Yes. It is the single biggest lever you control, because the hotter the wax is when it enters the jar, the further it has to contract on the way down. But hotter is not simply worse — there is a band, and this page is about finding your number inside it.
80–90°C
the melt-and-pour band CSI publishes for Eco Soy CSI 400 and Luxury Soy Wax CSI 464 · pen thermometer ₹354 · CSI live pricing, September 2026
Quick answers — read this first
Does pour temperature cause sinkholes? Yes, and it is the biggest lever on the bench. Wax shrinks as it goes from liquid to solid. The hotter it is when you pour, the more temperature it has to lose, and the more total shrinkage happens inside a jar that has already skinned over on top. That trapped shrinkage is the cavity.
So should I pour as cool as possible? No. Pour too cool and you trade the sinkhole for a rough, lumpy top, poor adhesion to the glass and a visible pour line. There is a band, not a minimum.
What band? CSI publishes 80–90°C for melt and pour on Eco Soy CSI 400 and Luxury Soy Wax CSI 464. For waxes where no band is published, ask us on WhatsApp rather than copying a figure from a foreign blog.
How do I find my number? Pour three jars at three temperatures across the band, cool them identically, cut them open at 48 hours and look. The ₹354 pen thermometer is what makes that test mean anything.
The short answer
Yes — it is the biggest single lever. Total contraction scales with how much temperature the wax has to shed after it is in the jar. Pour hotter, shed more, contract more, sink more.
But there is a floor as well as a ceiling. Below the band you get rough tops, poor glass adhesion and a visible pour line. The published band for Eco Soy CSI 400 and CSI 464 is 80–90°C.
Add temperature is a different number from pour temperature. One is set by fragrance solubility, the other by contraction and finish. CSI 400 specifies fragrance in at 80–90°C with two minutes of stirring.
The two defects move in opposite directions, which is why "pour cooler" is only half an instruction. Sinkhole depth rises with pour temperature because hotter wax has more contraction still to do inside the jar; rough tops, poor glass adhesion and a visible pour line rise as you drop below the band. The black segment is the 80–90°C melt-and-pour band CSI publishes for Eco Soy CSI 400 and Luxury Soy Wax CSI 464. Bar heights show direction and relative severity, not measured millimetres.
Yes — and of everything you can change on the bench, it is the single biggest lever. Wax occupies more volume hot than cold, so every candle shrinks as it sets. The amount of shrinking is set by how much temperature the wax still has to lose after it is in the jar. Pour at the top of the band and the wax has further to fall, so more of the total contraction happens after the top surface has already skinned over and locked in place — and shrinkage that cannot pull the surface down pulls a cavity open underneath it instead. That is the sinkhole. The mechanism is set out in full in the sinkhole guide, and the prevention checklist is its own page. What this page owns is the temperature variable. Hotter is not simply worse. Pour below the band and you swap one defect for three: a rough, grainy top, poor adhesion to the glass, and a visible pour line where the second pour met the first. CSI publishes 80–90°C for melt and pour on Eco Soy CSI 400 and Luxury Soy Wax CSI 464. Your number lives inside that band, and you find it by pouring three jars at three temperatures and cutting them open. Everything else on this page is how to run that test and how to hold the answer across fifty jars.
One line: pour temperature is the biggest lever on sinkholes, the published band for CSI 400 and CSI 464 is 80–90°C, and the only way to find your number inside it is three jars, three temperatures and a ₹354 thermometer.
You cannot run any of this from memory. Pen Thermometer for Candle Making, ₹354 — the cheapest item on this page and the one that makes every other instruction on it enforceable.
A sinkhole is not wax that went missing. It is wax that got smaller, in a container that would not let it get smaller from the top.
Take the physics in plain terms, because the arithmetic is not the point and the direction is. Molten wax is loose and disordered, and it takes up more room than the same mass of set wax, where the molecules have packed into a crystal structure. Cooling closes that gap. The distance the wax has to travel from its pour temperature down to room temperature is the distance over which all of that packing happens — and the further it travels, the more total volume it gives up.
Now add the jar. The surface of a container candle is exposed to air and cools first, so it sets first. Within a few minutes there is a skin across the top while the middle is still liquid. Everything that contracts after that moment is contracting under a lid it made itself. The liquid core pulls inward and downward, the set top will not follow it, and the space that opens up between them is the void you find when you cut the candle open — usually a well around the wick, sometimes a cavern under an apparently perfect surface. The pour temperature decides how much contraction is left to happen after the skin forms. That is the whole relationship.
This is also why the defect is so unevenly distributed across a batch. Two jars poured from the same jug ninety seconds apart are two different pour temperatures, and if you are near the top of the band, that gap is enough to give you one clean candle and one with a well. Makers read that as randomness and start blaming the wax, the fragrance or the jar. It is not random. It is an uncontrolled variable, and the reason it feels random is that nobody wrote the number down. The full mechanism — crystal structure, cooling gradient, why soy does this more visibly than paraffin — belongs to the sinkhole mechanism guide, and the checklist of fixes belongs to the prevention page. If you have three defects at once and are not sure which one you are looking at, start at the defect hub.
What this does and does not promise. Dropping your pour temperature reduces the depth of the cavity. It does not, on its own, guarantee a flat top on every jar in every ambient condition, because cooling rate, jar wall thickness, fill depth and room temperature all still matter. What it does do is remove the largest and cheapest source of variation before you go chasing the smaller ones. Fix the biggest lever first, then re-test. Do not change pour temperature, jar and wax in the same batch — you will improve the candle and learn nothing you can repeat.
The band, and where CSI publishes one
If pouring cooler reduced sinkholes and had no other effect, the instruction would simply be "pour as cool as the wax will let you". It is not, because the cool end of the range has its own failures, and they are the ones customers see on the shelf.
Pour too cool and the wax is already part-crystallised as it leaves the jug. It arrives thick, it does not level, and it sets with a rough, grainy, sometimes lumpy top. It also fails to wet the glass properly, which is where wet spots and poor adhesion come from — those pale patches where the wax has pulled away from the wall and the jar looks second-hand before it has been lit. And if you top up a sunken candle with wax that is too cool, the repair does not fuse: you get a visible pour line, a horizontal tidemark across the candle that is arguably uglier than the sinkhole you were fixing.
Two failure directions · one variable

What improves
What gets worse
What the customer sees
Above the band
Glass adhesion, surface smoothness, self-levelling, fusing on a top-up
Total contraction after skinning; deeper and wider cavities; more wick-well
A candle that looks perfect and has a hole in it, or a top that collapses on first burn
Inside the band
Both, within tolerance — this is the working compromise the wax was formulated for
Nothing, provided cooling is controlled and consistent
A flat top, wax against glass all the way round, no tidemark
Below the band
Cavity depth — least contraction left to happen
Levelling, glass adhesion, fusing between pours, surface texture
A rough or lumpy top, wet spots on the glass, a visible pour line
So the useful question is not "how cool can I go" but "where inside the published band does this wax, in this jar, in this room, give me the flattest top". CSI publishes 80–90°C as the melt and pour band for Eco Soy CSI 400 and Luxury Soy Wax CSI 464. Those are the two waxes we have a published band for, and they are the two this page can give you numbers on. Eco Soy CSI 400 is ₹399 for 1 kg and ₹1,996 for 5 kg; CSI 464 flakes are ₹260 for 500 g, ₹507.40 for 1 kg, ₹2,537 for 5 kg and ₹5,074 for 10 kg. Both are in stock as of the September 2026 pull.
Where CSI publishes no band — say so, do not guess
For the rest of the range — Luxury Soy Wax Chunks, Premium Coconut Soy CSI 468, pillar wax, beeswax, paraffin and the gel and speciality waxes — CSI does not publish a pour temperature band, and this page will not invent one for you. A number copied off an overseas forum for a differently formulated wax is not data; it is a guess wearing a decimal point. Message us on WhatsApp at +91 7397976926 with the exact product and we will tell you what the manufacturer states for that wax, or tell you plainly that nothing is published and that you should run the three-pour test in the next section to establish your own working figure. Ask on WhatsApp.
One more thing the band does that is easy to miss: it is a melt and pour band, not a pour-only band. Overheating wax well past the top of its band before you ever get to the jar is its own problem — it degrades the wax, it accelerates fragrance loss, and it means you then have to wait while it comes back down, which is exactly the interval where most makers stop watching the thermometer. Heat to the band, work in the band, pour in the band.
Add temperature and pour temperature are two different numbers
This is the confusion that costs makers the most, and it is a naming problem as much as a technical one. Most people run their whole process off one figure — "I pour at 65" or "I do everything at 80" — because they have only ever seen one number quoted. There are two, they are doing two unrelated jobs, and they happen at two different moments.
1
Add temperature — the fragrance numberThis is the wax temperature at the moment you pour the fragrance oil in, and it exists for one reason: solubility. Too cool and the oil is suspended in the wax rather than dissolved into it, which is how you get separation, sweating and a weak throw. Too hot and the lighter aromatic molecules flash off before the wax ever reaches the jar. Eco Soy CSI 400 specifies fragrance added at 80–90°C, with two full minutes of stirring. Two minutes is a long time with a bamboo stirring stick (₹118 for 5) in your hand — time it rather than estimating it, or use the CSI Pro Mixer at ₹349 for an even incorporation without the arm ache. Nothing about this number has anything to do with sinkholes.
2
Pour temperature — the physics numberThis is the wax temperature at the moment it enters the jar, and it exists for a completely different reason: contraction and finish. It decides how much shrinkage is still to come after the surface sets, and therefore how deep the cavity is; it also decides how well the wax wets the glass and how smooth the top is. It has nothing to do with fragrance solubility. For CSI 400 and CSI 464 the published melt-and-pour band is 80–90°C.
3
Why they get conflatedBecause on CSI 400 the two bands overlap. The wax is specified for melt and pour at 80–90°C and for fragrance addition at 80–90°C, so a maker following the instructions correctly can go from stir to pour without the number changing — and reasonably concludes there is only one number. Change wax, or add a two-minute stir and a walk across the workshop, and the two come apart immediately. Write them as two rows on your sheet even when they read the same. The moment you switch wax, you will need to know which of the two you were recording.
4
There is a third, and it is the one nobody recordsAmbient temperature — the room the jars cool in. A Chennai afternoon and a Shimla morning are not the same cooling curve, and the same pour temperature will give you different results in each. It is not a number you set, but it is a number you note, because it is the reason a recipe that worked in February stops working in May. Arzoo Vyas's review above is exactly this problem described from the inside: "So I live in a very cold region and it was becoming very difficult for me to maintain the temperature."
The distinction, stated once
Add temperature is about whether the fragrance dissolves. Pour temperature is about how far the wax still has to shrink. They are not the same question, and a single remembered number cannot answer both.
On Eco Soy CSI 400 both happen to fall in the same 80–90°C band, which is convenient and also exactly why the two get merged in people's heads. Record them separately anyway.
Two waxes on the store carry a published melt-and-pour band. Eco Soy CSI 400 at ₹399/kg and Luxury Soy Wax CSI 464 from ₹260/500g — both specified at 80–90°C. If you are running a defect test, run it on one of these first, then carry the method across.
The three-pour test: how to turn an opinion into a setting
Everything above tells you which direction to move. Only a test tells you where to stop. This is the smallest experiment that produces a number you can put on a spec sheet, and it costs one afternoon and roughly 600 g of wax.

Published band · cheapest soy per kg
Eco Soy CSI 400
The wax to run this test on if you have not run it before, because it is the one with the most published detail behind it: melt and pour at 80–90°C, fragrance in at 80–90°C, stir two full minutes. It is also the cheapest soy per kilogram in the range, which matters when you are deliberately going to cut three finished candles in half. Arminder Kaur's review of it is short and unhelpful about temperature, which is honest — "Good quality wax" — so treat it as a product review and not as evidence for this method.

Luxury Soy Wax CSI 464 (Flakes)
The other wax with a published 80–90°C melt and pour band, and the one most CSI container makers are actually running. Flake form melts faster and more evenly than chunks, which reduces the temperature spread inside the melt before you have poured a single jar — a real advantage when the whole exercise is about controlling temperature. Thenirvaofficial's review calls it "One of the best wax for container Candles. Easy to work with, especially if you are a beginner." — again, a general product review, not a verdict on pour temperature.

Hold everything constant except the one variableSame wax, same batch, same bag. Same fragrance at the same load, added at the same temperature with the same stir time. Same jar — three identical vessels, so a White Matte Glass Jar pack of 5 at ₹354 (₹70.80 each) gives you three plus two spares. Same wick, same fill weight to the gram on a weighing scale at ₹354. Same room.
2
Pour at three points across the bandFor a wax published at 80–90°C, pour jar A at the top of the band, jar B in the middle, jar C at the bottom. Read the temperature in the jug, at the moment of pouring — not when you took it off the heat. Label each jar on the base before you pour, not after, because three unlabelled white candles look identical ninety seconds later.
3
Cool all three identicallySame shelf, same spacing, no draught, no fan, nothing underneath them that conducts heat differently. Do not put one on a metal counter and two on wood. If you cover them, cover all three the same way. Note the room temperature at pour and again at two hours. Cooling rate is a second variable and you are not testing it today — you are holding it still.
4
Wait 48 hours, then cut them openNot four hours. Contraction continues well past the point where the surface looks finished, and a candle that looks flat on Tuesday evening can show a well by Thursday. At 48 hours, photograph each top, then cut each candle vertically through the wick with a warm knife and photograph the cross-section. The cross-section is the actual result. A flat top with a cavern under it is a failure that will announce itself on the customer's first burn.
5
Read the two failure modes against each otherYou are not looking for "no cavity". You are looking for the coolest pour that still gave you a smooth top and full contact with the glass. If jar C is cavity-free but rough and patchy, your number is between B and C. If all three are clean, your number is C and your problem was never temperature — go back to the defect hub.
6
Write the winning number on the wax, and re-run it when anything changesNew wax batch, new jar, new season: re-run. It is three jars. The test that took you an afternoon the first time takes an hour the second, and it is the difference between a spec and a superstition.

Why guessing fails, and what changes at fifty jars
Here is the part that makes every instruction above unenforceable without one ₹354 purchase. Wax in a metal jug cools fast. Steel is there precisely because it conducts heat well, which is excellent for melting and inconvenient for holding. The temperature you melted at is not the temperature you poured at, and the gap between them is not small — it is the whole width of the band, crossed in the time it takes to wipe a jar rim, straighten a wick and answer the door.
So a maker who says "I pour at 80" is usually reporting the last number they saw, which was on the melter, several minutes before the wax reached the glass. They are not lying. They are describing a different moment. The reading that matters is taken in the jug, at the instant of pouring, every time — and the Pen Thermometer for Candle Making at ₹354 is the fix. Not an approximation of the fix. It is the cheapest item in this entire guide, it costs less than a single 500 g bag of CSI 464 at ₹260 plus a pack of jars, and without it every other sentence on this page is decoration.
The failure this produces at volume. You pour fifty jars from one melt. The first jar goes in at the top of the band. By jar fifty — twenty minutes and a lot of surface area later — the wax in the jug is well below the bottom of it. You have not run one batch. You have run a continuous, uncontrolled temperature sweep from one end of the band to the other, and then past it. That is why a fifty-jar run so often comes out as roughly fifteen good candles, twenty acceptable ones and fifteen with rough tops or tidemarks, and why nobody can work out what went wrong: nothing went wrong at any single moment, the variable simply drifted.
1
Work in sub-batchesDecide how many jars you can fill inside your band and make that your sub-batch size. Ten to fifteen is realistic for most people with a jug. Fill the jug, check the temperature, pour that many, return to the melter, re-check, refill, repeat. It feels slower. It is faster than remaking rejects, and it is the zero-rupee version of the fix.
2
Keep the melter on and draw from itA heated reservoir holds the band for you instead of you chasing it. The Mini Electric Wax Melter (1 L, one year warranty) at ₹2,360 is the entry point and Tanya Walia's review is about exactly this shift: "I used to double boil and was thinking of quitting due to the complexity of it and the time it took. Now i just leave my wax in the melter and thats it." For production volume the 20-litre Electric Wax Melter at ₹23,600 or the imported 10 kg unit at ₹21,240 take the drift out of a fifty-jar run entirely. Priya Singh, four stars, wants the mini one in a bigger size — "Plz launch same product in 2-3 litre also" — which tells you where the 1 L unit runs out.
3
Cut the transfer distanceEvery metre between melter and jar is temperature lost. Pour where you melt. A Candle Wax Pouring Jug at ₹531 or the 600 ml Steel Pouring Pitcher at ₹708 with a controlled spout means fewer stops to correct drips, which means fewer seconds between the first jar and the last.
4
Fix the survivors with heat, not with a second pourWhere a jar has already set with a dipped top, a Hot Air Gun at ₹531 re-melts the top layer so it flows level and re-fuses, with no tidemark. A cool top-up pour leaves the line. This is a repair, not a process — if you are doing it on more than a jar or two per batch, your pour temperature is the problem, not your finishing.
No additive fixes a number you never measured. A thermometer costs ₹354 and tells you the truth every time.
— CandleMakingSuppliesIndia
We sell additives, so read this as an argument against our own interest. Vybar Additive is ₹156 for 50 g and ₹312 for 100 g, and it is a legitimate product with legitimate uses. It is not a substitute for a thermometer, and if you buy it to make sinkholes go away without changing anything else, you have bought a consumable to paper over a measurement you are still not taking. The additive gets used up. The thermometer does not. Buy the ₹354 tool, run the three-pour test, get your number, and then decide — with data in front of you — whether you also want an additive. Doing it in that order is cheaper for you and, over a year of reorders, worse for us. That is fine.
The commercial case is straightforward. A rejected jar is not a small loss: it is the wax, the fragrance, the wick, the jar, the electricity and the twenty minutes, and at production volume it is also a delivery date. Costing that out properly is covered in how to price candles in India in 2026 and whether candle making is actually profitable. If your reject rate on tops and cavities is running at even one jar in ten, a ₹354 thermometer pays for itself inside a single batch of fifty, and the process discipline it forces is the same discipline you will need at a thousand orders a month.
Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. The commercially convenient version of this page would sell you an additive for every defect. Instead the recommendation is a ₹354 thermometer and a free test, because a maker whose reject rate falls keeps reordering wax, and a maker who buys additives to hide an unmeasured variable eventually stops making candles.
The 80–90°C figure quoted throughout is the melt-and-pour band CSI publishes for Eco Soy CSI 400 and Luxury Soy Wax CSI 464, and the two-minute stir at 80–90°C is the fragrance-addition specification for Eco Soy CSI 400. Where CSI does not publish a band for a wax, this page says so and routes you to WhatsApp rather than supplying a number. No coefficients of expansion, no shrinkage percentages and no "ideal pour temperature" figures have been invented here; the relationship between pour temperature and contraction is described directionally because that is what can be stated honestly.
Every price is taken from live CSI stock on 10 September 2026 and links to the product page, where current pricing and specification always take precedence.

Frequently asked questions
Does pouring temperature cause candle sinkholes?
Yes, and it is the biggest single lever you control. Wax takes up more volume hot than cold, so the further the wax has to cool after it is in the jar, the more it contracts — and once the top surface has set, that contraction pulls a cavity open underneath instead of pulling the surface down. Pour hotter, contract more, sink deeper. It is not the only cause, but it is the one to fix first because it is free to change and easy to measure.
What temperature should I pour soy wax at?
It depends on the wax, and you should use the band the manufacturer publishes for the one you bought. CSI publishes 80–90°C for melt and pour on Eco Soy CSI 400 and Luxury Soy Wax CSI 464. For other waxes in the range CSI publishes no pour band, so ask on WhatsApp and, in the meantime, establish your own working figure with the three-pour test above rather than borrowing a number written for a different formulation.
If cooler pouring reduces sinkholes, why not pour as cool as possible?
Because you swap one defect for three. Below the band the wax is already part-crystallised when it leaves the jug: it does not level, so you get a rough or lumpy top; it does not wet the glass properly, so you get wet spots and poor adhesion; and a cool top-up will not fuse with the wax underneath it, so you get a visible pour line. The target is the coolest pour that still gives a smooth top and full glass contact — a point inside the band, not below it.
What is the difference between add temperature and pour temperature?
They are two different numbers doing two different jobs. Add temperature is the wax temperature when the fragrance oil goes in, and it exists for solubility — too cool and the oil sits suspended rather than dissolved, too hot and the light molecules flash off. Pour temperature is the wax temperature when it enters the jar, and it exists for contraction and finish. On Eco Soy CSI 400 both fall in the same 80–90°C band, with two minutes of stirring specified at the add step, which is exactly why makers merge them. Record them as separate rows anyway.
Why do my first and last jars in a batch come out differently?
Because they were poured at different temperatures. Wax in a steel jug loses heat quickly, so a fifty-jar run poured from one melt is a slow temperature sweep, not a single setting. Work in sub-batches of ten to fifteen, returning to the melter and re-checking between them, or keep a heated reservoir on and draw from it — the Mini Electric Wax Melter is ₹2,360 and the 20-litre unit is ₹23,600.
Will an additive stop sinkholes so I do not need a thermometer?
No. Vybar Additive at ₹156 for 50 g is a real product with real uses, but no additive substitutes for measuring the variable that is causing the problem. An additive is a recurring cost that masks an uncontrolled setting; a pen thermometer at ₹354 is a one-off cost that removes it. Measure first, run the three-pour test, then decide whether you still want the additive.
Measure it, then set it

About this guide: Written by the CANDLEMAKINGSUPPLIESINDIA team. Product recommendations reflect the CSI range; the three-pour test method, the record sheet and the sub-batch logic apply to any supplier's wax.
Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on the product pages named. Names, star ratings, dates and products are as recorded by Judge.me, and only reviews Judge.me recorded as verified purchases carry a "Verified buyer" label — Arzoo Vyas's review is published without that label. All six are general reviews of the products they are attached to, not reviews of the pour-temperature method described here. Two longer reviews are shortened with an ellipsis and are otherwise unedited.
Figures verified 10 September 2026: The 80–90°C band is the melt-and-pour temperature CSI publishes for Eco Soy CSI 400 and Luxury Soy Wax CSI 464; Eco Soy CSI 400 additionally specifies fragrance addition at 80–90°C with two minutes of stirring. CSI publishes no pour-temperature band for its other waxes, and none has been estimated on this page. No expansion coefficients or shrinkage percentages are stated anywhere here, because CSI publishes none.
