An overheated candle rarely smells of nothing. It smells of the bottom half of the blend, which is a different and more expensive problem.

Candle Business Guides · Temperature & Incorporation
You lose the lightest, most volatile part of the blend to the air, and you keep the heavy part — so the candle does not go silent, it goes lopsided. Here is what actually changes above your wax's stated band, what does not change despite what you have read, and how to prove it on eight jars.
90°C
the top of the only fragrance add band published in the CSI wax range — Luxury Soy Wax Chunks at "80-90°C" and Eco Soy CSI 400 at "80 to 90 degrees" · above it you are in unstated territory · CSI live pricing and stated specifications, September 2026
Quick answers — read this first
What does "too hot" mean? Above the band your wax page states. On Luxury Soy Wax Chunks that is above "Recommended fragrance add temp 80-90°C"; on Eco Soy CSI 400, above its stated "80 to 90 degrees". There is no universal temperature — the wax defines it.What do I actually lose? The lightest materials in the blend. The Citrus Lemon page puts it plainly: citrus oils are "notorious for fading in candles faster than warmer fragrance families - the volatile top notes evaporate quickly in heat". Base notes are far less exposed.
Does the fragrance "burn off"? Not in the sense usually meant. Nothing ignites in a pot at these temperatures, and the oil does not chemically vanish — the light fraction evaporates and leaves the vessel as vapour. That distinction matters and is handled in full in can fragrance oil burn off in hot wax.
Can I fix an overheated batch? Not by reheating it. What left has left. You can re-melt and re-pour to fix appearance, and you can re-dose only if you are prepared to weigh and record it — then judge the result after a full cure, not the same evening.
The short answer
The loss is selective, not total: heat takes the volatile top of the pyramid first. That is why an overheated candle reads flat, muddy or "not like the bottle" rather than unscented — the base survived and the opening did not.
Time above the band matters as much as the peak: thirty seconds at 95°C and four minutes at 95°C are not the same event. Kill the heat early, add inside the band, stir, and pour.
Prove it before you rewrite your recipe: two temperatures, four jars each, scored blind after a full cure. Eight jars in 120 g glass cost about ₹1,430 and settle the question for your wax.
In this guide
Overheating does not scale a candle down evenly. It removes the top of the structure and leaves the bottom, so the finished candle has a different shape as well as less presence — and a top-heavy citrus or fresh blend has proportionally more to lose than a woody or gourmand one.

Straight answer
What happens if you add fragrance oil to wax that is too hot?
The lightest materials in the blend evaporate before the wax sets, and you are left with a candle built on whatever was heavy enough to stay. "Too hot" means above the band your wax page states — above "Recommended fragrance add temp 80-90°C" on Luxury Soy Wax Chunks, or above the "80 to 90 degrees" stated on Eco Soy CSI 400. A fragrance oil is a blend of many materials with very different volatilities, which is why perfumery describes it as a pyramid at all, and heat acts on that pyramid from the top down. CSI's own Citrus Lemon page states the mechanism directly: citrus oils are "notorious for fading in candles faster than warmer fragrance families - the volatile top notes evaporate quickly in heat". So the symptom is not silence. It is a candle that smells duller, heavier and less like the bottle, with the sparkle at the front missing — and that is much harder to diagnose than a candle that smells of nothing, because nothing is obviously broken. Two secondary effects follow. The hotter you start, the longer the blend sits in the volatile zone before the wax thickens, so time above the band compounds the peak. And a melt that overshot has further to fall to the stated pour window, which invites the surface problems set out in the pouring temperature guide. None of this is recoverable by reheating. What left has left; all you can do is measure the difference and then stop making it.
One line: too hot does not mute a candle, it decapitates it — the top notes go, the base stays, and the result is a blend you did not buy.
The cheapest fix is the boring one. A Pen Thermometer at ₹354 tells you where you are; a melter that holds a set temperature stops the overshoot happening — the 1 litre Mini Electric Wax Melter is ₹2,360. CSI customer Sonal Sahani writes of the larger imported unit: "I do not have to worry about temperatures at all, since the temperature knob does everything for me."

What counts as too hot, and it is not the same number twice
There is no temperature at which fragrance oil is universally "too hot". There is only the figure your wax published, and the space above it.
Most of the confusion in this topic comes from arguing about an absolute number. The usable definition is relative: too hot is above the band stated on the page of the wax you bought. Two CSI waxes publish that band, two publish only melt and pour temperatures, and one of those two works 20–30°C lower than the rest — so a single figure could not possibly serve all of them.
Stated figures per wax · quoted from CSI product pages, September 2026
Where the ceiling is, wax by wax, and what lies above it
| Wax | Stated add temperature | So "too hot" means | Stated pour temperature |
|---|---|---|---|
| Luxury Soy Wax Chunks | "Recommended fragrance add temp 80-90°C" | Above 90°C | "Recommended pour temp 75-80°C" and "Pour at 70-80°C" |
| Eco Soy CSI 400 | "at 85°C (185°F), stir gently for 2 minutes" · "Fragrance Add Temperature 80 to 90 degrees" | Above 90°C | Not stated — pour directly after adding |
| Luxury Soy Wax CSI 464 | Not stated | Unpublished — ask CSI, do not borrow a figure | "Pour Temperature 80°C – 90°C" |
| Premium Coconut Soy CSI 468 | Not stated | Unpublished, and its whole range is far lower | "Pour Temperature 58°C – 60°C" · melt "50°C – 53°C" |
The commonest way makers get too hot without meaning to. Not by aiming high, but by reading the target and then leaving the heat on. Wax keeps climbing for a while after you take the pot off, and on a small direct-heat melt it can gain several degrees. The fix costs nothing: kill the heat a few degrees below your chosen point, stir once, and let the melt coast into the band. The second commonest cause is a probe touching the vessel, which reads the metal rather than the wax and flatters you into thinking you are hotter than you are — then you correct downwards and end up genuinely too hot on the next batch. Measuring properly is covered in at what temperature fragrance oil should be added.
The four things that actually change
Ranked by how reliably a maker will notice them. Note that only the first is about fragrance; the other three are about the batch, and they are the ones most likely to make you blame the oil.
Above the stated band · mechanism, symptom, and what it costs
Four effects, in the order you will meet them
| # | What changes | Mechanism | How it shows up |
|---|---|---|---|
| 1 | The top of the blend thins | The lightest materials have the highest vapour pressure and leave the open surface first | Cold throw reads heavier and less bright; the candle is "not like the bottle" |
| 2 | Time above the band compounds it | Loss is a rate, so the longer the blend sits hot and uncovered, the more goes | Two batches at the same peak reading smell different because one was rushed and one was not |
| 3 | The pour window moves further away | An overshot melt has more degrees to lose before the stated pour band, so it sits longer | Surface finish, adhesion and wet spots — often misread as a jar or wax fault |
| 4 | Colour and appearance shift | Dyes and vanillin-bearing materials respond to heat and to time at heat | Deeper or duller colour than the last batch at the same dose; yellowing in white wax |
Effect 2 is the one worth internalising, because it explains the single most frustrating experience in this whole topic: two batches logged at the same temperature that do not smell the same. Temperature is a reading at an instant; loss is an integral over time. If you added at 92°C and poured within ninety seconds, and your next batch added at 92°C and sat for six minutes while you hunted for wicks, those are different processes. This is why the log sheet in this cluster records both the reading and the stirring duration — the pair describes the event, and neither number alone does.
What this page is not claiming
No figure here is a measurement of how much fragrance is lost at a given temperature — nobody has run that test for your oil in your wax, and this page does not pretend otherwise. What it offers is the mechanism, the wording CSI product pages publish, and a protocol you can run at your own bench. Where a sentence says "usually" or "typically", read it as standard practice in candle making rather than a measured result. For a specific oil's SDS or IFRA documentation, message CSI on WhatsApp at +91 7397976926; documentation is supplied on request.What does not happen
Three things get said about overheated fragrance oil that are worth putting aside, because believing them leads to the wrong corrective action.
It does not ignite in the pot. A stated flash point is a measured handling and transport classification — the lowest temperature at which a liquid gives off enough vapour to form an ignitable mixture with air under a defined test. It describes conditions for ignition in the presence of an ignition source, and it is not a temperature at which fragrance spontaneously catches. Of the 18 CSI oil pages that publish a measured value, most state figures between 185°C and 206°C — Sandalwood "Flashpoint 203°C", British Rose "Flashpoint 192°C" — far above any wax's working range. Where an oil page gives its own instruction, follow it: Gardenia states "Flashpoint 98°C" and "Never pour fragrance oil into wax above its flashpoint temperature." The full treatment is in what flash point means.
It does not "burn off" in the sense of being destroyed. The phrase is loose shorthand for evaporation. The light fraction leaves the vessel as vapour — which is why an overheated melt smells wonderful in the room and the candle does not. Nothing is combusted and no residue is created; material simply relocates from your jar into your kitchen. The distinction matters because evaporation is proportional and selective, so the answer is never "the fragrance is gone", it is "some of the fragrance is gone, and it was the part you noticed first".
And it is not fixed by adding more oil at the same temperature. That reproduces the loss at a higher cost, and if your wax's stated ceiling is 10% — as on CSI 464 — you may also be pushed toward exceeding a formulation limit to compensate for a process error. Fix the process, keep the load where the wax page allows. The load argument is set out in can too much fragrance oil make a candle smell weaker.
Heat does not steal the whole fragrance. It steals the part the customer smells before they pick the jar up.

How to tell afterwards
By the time the jars are set, the temperature is gone and only its consequences are available. Three of those consequences point at heat specifically; the rest are shared with other faults, so this table is about telling heat apart from its neighbours rather than confirming a hunch.
Diagnosis · what points at heat and what points elsewhere
Symptom, the likely cause, and the test that separates them
| What you observe | Points at | The test that settles it |
|---|---|---|
| Recognisable but flat, heavier, "not like the bottle" | Heat. The signature symptom — structure changed, volume mostly there | Smell the bottle beside the cured jar. If the jar is missing the opening rather than the whole scent, heat is the candidate |
| Faint everywhere, cold and hot alike, no character change | Load, cure or wick — not heat | Re-weigh your dose and re-check the cure age before touching temperature |
| Oily film, beading or separation on the surface | Under-mixing, a load over the wax's ceiling, or adding too cold | See separation and added too cold — both look nothing like heat loss |
| Rough surface, sinkholes, wet spots on the glass | Pour temperature and cooling, downstream of an overshoot | Log the pour reading; compare against the wax page's stated pour band |
| Darker or duller colour than the same dye dose last time | Heat and time at heat | Pour two jars from one melt at two dye-in temperatures and photograph both |
Do not diagnose an overheated batch on the evening you poured it. A fresh candle reads weak whatever you did to it, so a same-day verdict on a hot batch is worthless in both directions — you will either condemn a good candle or absolve a bad one. Give it the cure the oil page asks for: most CSI oil pages state 48–72 hours for soy wax, and this series works to 14–21 days for a commercial soy container candle. Then score it blind. The case for waiting is made in why candle makers should test fragrance after curing.
The two-temperature test
This is the only honest way to know what your own overshoot costs you, and it is cheap. One wax, one oil, one wick, one jar size, two add temperatures, four jars each — eight jars in total, which is enough to distinguish a real difference from jar-to-jar noise.

1
Split one melt, do not run two meltsMelt 900 g of Luxury Soy Wax Chunks and divide it into two vessels of roughly 450 g each. One melt means one wax batch, one moisture history and one thermal history up to the split — so the only thing that differs between your two arms is what you do next. Two separate melts introduce a second variable and quietly ruin the test.
2
Arm A: add inside the stated band. Arm B: add above it, deliberately and onceArm A goes in at 85°C, mid-band on the Chunks page's stated 80–90°C. Arm B goes in at whatever overshoot you actually make in real life — if your bad batches run to 98°C, use 98°C. The point is not to find a dramatic number, it is to price the mistake you genuinely make. Write both readings down before you add anything.
3
Hold everything else identical, including the clock9.6 g of oil per jar on a scale, two minutes of stirring in each arm, the same pour temperature inside 75–80°C, the same wick, the same room. Time the interval from adding to pouring and keep it the same in both arms — otherwise you are testing peak temperature and dwell time at once and cannot tell them apart.
4
Label the bases, cover the labels, cure the full periodA1–A4 and B1–B4 on the bottom, plain paper over the labels so the front of every jar is anonymous. Lids on, boxed, out of sunlight, stable room temperature. Score at day 7 and day 14, and if you can get a second person who does not know which arm is which, use them — expectation is the largest error in this whole exercise and it costs nothing to remove.
5
Score for character as well as strengthThis is the step most makers skip, and it is the one that matters here. Use two 1–5 scales per jar: strength, and how close it is to the bottle. Heat loss shows up on the second scale before the first. Then burn one jar per arm and record hot throw at 30 and 120 minutes, minutes to a full melt pool, and any soot or mushrooming.
The CSI principle
You cannot put heat back. You can only find out what it took, once, and then stop paying for it.
Every other variable in candle making gives you a second chance — a wick can be swapped, a load can be adjusted, a cure can be extended. Temperature is the one decision that is finished the moment you make it, which is why it deserves an instrument rather than a habit.
Which oils are most exposed
Exposure follows note structure, not price. A blend whose character lives at the top has more to lose to heat than one whose character lives in the base — and CSI's pages state the note pyramids, so you can read exposure off the listing before you buy. Both tables below show every size, the per-kilogram price, and how many 120 g jars at 8% (9.6 g) a pack covers.

Citrus · the family with the most to lose
Citrus Lemon Fragrance Oil
The page is unusually candid and that makes it the best teaching example in the range. Its Maker's Tip states that citrus fragrances are "notorious for fading in candles faster than warmer fragrance families - the volatile top notes evaporate quickly in heat", and elsewhere that they "have volatile top notes that need full cure time to develop properly". Look at the stated pyramid and you can see why: top "Zesty lemon, lime - sharp, bright, immediately energising", middle "Bright grapefruit, orange", base "Tangy mandarin" — a citrus base under a citrus top, so there is no heavy anchor to survive an overshoot. Stated load "6-10% for soy wax candles, cure 48-72 hours", vanillin "Approximately 0%" and safe for white wax. At ₹2.832 per gram at 1 kg it is also one of the least expensive oils in the range, which makes it the right oil to learn this lesson on rather than the wrong one.
| Size | Price | Per kg | 120 g jars @ 8% |
|---|---|---|---|
| 15 gm | ₹81.42 | ₹5,428 | ≈1 |
| 50 gm | ₹170 | ₹3,400 | ≈5 |
| 100 gm | ₹300 | ₹3,000 | ≈10 |
| 500 gm | ₹1,420 | ₹2,840 | ≈52 |

2
Woody · the family with the least to lose
Sandalwood Fragrance Oil
The structural opposite, and the reason a maker who only pours woods may never notice they overheat. Its stated profile sits almost entirely in the base: main aroma "Warm, creamy sandalwood - smooth, rich, and sophisticated" with an undertone of "Subtle earthy depth - grounding, natural, never sharp", family "Woody / Creamy / Warm". Heavy material is the least volatile material, so an overshoot removes proportionally less of what defines the scent. The page states "Flashpoint 203°C" and says this "gives candle makers very comfortable working margins", vanillin "0%" with no discolouration in white or neutral wax, and a load of "Up to 10% for soy wax, with a cure time of 48-72 hours. Up to 6% for paraffin wax". It is also the anchor of most Indian festive ranges, which is worth knowing when you plan a Diwali run for 8 November 2026.
| Size | Price | Per kg | 120 g jars @ 8% |
|---|---|---|---|
| 15 gm | ₹93.22 | ₹6,214.67 | ≈1 |
| 50 gm | ₹271.40 | ₹5,428 | ≈5 |
| 100 gm | ₹502.68 | ₹5,026.80 | ≈10 |
| 500 gm | ₹2,513.40 | ₹5,026.80 | ≈52 |

₹48.26 per 120 g jar · ₹80.43 per 200 g candle at 1 kg pricing Buy Sandalwood
Priced above: Citrus Lemon ₹2,832 / 1 kg = ₹2.832 per gram · Sandalwood ₹5,026.80 / 1 kg = ₹5.0268 per gram. Per-jar = grams × price per gram: 9.6 × ₹2.832 = ₹27.19 and 9.6 × ₹5.0268 = ₹48.26; the 200 g figures use 16 g. Wax: Luxury Soy Wax Chunks ₹599 / 1 kg = ₹0.599 per gram, so 110.4 g is ₹66.13.
Run the test on 15 g or 100 g, not on a kilo. Citrus Lemon starts at ₹81.42 for 15 g and Sandalwood at ₹93.22, so pricing your own overshoot costs less than one jar of finished candle. Move to 500 g or 1 kg once a logged temperature has produced a candle you would sell. Bulk pricing, GST invoicing, SDS and IFRA documentation are handled on WhatsApp.

Salvage, and what it is worth
Take a real batch: 20 jars of 120 g at 8%, which consumes 2,208 g of wax and 192 g of oil. In Luxury Soy Wax Chunks at ₹0.599 per gram the wax is ₹1,322.59; in Citrus Lemon at ₹2.832 per gram the oil is ₹543.74; twenty Eco Candle Wicks Thin (C1) at ₹5.90 each are ₹118. So the consumables in an overheated 20-jar batch are ₹1,984.34, plus the jars, which are reusable.
Three options, and only one of them is usually right. Re-melting and re-pouring fixes appearance and nothing else — it does not return the lost volatiles, and it exposes the blend to heat a second time, so as a fragrance intervention it makes things marginally worse. Re-dosing — remelting and adding further oil — can restore some presence, but you must weigh what you add, record the new total, and confirm the result stays inside the ceiling your wax page states (13% on Chunks, 10% on CSI 464); and you must judge it after a full cure, not that evening. Demoting the batch — selling it as seconds, using it as tester jars, or keeping it for your own shelves — is the honest answer surprisingly often, because ₹1,984.34 of consumables is less than the cost of a customer receiving a candle that does not smell like its label.
The asymmetry that should decide it. Never re-dose a whole batch on a same-day impression. Re-dose two jars, cure them alongside two untouched jars from the same batch, and compare at day 14. Two jars is ₹198 of consumables and one afternoon; a re-dosed 20-jar batch judged wrongly is ₹1,984.34 plus a second dose plus your time. And at a production scale the arithmetic is brutal — a 500-candle run at 200 g and 8% carries 8 kg of oil, which in Citrus Lemon at ₹2,832 per kilogram is ₹22,656, on top of 92 kg of wax bought as nine 10 kg bags at ₹5,999 plus one 5 kg bag at ₹2,995, or ₹56,986. With 500 wicks at ₹2,950 that is ₹82,592 of materials riding on a thermometer reading. No 25 kg or 100 kg soy pack is listed at CSI, so the listed per-kilogram price is the ceiling; message WhatsApp for a quote on recurring volume.
Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles, and does not manufacture wax or fragrance oil. The commercially convenient version of this page would say that an overheated batch is fixed by buying more oil. It says the opposite: fix the process, hold the load at what your wax page allows, and re-dose only two jars as a test. A maker who can tell a heat problem from a load problem buys the right thing next time, which is the only kind of customer worth having.
Every temperature, load, note structure and flash point quoted here is text published on the linked CSI product page in September 2026, where current wording takes precedence. No figure on this page measures fragrance loss, no laboratory, GC-MS or burn-test result is claimed or implied, and no flash point is estimated or used to derive an add temperature — the wax page's stated band is the reference throughout, and where a wax page states nothing we say so. Load ceilings are wax formulation limits, not regulatory limits.

Frequently asked questions
Does adding fragrance oil too hot ruin the candle?
Rarely ruins it; usually changes it. The lightest materials evaporate, so the candle keeps most of its volume and loses its opening — the Citrus Lemon page describes the mechanism as "the volatile top notes evaporate quickly in heat". A base-heavy woody or gourmand blend may survive an overshoot almost unchanged; a citrus or fresh blend will not. Judge it after a full cure, blind, scoring both strength and how close it is to the bottle.
What temperature is too hot for fragrance oil in soy wax?
Above the band your wax page states. On Luxury Soy Wax Chunks that is above 90°C, since the page states "Recommended fragrance add temp 80-90°C"; on Eco Soy CSI 400 also above 90°C, from its stated "80 to 90 degrees". The CSI 464 and CSI 468 pages state no add temperature at all — ask CSI rather than borrowing one from another wax.
Can I re-add fragrance oil to a batch I overheated?
You can, with three conditions. Weigh what you add and record the new total load; confirm the total stays inside your wax's stated ceiling (13% on Chunks, 10% on CSI 464); and re-dose two jars first, not the batch. Cure those two beside two untouched jars and compare at day 14. Two test jars cost about ₹198 in consumables. Re-melting also exposes the blend to heat a second time, so it is not a free operation.
Will fragrance oil catch fire if the wax is above its flash point?
A flash point is a measured handling and transport classification, not a spontaneous-ignition temperature: it describes the lowest temperature at which vapours form an ignitable mixture with air under a defined test, in the presence of an ignition source. Most CSI oils that publish a measured value state between 185°C and 206°C, far above any wax working range. Follow any instruction the oil page itself gives — Gardenia states "Never pour fragrance oil into wax above its flashpoint temperature." Never use open flame near a melt, and ask CSI for the SDS.
Why do two batches at the same temperature smell different?
Because temperature is an instant and loss is a rate. A blend added at 92°C and poured in ninety seconds has had far less time in the volatile zone than one added at 92°C and left for six minutes. Record the stirring duration and the interval to pouring alongside the reading — the pair describes the event, the reading alone does not. Other candidates are a probe touching the vessel, an unrecorded overshoot before the reading, and room temperature.
Does overheating cause wet spots and rough tops?
Indirectly, and often. A melt that overshot has further to fall before the stated pour band, so either you wait — and the blend sits hot — or you pour above the band. Both make surface faults likelier. Luxury Soy Wax Chunks states a pour of "75-80°C" and, elsewhere, "Pour at 70-80°C"; CSI 468 states "58°C – 60°C". Log the pour reading every time — details in the pouring temperature guide.
Price the overshoot once
Eight jars, two temperatures, one answer you keep for every batch after it.

Figures verified September 2026: Wax specifications quoted verbatim — Luxury Soy Wax Chunks: "Recommended fragrance add temp 80-90°C", "Recommended pour temp 75-80°C", "Pour at 70-80°C into your prepared containers with wicks in place.", "Recommended fragrance load: 8% to 13% of total wax weight"; Eco Soy CSI 400: "add your fragrance or essential oils at 85°C (185°F), stir gently for 2 minutes, and pour directly.", "Fragrance Add Temperature 80 to 90 degrees"; CSI 464: "Pour Temperature 80°C – 90°C", "Melting Point 80°C – 90°C", "Fragrance Load Up to 10%", no add temperature stated; CSI 468: "Melting Point 50°C – 53°C", "Pour Temperature 58°C – 60°C", "Fragrance Load Up to 13%", no add temperature stated. Oil pages, verbatim: Citrus Lemon "Citrus fragrances are notorious for fading in candles faster than warmer fragrance families - the volatile top notes evaporate quickly in heat", "Citrus fragrances have volatile top notes that need full cure time to develop properly", top notes "Zesty lemon, lime - sharp, bright, immediately energising", base "Tangy mandarin", "6-10% for soy wax candles, cure 48-72 hours", "Vanillin content Approximately 0%"; Sandalwood "Flashpoint 203°C", "gives candle makers very comfortable working margins", main aroma "Warm, creamy sandalwood - smooth, rich, and sophisticated", "Vanillin content 0%", "Up to 10% for soy wax, with a cure time of 48-72 hours. Up to 6% for paraffin wax"; British Rose "Flashpoint 192°C"; Gardenia "Flashpoint 98°C", "Never pour fragrance oil into wax above its flashpoint temperature." Of 107 CSI fragrance oil pages, 18 state a specific measured flash point; the template line "Flash point > 93°C (suitable for alcohol-based products)" on 32 pages is a threshold for alcohol-based products, not a measurement, and is not reported as one here. Load is a share of the finished candle: 200 g at 8% = 184 g wax + 16 g oil; 120 g jar = 110.4 g + 9.6 g. Prices used: Chunks ₹299 / 500 g, ₹599 / 1 kg, ₹2,995 / 5 kg, ₹5,999 / 10 kg (₹0.599/g); Citrus Lemon ₹81.42 / 15 gm, ₹300 / 100 gm, ₹2,832 / 1 kg (₹2.832/g); Sandalwood ₹93.22 / 15 gm, ₹5,026.80 / 1 kg (₹5.0268/g); Amber Shiny Glass Jar ₹236 / pack of 5; Eco Candle Wicks Thin (C1) ₹59 / 10, ₹118 / 20, ₹2,950 / 500 at ₹5.90 each; Pen Thermometer ₹354; Mini Electric Wax Melter ₹2,360. Eight-jar test: ₹599 + ₹300 + ₹472 + ₹59 = ₹1,430, or ₹178.75 a jar. Twenty-jar batch: 20 × 110.4 g = 2,208 g wax at ₹0.599 = ₹1,322.59; 20 × 9.6 g = 192 g oil at ₹2.832 = ₹543.74; 20 wicks at ₹5.90 = ₹118; total ₹1,984.34. Two re-dosed test jars ≈ ₹198 of consumables. 500-candle run: 8 kg oil at ₹2,832 = ₹22,656; 92 kg wax bought as (9 × ₹5,999) + ₹2,995 = ₹56,986 for 95 kg; 500 wicks ₹2,950; total ₹82,592. No 25 kg or 100 kg soy pack is listed, so listed per-kilogram prices are the ceiling and recurring volumes are quoted on WhatsApp. Cure periods of 14–21 days for soy container candles reflect standard practice; 48–72 hours is what most CSI oil pages state.
