is acceptable, choose between rung 8 — ₹354 to prove a frosted finish and ₹0 a candle thereafter — and rung 9, the ₹4,136.60 wax round, knowing that your process is now controlled enough for the round to mean something.
When the evidence really does point at the wax
The ladder is not an argument that the wax is never the answer. It is an argument about order. Four situations genuinely promote rung nine, and recognising them saves you from working the cheap rungs forever.
Stop rules
Four findings that promote the wax to the top of the list
| Finding | Why it points at the wax | What to do |
|---|---|---|
| Rungs 1 to 5 are all controlled and recorded, and the walls still will not come right | You have eliminated cleanliness, glass temperature, pour temperature and cooling as explanations | Run the two-candidate round properly, with your current wax as the control |
| A new lot of the same wax behaves differently from the last, with nothing else changed | The one variable that moved is the lot — and your record sheet proves the rest held still | Message the supplier with your records before buying a different wax; lot questions are a WhatsApp conversation |
| Your wax publishes no pour window and a ladder across a wide range changes nothing | You have searched the lever and the lever is not there | Shortlist waxes that publish a window, so your next test has a stated target to work to |
| You need a property the wax must supply, such as a higher load for throw plus a clean wall | Load ceilings are a wax property: CSI 464 states up to 10% and CSI 468 up to 13% | Choose on the published ceiling, then qualify the wall in your own jar |
One last thing that belongs in every version of this diagnostic. Everything above treats the gap as a commercial appearance standard you set, because that is what it is. What it is not is a safety question, and the safety questions are not negotiable and do not wait for the ladder: cracked or chipped glass, a wick that has drifted against the wall, a wick that clogs or flares, or a jar too hot to hold comfortably. Those candles do not ship whatever the wall looks like, and no amount of frosted glass or new wax makes them shippable. Keep that line separate and absolute, and the rest of this is a cost-optimisation problem you can actually enjoy.
Three of your five suspects are temperatures. One thermometer arrests all three for ₹354. The wax costs eleven times as much to question and answers only for itself.

Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles, and does not manufacture wax. Rung nine is the rung we sell. This page puts it last, tells you that the eight rungs above it cost ₹354 of instruments in total, and points out that two of them reduce your cost per candle. We would rather sell you a thermometer and keep a customer whose candles look right than sell you ten kilos of a wax that was never the problem.
Every price and specification comes from live CSI stock in September 2026 and links to the product page, where current pricing always takes precedence. Equipment descriptions, including the hot air gun's stated non-adjustable temperature and the melter's stated power modes, are the product pages' own wording. Stated wax temperatures and fragrance loads are quoted only where a page gives them, and they are formulation guidance rather than regulatory limits. No CSI page publishes a wax contraction rate, an adhesion score, a threshold temperature at which a gap forms, an acceptable-defect percentage, or any conversion from a temperature cycle to real shelf time, and nothing here invents them. The differential is written as observations to make and paired tests to run, not as a diagnosis of your candles — "could" and "check" are deliberate.

Frequently asked questions
What should I check first when my candles develop wet spots?
Check in this order: record and photograph what you already pour, then jar cleaning and handling, then glass temperature at the pour, then pour temperature, then cooling position and room temperature. The first two cost nothing; the next three need one ₹354 pen thermometer between them. Only after those come fragrance load, dye, the jar's finish and — last — the wax. That is cost order, and for a candle that used to be fine it is roughly likelihood order too.
Are wet spots caused by moisture in the jar?
No. The gap is air, left behind where the wax contracted away from the glass as it solidified, and it looks dark because air and glass bend light differently from wax and glass. Drying your jars properly is still part of a good cleaning procedure at rung two, but it is not a cure for dampness that was never there. On its own a gap is cosmetic — it does not make the candle unsafe and does not change how it burns.
How do I test whether jar cleanliness is the cause?
Pair it inside one batch. From a single pot, clean and dry half the jars to a written procedure and use the other half exactly as they arrived, pouring alternately so neither group gets the hotter or the cooler end of the pot. Same wax, same load, same wick, same cooling row. Photograph both groups at the same checkpoints. It costs ₹0 in extra materials because they are jars you were pouring anyway, and it is the only way to separate cleaning from everything else.
Should I raise my pour temperature to improve adhesion?
Test a ladder rather than make a single jump, and stay inside what your wax page states — CSI 464 says 80–90°C, Luxury Soy Wax Chunks say 70–80°C (75–80°C in their own details table) and CSI 468 says 58–60°C. Three readings, four jars each, one pot. Judge the wall and the top together, because a hotter pour can help one and hurt the other, and never exceed your jar's own stated hot-pour limit where it publishes one, such as the 85°C on the Clear Glass Jar with Golden Lid.
How much does it cost to replace my wax instead?
Round one of a two-candidate comparison in your own 150 g clear jar is ₹4,136.60: ₹1,888 for a pack of 20 jars, ₹507.40 and ₹650 for a kilo each of CSI 464 and CSI 468, ₹684.40 for two 100 gm oils, ₹306.80 for two wick sizes and ₹100 of stickers. Then a wick round, a cure of at least 48 hours and ideally one to two weeks, and ₹5,074 or ₹6,370 for 10 kg of the winner. That is 11.7 times the thermometer that settles three of your five candidates.
What if nothing I change makes any difference?
Then consider that you may be looking at ordinary contraction in clear glass, which is normal material behaviour and not a fault. Put one of your candles on a shelf at a metre, in the lighting a customer will actually use, and look once the way you would look at a stranger's product — makers inspect at 20 cm under a workshop light. If it still fails your standard, the two honest moves are a frosted or matte version of the same jar at ₹70.80, the same price as the clear one, or a wax round now that your process is controlled enough to make one meaningful.
₹354 before ₹4,136.60
Nine rungs. Eight of them cost one thermometer. Climb from the bottom.
Pen Thermometer ₹354 for glass, wax and room temperature. Hot Air Gun ₹531 for tops while you ladder the pour — its page states a non-adjustable temperature reaching about 200°C, so a finishing tool, not a preheater. Mini Electric Wax Melter ₹2,360 with stated 1 litre capacity and 300 W and 600 W modes, for holding a narrow window. Candle Wick Stickers ₹100 for 40. Clear Glass Jar with Golden Lid ₹944 per 10 to keep clear monitors in every batch. And when you reach rung nine honestly: CSI 464 ₹507.40 a kilo, CSI 468 ₹650 a kilo, with bulk pricing, GST invoicing and documentation on WhatsApp.

Figures verified September 2026: Pen Thermometer For Candle Making ₹354. Hot Air Gun ₹531 — page states "The heat gun's temperature can not be adjusted, but it can reach at about 200°c/390°f within a few seconds", a working method of "keep 5-6cm distance" at "about a 45 Degree angle", an ABS plastic exterior with stainless steel inside, a size of "about 9 in x 1.7in" and a 39-in wire. Mini Electric Wax Melter (1 litre capacity) ₹2,360 — page states a 1 litre capacity, "dual power modes (300W and 600W)", an "integrated leak-proof stainless steel liner" and a 1-year warranty. Candle Making Weighing Scale ₹354. Candle Wick Stickers ₹100 for 1 sheet of 40 = ₹2.50 each (the 100-sticker sheet at ₹236 is listed but sold out). Bamboo Stirring Sticks ₹118 per 5 = ₹23.60 each. Jars: Clear Glass Jar with Golden Lid (150 gram) ₹944 per 10 and ₹1,888 per 20 = ₹94.40 each, stating "150g fill capacity", "Height 8cm, outer diameter 7cm", base diameter approximately 6.5 cm and "Safe for hot pour up to 85°C"; Clear Frosted Glass Jar and White Matte Glass Jar ₹354 per 5 and ₹708 per 10 = ₹70.80 each, both stating "fill weight of 200 ml" and "Height 8 cm width 7 cm" — capacity in millilitres is not a gram fill, so weigh a filled jar. Wax: Luxury Soy Wax Chunks 1 kg ₹599 — stated "Recommended fragrance load: 8% to 13% of total wax weight", "10% Recommended", add at 80–90°C, "Pour at 70-80°C" with "Recommended pour temp 75-80°C" in the same page's details table, cure "a minimum of 48 hours (ideally 1-2 weeks) before performing burn tests"; Luxury Soy Wax CSI 464 1 kg ₹507.40 and 10 kg ₹5,074 — stated "Fragrance Load Up to 10%", "Melting Point 80°C – 90°C", "Pour Temperature 80°C – 90°C"; Premium Coconut Soy CSI 468 1 kg ₹650 and 10 kg ₹6,370 — stated "Fragrance Load Up to 13%", "Melting Point 50°C – 53°C", "Pour Temperature 58°C – 60°C". Eco Candle Wicks Thin (C1) 20 ₹118 = ₹5.90 each, Thick (C2) 20 ₹188.80 = ₹9.44 each. British Rose Fragrance Oil 100 gm ₹342.20 = ₹3.422 per gram. Maths assumptions, labelled: load is calculated as a percentage of the finished candle, so a 150 g candle is 138 g wax + 12 g oil at 8% and 135 g + 15 g at 10%; the Luxury Soy Wax Chunks page phrases its range as a percentage "of total wax weight", the other common convention. Rung 6 saving: 3 g less oil at ₹3.422 = ₹10.27, minus 3 g more wax at ₹0.599 = ₹1.80, net ₹8.47 per candle. Rung 9 round one: ₹1,888 + ₹507.40 + ₹650 + ₹684.40 + ₹118 + ₹188.80 + ₹100 = ₹4,136.60, covering 12 poured jars (6 per candidate, 828 g of wax each and 144 g of oil in total) with 8 spare jars; ₹4,136.60 ÷ ₹354 = 11.7. Ladder total for rungs 1 to 8: ₹354, or ₹885 including the hot air gun. A planning allowance of 3–5% on wax for spills and top-ups is a planning figure, not a specification. Not published anywhere in the CSI range and therefore never stated here: any wax contraction rate or percentage, any adhesion score or scale, any threshold temperature at which a gap forms, any acceptable-defect percentage, and any conversion from a temperature cycle to real shelf time — every temperature and duration in the fourth checkpoint is the reader's own choice. Prices and availability change — the linked product pages are always authoritative.
