Candle Business Guides · Luxury Jar Candles
These two goals pull in opposite directions and the honest answer is a set of measurements, not a number. No supplier publishes a safe glass temperature for your candle, and any that did would be describing a candle they have never burned.
4 readings
per burn hour — pool width, pool depth, flame height and the heat of the glass — the measurements that replace a temperature figure nobody can give you · CSI live pricing, September 2026
Quick answers — read this first
How do I get a deep pool without overheating the glass? You cannot decide it from a catalogue. Pour the same candle with two or three wick candidates, burn each for four hours, and record four readings every hour. The wick that reaches the glass without making the jar uncomfortable to hold is the answer — and it is specific to your jar, wax and oil.What temperature is too hot for a candle jar? No CSI page publishes one, and this guide will not invent one. The only temperature several jar pages do state is a hot-pour limit of 85°C, which is a pouring instruction, not a burning limit. What replaces it is the hand test, taken at the same minute on every candidate.
The rule that overrides every other result: if the jar is too hot to pick up comfortably, or a flame climbs, or the glass sounds or looks stressed — put the candle out and abandon that configuration. An oversized wick or an unsafely hot jar is a hazard, and that candle does not ship.
What does the test cost? ₹159.55 of materials per 130 g candle with an Eco C1 wick, and ₹2,226.60 for a six-candle bracket across three wick types.
The short answer
Measure depth, not just width: most makers only watch whether the pool reaches the glass. Pool depth is the reading that separates a wick that is working from a wick that is running hot, and a steel ruler measures it in seconds.
Compare candidates, never absolutes: without a published safe temperature, the useful data is relative — this wick against that wick, in the same jar, at the same minute, in the same room.
Start below where you think you need to be: it is far easier to step up from a wick that leaves a narrow pool than to recover a batch poured on a wick that overheats the glass, because the second one is not a quality problem, it is a safety one.
In this guide
Sixteen cells per candidate, filled in by hand, in the same room, at the same minutes. That grid is what a wick decision actually looks like. Reading 2 is the one most makers skip and the one that separates a pool that is deep enough from a pool that is running away, and reading 4 is the one that can end a test at any hour regardless of how good the other three look.

Straight answer
How do I choose a wick that gives a deep melt pool without making the glass excessively hot?
By measuring, because the two halves of that sentence are the same variable pulled in opposite directions: everything that deepens the pool also puts more heat into the glass. There is no published figure to aim at — no CSI page states a safe glass temperature for a burning candle, and the only temperature several jar pages do give is a hot-pour limit of 85°C, which governs how you fill the jar and says nothing about how it behaves lit. So you buy a bracket and take four readings an hour. Build the test on a small jar where the effect is easy to see: the Shot Glass Jar at ₹288 states 6 cm diameter, 8 cm height and a 130 gram fill — a 28.27 cm² pool. Use Eco Soy CSI 400 at ₹399 a kilo, whose page states a melt point of 37.8°C, fragrance added at 80–90°C (85°C) with a two-minute stir, and a recommended wick of Eco Wicks — the only CSI wax page that names a wick at all. Add Palo Santo Fragrance Oil, stated up to 10% for soy wax with a flash point of 93°C and its own wick instruction: "Eco wicks or wooden wicks for an even, clean burn. Wick testing is recommended based on your container and wax type." At 8% of wax weight that is 120 g of wax and 9.6 g of oil. The bracket is short because the range is short: Eco Candle Wicks Thin (C1) at ₹5.90, Thick (C2) at ₹9.44, and Performance Wooden Wicks at ₹59 — two cotton sizes and one different construction, with no diameter stated on any of them. Pour six candles, burn two per candidate for four hours, and record pool width, pool depth, flame height and the heat of the glass every hour. ₹159.55 per candle, ₹2,226.60 for the whole bracket.
One line: deepen the pool one wick step at a time, measure the depth and the glass every hour, and stop the moment the jar stops being comfortable to hold — because that is a hazard, not a data point.
Running a wick bracket? Eco Candle Wicks Thin (C1) ₹59 for 10 and Thick (C2) ₹188.80 for 20, Performance Wooden Wicks ₹590 for 10, and Eco Soy CSI 400 at ₹399 a kilo — six test candles and enough wicks left for two more rounds.

Why melt-pool depth and jar heat are the same variable
There is no wick that makes a deeper pool without putting more heat somewhere. The only question is where the heat goes.
A wick is a fuel pump. It draws liquid wax up to the flame, and the flame returns heat to the wax around it. A bigger wick draws more fuel, burns a larger flame, and returns more heat — which melts more wax, faster, and deeper. Every desirable consequence of a bigger wick and every undesirable one come from the same mechanism. You cannot have the first without some of the second, and a supplier who implies otherwise is selling you a story.
Where that heat ends up is what you are actually choosing between. Some of it goes into melting wax — useful, because the pool is the surface fragrance leaves from. Some goes into the air above the candle — unavoidable. Some goes into the glass, and that is the part that decides whether the candle is safe to sell. The glass then does two things with it: it conducts heat outward to the surface a customer touches, and it stores it, so a jar that felt fine at the end of hour one can feel very different at the end of hour four. This is why a two-hour test is not a test.
Pool depth is the reading that makes this visible earlier than anything else. A wick that is one step too large often reaches the glass at a perfectly reasonable time — you would pass it on width alone — but it does so with a pool that is noticeably deeper than the smaller candidate managed, and that extra depth is stored heat sitting against the wall. Measure it. A steel ruler or a wooden skewer against the rim gives you millimetres, and millimetres are enough to rank two candidates unambiguously.
The mistake: treating "deep melt pool" as a target in its own right. Depth is not a virtue; it is a symptom. What a customer experiences is the surface of the pool — its area, its temperature and how quickly it forms — and a pool can be too deep in a way that is worse in every respect: more liquid wax sloshing when the jar is moved, more heat in the glass, more of the candle molten at once, and a wick that is being asked to stand up in a deeper column of liquid. Aim for a pool that reaches the glass cleanly and stays shallow enough to be stable. The related diagnosis when a pool is too small is in why does my candle tunnel even with the correct wick.
The four readings, and what each one is actually telling you
Every reading below is something you can take with a ruler, a phone timer and your own hand. None of them requires a laboratory, and none of them is a figure you will find on a product page. Take all four, every hour, on every candidate.
The four readings · what to record and what it means
How to take each reading, what a low result means, and what a high result means
| Reading | How to take it | Too low means | Too high means | Action |
|---|---|---|---|---|
| 1. Pool width | Ruler across the liquid surface, in cm, and note whether it touches the glass all the way round | Wick under-sized; a ledge of unmelted wax will build up at the rim | Cannot exceed the jar — but reaching the wall in the first hour is very fast | Step the wick up one size if the pool has not reached the glass by hour three |
| 2. Pool depth | Steel ruler or a skewer held vertically at the centre, read in mm from the solid wax below | The pool has barely formed; usually paired with a narrow width | Too much heat is going in; stored heat will show up in the glass by hour four | If depth grows faster than width, the wick is too large for the diameter |
| 3. Flame height | Ruler held beside the flame, in mm, plus a note on flicker, soot and mushrooming at the tip | Wick drowning, often from too much oil or a wick too small for the wax | A climbing or dancing flame, carbon build-up, smoke against the glass | A climbing flame ends the burn. Extinguish and drop a wick size |
| 4. Glass heat | Touch the wall at mid-height and the base with the back of a finger, then try to pick the jar up as a customer would | Nothing — a cool jar is never a problem | Uncomfortable, or the base is hot as well as the wall | Extinguish. That configuration is finished. |
Reading 4 is different in kind from the other three, and it is worth being explicit about why. Readings 1 to 3 produce scores you compare between candidates — this wick against that wick, this hour against that hour. Reading 4 produces a pass or a stop. There is no version of "slightly too hot to hold but it smells wonderful" that turns into a product. An oversized wick or an unsafely hot jar is a hazard, and a candle in that state does not go to a customer regardless of what the other fifteen cells in the grid say.
Take reading 4 on the base as well as the wall
Most makers check the side of the jar and stop there. The base matters more for the way a candle is actually used, because it sits on a customer's furniture for the whole burn and because a thick base stores heat differently from a thin wall. Touch both, at the same minute, on every candidate, and write both down. If the base is warming noticeably by hour three while the wall is fine, that is information about the jar's construction as much as about the wick — and it leads into what a heavy jar with a thick base does to a wick test.What CSI publishes about temperature — and what it does not
It is worth laying this out plainly, because the gap in the published information is exactly why this guide is a protocol rather than a recommendation. Here is every temperature figure relevant to this question that appears on a CSI page, and what each one actually governs.
Stated temperatures across the materials in this build
What each published figure governs, and what it does not
| Figure | Where it is stated | What it governs | What it does not govern |
|---|---|---|---|
| Melt point 100°F (37.8°C) | Eco Soy CSI 400 | The temperature at which the wax begins to melt | How hot the pool gets while burning, or how hot the glass gets |
| Fragrance add temperature 80 to 90 degrees; add at 85°C and stir 2 minutes | Eco Soy CSI 400 | When to add the oil during making | Anything about the burning candle |
| Safe for hot pour up to 85°C | Several jar pages, including the Clear Glass Jar with Golden Lid | The maximum temperature of wax you should pour into that glass | How hot the jar may safely become while lit — a different question entirely |
| Flashpoint: 93°C | Palo Santo Fragrance Oil | A handling, storage and transport classification for the oil in its bottle | When to add the oil, and anything about the candle in use |
| Trim the wick to 1/4 inch before every burn | Candle Wick Trimmer | Good practice that keeps flame height consistent between burns | Wick size, which trimming cannot fix |
| A safe glass temperature for a burning candle | Nowhere. No CSI page states one. | — | — |
The fourth row deserves a sentence of its own, because it is the most commonly misused number in candle making. A flash point is a property of the neat oil measured in a standard test; it is the basis on which the oil is classified for storage and transport. It is not an instruction about when to add the oil to your wax, and it tells you nothing about the burning candle. The add temperature comes from the wax page — for Eco Soy CSI 400 that is 80–90°C, with 85°C named and a two-minute stir specified. Palo Santo's 93°C is one of only eighteen specific measured values in the CSI fragrance range; thirty-two other pages carry only the shared "> 93°C (suitable for alcohol-based products)" threshold line, which is a classification statement rather than a measurement and should never be quoted as one.
Do not treat the 85°C hot-pour limit as a burning limit. Several CSI jar pages state that the glass is safe for a hot pour up to 85°C. That figure exists because pouring hot wax into cold glass is a thermal-shock event, and it is a manufacturing instruction. It is not a licence to burn the candle up to 85°C at the wall, and it is not a threshold you should be aiming at with a thermometer during a burn test. The only honest burn-time criterion is comparative and tactile: does this jar stay comfortable to hold for four hours, and does it stay more comfortable than the next candidate up? Anything else is a number borrowed from a different question.
The wick bracket for a 6 cm jar, and what each candidate costs
The bracket is short, and it is short for a reason worth stating: CSI lists two Eco cotton sizes — Thin (C1) and Thick (C2) — plus wooden wicks, and only two wick pages in the entire range state a diameter. Eco Candle Wicks Loose are "designed specifically for 2 inch diameters" — 5.08 cm, close to this jar's 6 cm — and Cotton Braided Wicks Ready Made are for "large-diameter candles exceeding 8 cm", which places them above this build rather than in it. The main Eco Candle Wicks page states no diameter at all.
The bracket for a 6 cm jar · 28.27 cm² of pool · CSI live pricing, September 2026
Each candidate, the published guidance behind it, its cost, and the failure to watch for
| Candidate | Published guidance | Per wick | Materials per 130 g candle | Watch for |
|---|---|---|---|---|
| Eco Candle Wicks · Thin (C1) | No diameter stated; Eco Soy CSI 400 names "Eco Wicks" as its recommended wick | ₹5.90 | ₹159.55 | Pool that never reaches the glass; a rim ledge by the third burn |
| Eco Candle Wicks · Thick (C2) | No diameter stated; the 10-wick pack is currently sold out, so 20 is the entry point | ₹9.44 | ₹163.09 | Depth growing faster than width; glass warming by hour four |
| Performance Wooden Wicks | No diameter stated; 10 wicks and tabs per pack; Palo Santo's page names wooden wicks as an option | ₹59 | ₹212.65 | A different burn character — judge it on its own grid, not against cotton |
| Eco Candle Wicks Loose | "Designed specifically for 2 inch diameters" — 5.08 cm, the closest published figure to this jar | Cut to length from ₹413 per 5 m | Depends on your cut | Sold by the metre, so wick height is yours to set consistently |
| Eco Braided Wicks | "The perfect solution for large diameter container jars" — no number; likely above this size | Cut to length from ₹472 per 5 m | Depends on your cut | Probably too large for 6 cm; useful as the upper bound of the bracket |
Priced above: materials per candle = wax + oil + jar + wick. Wax 120 g of Eco Soy CSI 400 at ₹0.399/g = ₹47.88. Oil 9.6 g of Palo Santo at the 100 gm rate of ₹6.018/g = ₹57.77. Jar ₹288 ÷ 6 = ₹48. Wicks: C1 ₹59 ÷ 10 = ₹5.90; C2 ₹188.80 ÷ 20 = ₹9.44; Performance Wooden ₹590 ÷ 10 = ₹59. Totals: C1 ₹159.55, C2 ₹163.09, wooden ₹212.65. Note that the Shot Glass Jar page carries a conflict — the title says "Pack of 6" and the body says "This pack of five offers great value" — so confirm the count before costing. At five jars the per-jar price is ₹57.60 and the C1 candle becomes ₹169.15.
Start low. Stepping up from a wick that leaves a narrow pool costs you one more batch and teaches you where the ceiling is; stepping down from a wick that overheats the glass costs you a batch you should never have poured and, if you have already sold any of it, a great deal more than that. The asymmetry is the whole argument for beginning at C1 in a 6 cm jar even if your instinct says C2.
The CSI principle
A candle that is too hot has failed, not scored badly. There is no total on the test sheet that overrides the hand on the glass.
Three of the four readings rank your candidates. The fourth can end the round at any hour. Build the habit of taking it last and obeying it first.
The material specification for a 130 g test candle
All load arithmetic here follows CSI's own wording: a percentage of total wax weight, with the finished-candle equivalent given alongside. The jar is deliberately small — a 6 cm diameter and a 130 g fill make the difference between two wick sizes obvious within the first hour, which is exactly what you want from a test format.

The wax · the only page that names a wick
Eco Soy CSI 400
The right wax for this test for one specific reason: it is the only CSI wax page that states a recommended wick — "Eco Wicks" — which means your bracket starts from the manufacturer's own pairing rather than from nothing. The page also states a melt point of 100°F (37.8°C), a fragrance add temperature of 80 to 90 degrees with 85°C named specifically, and a two-minute stir before pouring directly. What it does not state is a maximum fragrance load, so hold at 8% and treat that silence as a limit rather than a licence. Listed in 1 kg and 5 kg only.
| Size | Price | Per kg | 130g candles @ 8% |
|---|---|---|---|
| 1 kg | ₹399 | ₹399 | ≈8 |

The fragrance · a stated wick instruction and a measured flash point
Palo Santo Fragrance Oil
One of seven CSI fragrance pages carrying a wick recommendation, and it names exactly the two constructions in this bracket: "Eco wicks or wooden wicks for an even, clean burn. Wick testing is recommended based on your container and wax type." The page states a recommended fragrance load of up to 10% for soy wax and up to 6% for paraffin, a cure of 48–72 hours for soy, and a flash point of 93°C — a specific measured value, not the shared "> 93°C" threshold line that appears on thirty-two other pages. That flash point is a handling and transport property; the add temperature for this build comes from the Eco Soy CSI 400 page.

Shot Glass Jar (Pack of 6) 130 gram
A small, straight-sided glass whose page states height 8 cm, diameter 6 cm and a fill capacity of 130 gram — all three numbers a wick test needs, which is unusual in a range where only 18 of 78 containers state a numeric dimension. Straight sides matter here: the pool width you measure at hour one is measured against the same diameter you will measure at hour four, which removes one variable from the grid. One caution: the listing's title says "Pack of 6" while the body text says "This pack of five offers great value", so confirm the count on the product page before you divide ₹288 by anything.

The instruments · what makes the grid trustworthy
Pen Thermometer and Candle Wick Cutter
Two cheap tools that turn a burn into a record. The Pen Thermometer at ₹354 is what keeps the add temperature at the 85°C the wax page specifies, so every candidate in the bracket is made identically — a bracket poured at different temperatures is not a bracket. The Candle Wick Cutter at ₹177 gives you a repeatable trim before each burn, which matters because flame height is reading 3 and an untrimmed wick contaminates it. Trimming cannot fix a wick that is the wrong size — but an untrimmed wick can make a correctly sized one look wrong.

The six-candle burn protocol
Six candles: two each of three wick candidates, so every candidate is burned twice — once at day 7 and once at day 14. The second burn is not redundancy. It is how you find out whether a marginal result was the wick or an unfinished cure, which is the misdiagnosis that sends makers back to the wick shelf for no reason.
1
Pour six identical candles, one wick variableJars 1 and 2: Eco C1. Jars 3 and 4: Eco C2. Jars 5 and 6: Performance Wooden. Same 120 g of Eco Soy CSI 400, same 9.6 g of Palo Santo, same 85°C add temperature, same two-minute stir, same jar. Odd numbers burn at day 7, even numbers at day 14.
2
Draw the grid before you light anythingFour rows, four columns, one sheet per candle, with the candle number, wick, pour date and burn date at the top. Sixteen cells. If you are improvising the record while the candle burns you will miss hour three, which is when the interesting things start.
3
Trim to about 6 mm and lightTrim once, before the burn, and do not trim again mid-burn — mid-burn trimming resets reading 3 and makes the hours incomparable. Keep the room still, the door closed and the jar on a heat-tolerant surface away from anything flammable.
4
Fill in four cells on the hour, every hour, for four hoursPool width in cm and whether it has touched the glass all round; pool depth in mm at the centre; flame height in mm with a note on soot, flicker and mushrooming; and the glass by hand at the wall and at the base. Take the fourth reading last and write it down before you interpret it.
5
Stop the moment reading 4 failsIf the jar is uncomfortable to hold, if the base is hot, if a flame climbs or dances persistently, or if the glass shows or sounds any sign of stress — extinguish the candle and end that candidate. Write the hour it happened at. An oversized wick or an unsafely hot jar is a hazard, and that configuration does not go to a customer under any circumstances.
6
Choose the largest wick that passed all four hours, not the largest that looked goodRead the grids side by side. The winner is the candidate whose pool reached the glass with the shallowest depth and the calmest flame, and whose jar was still comfortable at hour four. If two candidates both pass, take the smaller one — you are building a product that will be burned by people who do not trim wicks.
The mistake: fixing a hot jar with a shorter burn instruction. It is tempting, when a candidate runs hot at hour four, to keep the wick and put "burn for no more than two hours at a time" on the label. Care instructions are good practice and candle care stickers are worth buying — but they are not a substitute for correct wick sizing, because a customer will burn the candle for as long as they like. If the configuration only passes when the burn is cut short, it has not passed. Drop a wick size and test again. The wider diagnosis when the flame itself is the problem is in candle flame too high: how to fix.

Two notes on the arithmetic. The wick lines together come to ₹837.80 — more than a third of the materials subtotal — and you will use six wicks out of forty. That looks wasteful and is not: the leftovers are rounds two and three, and the alternative is guessing. Second, Palo Santo's per-gram price is flat at ₹6.018 from the 100 gm pack up to 1 kg (₹601.80, ₹3,009 and ₹6,018), so there is nothing to gain by buying a bigger bottle for this test — the 15 gm pack at ₹106.20 works out at ₹7.08 per gram and covers barely one candle, and the 50 gm at ₹300.90 is ₹6.018 but leaves no margin for a second round.
Depth is a measurement. Heat in the glass is a decision. Only one of them is negotiable.

Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. The version of this page that sold the most wicks would name a temperature, name a wick and let you order. We have done neither, because the temperature does not exist on any page we could honestly cite and the wick depends on a jar, a wax and an oil we have not burned together. What we have given you instead is every temperature figure our pages do state, an explanation of what each one actually governs, and a grid you can fill in for any jar you own.
Every price, pack and specification here comes from live CSI stock in September 2026 and links to the product page, which is always authoritative. Wick guidance is quoted only where a page gives it: two wick pages in the range state a diameter, one wax page names a recommended wick, and seven fragrance pages carry a wick recommendation that ends in an instruction to test against your own container. Flash point is presented as the handling and transport property it is, never as an add temperature, and the "> 93°C" line that appears on thirty-two fragrance pages is not treated as a measurement. CSI publishes no burn-hour figure, no hot-throw measurement and no safe glass temperature for a burning candle, and none is used or implied here.

Frequently asked questions
How hot is too hot for a candle jar?
No CSI page publishes a safe glass temperature for a burning candle, and this guide will not invent one. The only temperature several jar pages state is a hot-pour limit of 85°C, which governs how you fill the glass, not how it behaves lit. Use the hand test instead, at the wall and the base, at the same minute on every candidate. If the jar is uncomfortable to pick up, the wick is too big and that candle does not ship — an oversized wick or an unsafely hot jar is a hazard, not a trade-off.
How deep should a melt pool be?
Depth is not a target — it is a symptom you measure to rank wick candidates. What you actually want is a pool that reaches the glass cleanly and stays shallow enough to be stable, because the fragrance leaves from the surface and the depth mostly represents heat stored against the wall. Measure it in millimetres at the centre with a steel ruler, every hour. If depth is growing faster than width between candidates, the larger wick is too large for the diameter.
Which wick should I test first in a 6 cm jar?
Start low. Eco Candle Wicks Thin (C1) at ₹5.90, then Thick (C2) at ₹9.44, then Performance Wooden Wicks at ₹59 as a different construction rather than a third size. The closest published figure in the range is Eco Candle Wicks Loose, "designed specifically for 2 inch diameters" — 5.08 cm. The asymmetry matters: stepping up from too small costs one batch, while stepping down from a wick that overheats the glass costs a batch you should never have poured.
Can I use the fragrance oil's flash point to judge how hot my candle runs?
No. A flash point is a property of the neat oil measured in a standard test, and it is the basis for storage and transport classification. It is not an add temperature and it tells you nothing about the burning candle. Palo Santo states 93°C, one of only eighteen specific measured values in the CSI fragrance range; thirty-two other pages carry only the shared "> 93°C (suitable for alcohol-based products)" line, which is a classification statement rather than a measurement. Your add temperature comes from the wax page.
Will a shorter burn instruction fix a jar that gets too hot?
No. Care instructions are good practice and candle care stickers are worth buying, but a customer will burn the candle for as long as they want to. If a configuration only passes when the burn is cut short, it has not passed. Drop a wick size and run the grid again. The same applies to trimming: trimming to about 6 mm before every burn keeps flame height consistent and is sound practice, but it cannot correct a wick that is the wrong size for the diameter.
What does a 130 g test candle cost to make?
₹159.55 of materials with an Eco C1 wick: ₹47.88 of Eco Soy CSI 400 (120 g at ₹0.399/g), ₹57.77 of Palo Santo (9.6 g at the 100 gm rate of ₹6.018/g), ₹48 for the jar and ₹5.90 for the wick. With C2 it is ₹163.09 and with a wooden wick ₹212.65. The six-candle bracket across all three candidates is ₹2,226.60 in materials, or ₹2,757.60 with a thermometer and a wick cutter you buy once.

Figures verified September 2026: Pool area for a 6 cm diameter = π × 3² = 28.27 cm². Container specifications as published: Shot Glass Jar (Pack of 6) 130gram "Fill Capacity - 130gram", "Height - 8cmDiameter - 6cm", ₹288 — the listing's title says Pack of 6 while the body says "This pack of five offers great value", so the per-jar figure is ₹48 at six and ₹57.60 at five; several CSI jar pages, including the Clear Glass Jar with Golden Lid (150 gram), state "Safe for hot pour up to 85°C", which is a pouring instruction and not a burning limit. CSI lists 78 jars and containers; 18 state a numeric dimension. Wax specifications as published: Eco Soy CSI 400 "Melt Point 100°F (37.8°C)", "Fragrance Add Temperature 80 to 90 degrees", "add your fragrance or essential oils at 85°C (185°F), stir gently for 2 minutes, and pour directly", "Recommended Wick Eco Wicks", no fragrance load stated, no pour temperature stated separately, ₹399 per 1 kg and ₹1,996 per 5 kg. Fragrance specifications as published: Palo Santo Fragrance Oil "Recommended Fragrance Load: Up to 10% for soy wax Up to 6% for paraffin wax", "Cure Time: 48–72 hours for soy wax", "Wick Recommendations: Eco wicks or wooden wicks for an even, clean burn. Wick testing is recommended based on your container and wax type", "Flashpoint: 93°C", ₹106.20 per 15 gm, ₹300.90 per 50 gm, ₹601.80 per 100 gm, ₹3,009 per 500 gm, ₹6,018 per 1 kg — per-gram ₹7.08 at 15 gm and a flat ₹6.018 from 50 gm upward. Eighteen CSI fragrance pages state a specific measured flash point and thirty-two carry only the shared "Flash point > 93°C (suitable for alcohol-based products)" line, which is a classification statement and not a measurement; flash point is never used here as an add temperature. Seven CSI fragrance pages carry a wick recommendation, each ending in an instruction to test wick size against the container. Wick specifications as published: Eco Candle Wicks Thin (C1) ₹59 per 10 and ₹590 per 100, Thick (C2) ₹188.80 per 20 and ₹944 per 100, with the C2 10-wick pack sold out and no diameter stated on the page — C1 and C2 appear only as Shopify variant names; Eco Candle Wicks Loose "designed specifically for 2 inch diameters", ₹413 per 5 metres; Eco Braided Wicks "the perfect solution for large diameter container jars" with no numeric diameter, ₹472 per 5 metres; Cotton Braided Wicks Ready Made "engineered for large-diameter candles exceeding 8 cm"; Performance Wooden Wicks ₹590 per 10, ₹2,360 per 50, ₹4,130 per 100, imported, 10 wicks and tabs per pack. Candle Wick Trimmer page states "Trim your wick to 1/4 inch before every burn for the best results!". Candle Wick Stickers 40 per sheet ₹100; Pen Thermometer ₹354; Candle Wick Cutter ₹177. Labelled planning assumptions: fragrance load calculated as 8% of total wax weight (130 g candle = 120 g wax + 9.6 g oil, equivalent to 7.41% of the finished candle); a 5% wastage allowance for spills and top-ups; a 14–21 day cure as standard practice for soy container candles, with one candle per candidate burned at day 7 and one at day 14; a four-hour burn window and a trim to about 6 mm before each burn, both chosen for comparability rather than quoted from any page. No CSI page states a safe glass temperature for a burning candle, a burn-hour figure or a hot-throw measurement, and none is used or implied here. Prices and availability change — the linked product pages are always authoritative.
