"So I live in a very cold region and it was becoming very difficult for me to maintain the temperature. My temperature would drop within seconds due to which I was not getting a good hot throw. Moreover, it would take me ages to melt the wax. But this mini melter is my saviour. It took me seconds to melt my wax and the wax stays warm for a longer time in the melter so I was finally able to get the desired hot throw. It is totally worth the money and so hassle-free."

CSI Diagnostics · The Slow 20 kg Pot
A big pot keeping its heat is physics. What it does to your pour session is not inevitable: log the pot, the wall and every pitcher, then pour to a planned window with a restir before every draw.
45 draws
pitcher fills for a 20 kg batch at three 150 g candles each (worked example) · CSI live pricing, September 2026
Quick answers — read this first
Why does my 20 kg pot cool so much more slowly than my 1 kg test? A big pot holds far more heat for its surface area, and heat escapes through the surface. In the worked example the 1 kg pot falls about 0.8°C a minute and the 20 kg centre about 0.05°C a minute. That part is physics, not a fault.Can that change fragrance mixing and consistency? Yes, as a tendency. Scented wax sits hot for much longer, the wall and surface cool while the centre stays hot, an unstirred pot can drift between the first draw and the last, and each pitcher cools fast once it leaves the pot. The first and last candles can leave in different conditions.
How do I find out whether it is affecting my candles? Keep a pot cooling log through a real session: centre and wall every ten minutes, the pitcher at its first and last jar, and every jar marked with its draw number. Retain two candles each from the first, a middle and the last draw, and compare them at the same cure age.
What should the plan be? A pour window: hold the pot inside the wax page's range (CSI 464: 80–90°C, never reheated above 90°C) and pour into the 150 g jar at 80–85°C, the jar's rating. Restir the full depth before every draw, and size each pitcher fill so its last jar is still in the window. Reheat only within the range, and write every reheat down.
The short answer
The cause: slower cooling of a big mass (physics) turning into longer hold at heat, a wall-to-centre gap and first-versus-last differences (tendencies) unless the session is managed.
The test: a pot cooling log over a real pour session (centre, wall, pitcher first and last jar, draw number) plus retained candles from draws 1, middle and last.
The plan: split the batch into pitcher draws sized to the window, restir the full depth before every draw, reheat only within the page's range, log every reheat.
The cost: nothing extra in materials: the log runs on a production batch (₹29,432.53 of materials for 133 candles in the worked example, excluding labour, freight, packaging and GST); six retained candles are ₹1,327.78 of that.

A worked-example cooling log drawn to scale. The 1 kg test pot leaves the pour window within about ten minutes, so every test candle was poured fresh. The 20 kg pot barely moves at the centre over two hours while its wall runs cooler, and each pitcher drawn from it falls fast: by the third draw shown, the last jar is below the window. The readings are illustrative, not CSI data.

Straight answer
My 20 kg wax batch cools much more slowly than my 1 kg test batch. Can production scale affect fragrance mixing and finished candle consistency?
Yes, it can, though the slow cooling itself is normal: a big pot holds much more heat for its surface area, so it loses temperature slowly. The risk is in what that does to the session. In a 1 kg test, every candle is poured within minutes of the oil going in. In a 20 kg session, scented wax sits hot for an hour or more; the wall and surface cool while the centre stays hot; if the pot isn't restirred, the first and last draws may not be the same wax; and each pitcher cools quickly once it leaves the pot, so late jars can be poured below the window. Longer holding at heat tends to wear the lighter top notes, and uneven mixing or cool pours tend to show as first-versus-last differences. Find out whether it is happening with a pot cooling log through a real session, with jars marked by draw number and candles retained from the first, a middle and the last draw. Then plan the session as a pour window: pot held inside the wax page's range, a full-depth restir before every draw, pitcher fills sized so the last jar is still in the window, and reheats only within the range, each one logged.
One line: the slow pot is physics; the inconsistency comes from the session, so log the pot and pitchers and pour to a planned window with a restir before every draw.
The pitcher sets the temperature at the jar. The Large 600 ml Steel Pouring Pitcher is ₹708.00 and in stock on 26 September 2026 (the Small is out of stock). Weigh one full fill, log its first and last jar, and you know how big each draw can be.

Why the big pot keeps its heat
Twenty times the wax is not twenty times the surface. That is the whole story of the slow pot.
A pot loses heat through its surface and walls; it stores heat in its whole mass. Scale up the batch and the mass grows much faster than the surface it cools through, so each kilogram has less surface to lose heat from, and the pot cools more slowly. A 1 kg test in a small pot drops out of the pour window in minutes. A 20 kg pot can sit in it, or above it, for an hour or more. In the worked example on the chart, the test pot falls about 0.8°C a minute and the 20 kg centre about 0.05°C a minute, roughly 16 times slower. Your pots, lids and room will give different numbers, which is why you log them.
The pot also stops being one temperature. Wax against the steel wall and at the surface cools first; the centre stays hot. In the example the wall runs about 0.075°C a minute, a few degrees below the centre within the hour. A ladle or pitcher dipped near the wall gets cooler wax than one dipped in the middle, and unless you stir, the pot slowly separates into zones.
None of that is a problem with the wax or the oil, and it is why this page does not ask you to buy different materials. It asks you to manage the time the batch spends between oil-in and the last jar.
What slow cooling does to a pour session
The table ranks the effects we would suspect when a 20 kg batch is less consistent than the 1 kg test, most likely first. The ranking is editorial judgement, not measured data; each effect is a tendency, and CSI publishes no measured throw or composition data.
Differential table · 20 kg batch less consistent than the 1 kg test
Ranked most likely first (judgement) · each rule-in and rule-out comes from the cooling log or the retained candles
| # | What the candles show | Likely session cause | Rules it in | Rules it out |
|---|---|---|---|---|
| 1 | Last-draw candles poured cooler: rougher tops, poorer glass contact | Pitchers falling below the window before their last jar | Last-jar readings under 80°C in late draws | Every last jar at or above 80°C |
| 2 | First and last candles smell different, at the same cure age | Pot not restirred between draws; wall-to-centre gap | No restir logged; wall several degrees below centre | Restir before every draw, gap small, still different |
| 3 | The whole batch a little flatter at the top of the scent than the test | Long hold at heat before and during the session | Oil-in to last jar measured in hours, not minutes | Session as short as the test's |
| 4 | Early candles poured too hot: sinkage, jar near its limit | Pouring straight from a pot still above the window | First pitcher readings above 85°C in the 150 g jar | First draws inside 80–85°C |
| 5 | Oil on the surface of the last candles | Separation in a cooling, unstirred pot | Oiliness tracks draw number (3227 diagnoses it) | Oiliness scattered through the run |
| 6 | Differences unrelated to draw number | Not the session: basis, lots, cure age | Candles differ batch-wide, not by draw | Differences follow draw order (3274 rebuilds the sheet) |
Rows 1 to 4 are what the cooling log is built to show, and all four have a process fix. Row 5 has its own diagnostic post; row 6 means the session is probably fine and the difference lies elsewhere, which the test-versus-production sheet finds.
Mistake: waiting for the whole 20 kg pot to "come down" to pour temperature with the oil already in. What it does: it can add an hour at heat to every candle in the batch, which the 1 kg test never had. Fix: follow the wax page for when the oil goes in (for CSI 464, keep the pot inside its stated 80–90°C) and plan the pitchers so you pour as soon as the pot is in range, rather than holding scented wax hot while you wait.
The pot cooling log
One production session, logged properly, tells you more than a month of guessing.
Run it on a normal production batch. The worked example is 20 kg of CSI 464 at 8% of total weight with Fallen Leaves: 1,600 g of oil and 18,400 g of wax, 133 candles of 150 g (12 g of oil and 138 g of wax each), with 50 g left over in the pot and pitcher. At 3 candles per fill that is 45 pitcher draws.
1
Set up the sheet before you heatColumns: clock time, minutes since oil-in, pot centre, pot wall (about 2 cm in), draw number, pitcher at the first jar, pitcher at the last jar, restir (yes or no), reheat (from and to). Mark jar bases in draw order as you go: D1-1, D1-2, D1-3, D2-1 and so on.
2
Record oil-in and the stirWrite the pot reading when the oil goes in, how long you stirred and with what. The wax page's figures govern: for CSI 464 that is its stated 80–90°C range. The stir routine for big pots is covered in the first-candle-equals-last-candle mixing post; here you just record what you did.
3
Read the pot every ten minutes, centre and wallSame depth each time. If the pot sits in a melter that holds temperature, log the display too, beside your own reading; how far those two differ is a question for the melting-equipment post.
4
Read every pitcher twiceAt the first jar and at the last jar of each draw. This is the reading that tells you whether a jar was poured in the window; the pot reading alone cannot.
5
Retain six candlesTwo from draw 1, two from a middle draw, two from the last draw. Label them with draw numbers and pour times. Their material value is ₹1,327.78 in the worked example; they are your evidence, not a loss.
6
Compare at the same cure ageLook (tops, glass contact, any oil on the surface) at 24 hours; burn one of each group on separate evenings at your usual test age, same room and trim, and score throw blind 0–3 on entering.
Two thermometers make a 20 kg session easier
With one reader in the pot and one in the pitcher, you never have to choose between logging and pouring. Check them against each other in the same wax before you start; if they disagree by more than a degree or two, note the offset and apply it.The pour-window plan
Once you have one log, turn it into a plan for every 20 kg session. Four rules do most of the work.
1 · Split the batch into draws you can finish in the window. For CSI 464 in the 150 g Clear Glass Jar with Golden Lid, the window at the jar is 80–85°C: inside the wax page's 80–90°C and the jar page's "Safe for hot pour up to 85°C". Size each pitcher fill so its last jar is still at or above 80°C. If your log shows the last jar of a 3-candle fill dropping below 80°C in late draws, fill for two, pour faster, or warm the pitcher by rinsing it with hot wax from the pot before the draw. The other end matters too: early in the session, when the pot is near the top of its range, a fresh fill can read above 85°C, so let it fall to 85°C in the pitcher before the first jar.
2 · Restir the full depth before every draw. The same short routine each time, reaching the base and scraping the wall, with the stirrer head kept under the surface. Time it and write the time on the SOP (a worked example is 30 seconds with a paddle; yours depends on the pot and tool). Drawing from the centre of an unstirred pot gives you the hottest wax, not the average.
3 · Reheat only inside the page's range, and log it. If the pot centre drifts toward 80°C with draws still to go, reheat gently to a figure inside 80–90°C and restir before the next draw. Never above 90°C, the top of the CSI 464 page's range. Each reheat adds time at heat, so if the log shows several per session, the batch is too big for your pour rate.
4 · Keep oil-in to last jar short. Get jars, wicks and trays ready before the oil goes in. In our judgement the single biggest difference between a test and a production session is the hold while the bench gets organised. If the whole batch cannot be poured in a reasonable window at your pour rate, two 10 kg batches are the honest fix: they cost the same in wax and oil.
Pour-window plan · worked example
20 kg of CSI 464 at 8% · 150 g jars · one Large 600 ml pitcher · figures to replace with your own log
| Item | Plan | Where the number comes from |
|---|---|---|
| Pot range | 80–90°C, never reheated above 90°C | CSI 464 page: pour 80–90°C |
| Jar window | 80–85°C at the jar | 150 g jar page: hot pour up to 85°C; the lower limit governs |
| Candles per draw | 3 (450 g), cut to 2 if the last jar reads under 80°C | Your weighed pitcher and your log |
| Draws per batch | 45 for 133 candles | Candles ÷ candles per draw, rounded up |
| Restir | Before every draw, full depth, same routine | Judgement; timed and written down |
| Reheat | Only inside 80–90°C, every one logged | CSI 464 page range |
| Retained candles | Two each from draws 1, middle, last | This log |
Mistake: fixing cool late jars by heating the pot hotter at the start. What it does: the first draws go into the jars too hot for a jar rated to 85°C, and the batch spends even longer at heat. Fix: the pot stays in its range; the draw size and the restir are what change. Pour temperature bracketing by season is a separate question (3272).
Reading the log and the retained candles
If the readings stayed in the window and the retained candles match, scale isn't your problem. If not, the log shows exactly where it went wrong.
Decision rule · cooling log + retained candles
"Differ" = both candles of a draw group score at least 1 point from both draw-1 candles, or show a fault they don't (our judgement) · cure age matched
| What you find | What it points to | Plan change | Purchase |
|---|---|---|---|
| Every last-jar reading at or above 80°C; draw groups alike | The session is under control; scale isn't hurting | Keep the plan; look elsewhere if the batch still differs from the test (3274) | Nothing |
| Late last-jar readings under 80°C; late candles rougher or poorer glass contact | Pitcher cooling in late draws | Smaller fills late in the session, faster rhythm, warm the pitcher | A second Large pitcher only if the pot waits on the pitcher |
| Wall well below centre, no restir logged, first and last smell different | A drifting, unstirred pot | Full-depth restir before every draw (the 10 kg uniform-batch plan) | Nothing, or a stirrer that reaches the base |
| Oil-in to last jar in hours, several reheats, whole batch flatter than the test | Hold at heat | Prepare the bench before oil-in; split into two 10 kg batches | Nothing |
| Readings fine, last candles oily | Separation question | Diagnose it with the oily-last-candles post | Nothing yet |
The stakes justify the paperwork. At ₹221.30 of materials per candle (excluding labour, freight, packaging and GST), the 133-candle batch is ₹29,432.53, and the last third of it, about 44 candles, is ₹9,737.08. That last third is the part a bad pour window affects. When first-versus-last differences remain after the plan is in place, the first-weaker-than-last post charts pour position against blind scores.
What not to buy for a slow-cooling pot
What not to buy yet: a bigger melter (the 20 kg Electric Wax Melter is ₹25,960.00): a melter that holds the pot at temperature is useful, but it does not stir between draws or keep a pitcher warm, and its display needs checking against a thermometer (3276). A stronger oil to make up for a flatter late batch: the log will show whether the hold or the window is to blame, and a stronger oil at the same hold loses the same top. More oil: never go above the lower of the oil page's and wax page's maximum (Fallen Leaves 6–10%, CSI 464 up to 10%). Any purchase at all before one logged session: the log costs a sheet of paper.
We sell the pitcher, the mixer and the thermometer on this page. You may need none of them: a long spoon, one pitcher, the thermometer you own and a batch split into two 10 kg pots can give you the same consistency.
When the right purchase is nothing: if every last-jar reading was in the window and the draw groups match at the same cure age, your 20 kg pot is cooling slowly and doing no harm. Keep the log as the standard for every big session.
Pitcher, mixer, thermometer, wax and oil
Five items, in the order the session uses them. Chosen on page statements, price per unit or gram, and stock on 26 September 2026; CSI publishes no measured throw or cooling data, so nothing is ranked on performance. Pitcher and oil tables list every size, with out-of-stock sizes flagged.

tool · pouring · the unit the window is planned around
Steel Pouring Pitcher
In a 20 kg session the pot sets the starting temperature, but the pitcher sets the temperature at the jar. The page gives "Measurements: 12W x 13H Centimeters Capacity: 600 ml". A small mass of wax in thin steel cools far faster than the pot, so the question for each draw is whether its last jar is still in the window. Weigh a full pitcher once to know how many candles a fill pours; the worked example assumes 3 (450 g), which gives 45 draws for the batch. The Small (150 ml) is out of stock on 26 September 2026. Argued against our own interest: buy a second Large pitcher only if the log shows the pot waiting on the pitcher; one pitcher and a faster rhythm may be enough.
| Size | Price | Per unit | What it covers |
|---|---|---|---|
| Small (150 ML) | ₹354.00 — Out of stock | ₹354.00 | Out of stock |

tool · mixing · the restir before every draw
CSI Pro Mixer - Cordless Handheld Mixer for Candle, Diffuser & Soap Making
A big pot left alone for an hour is not the pot you stirred at the start: the wall and surface cool first, and a pot that is not stirred between draws can drift. A short, full-depth restir before every draw is the fix the window plan relies on. The captured page description holds no specifications beyond the title (no power, shaft length or speed), so check yourself that it reaches the bottom of your 20 kg pot, and keep the head submerged so it doesn't whip air into the wax. Argued against our own interest: a long steel spoon or paddle that reaches the base and walls does the same job; this is a convenience, not a requirement.

Every line of the cooling log is a reading: pot centre, pot wall, pitcher at the first jar and at the last. The page says it is designed to "monitor the temperature of your candle wax"; it states no range or accuracy in the text we captured, and it is the only thermometer CSI lists. For a 20 kg log, two readers (one for the pot, one for the pitcher) make the session easier. Argued against our own interest: any probe thermometer you trust works; check two against each other in the same wax before the session.

Luxury Soy Wax CSI 464 (Flakes Form) For Container Candles
The page states "Pour Temperature 80°C – 90°C" and "Fragrance Load Up to 10%". Those two numbers bound the whole window plan: the pot is held and reheated inside 80–90°C, never above, and in the 150 g jar rated "Safe for hot pour up to 85°C" the jar sees 80–85°C. A 20 kg batch at 8% of total weight is 1,600 g of oil and 18,400 g of wax, so two 10 kg bags (₹10,148.00) leave 1,600 g spare. Price is flat at ₹0.51 per gram from 1 kg to 10 kg. Argued against our own interest: if the log shows the pot drifting out of the window, a smaller batch, two 10 kg pots, costs nothing extra in wax and may be the simpler answer.

The page lists "Top Notes: Crisp Apple, Bergamot, Spicy Cinnamon Middle Notes: Dried Leaves, Rose, Jasmine Base Notes: Amber, Musk, Vanilla", describes its strength as "Medium to Strong" and states "Recommended fragrance load is 6-10% for candles". At 8% it sits inside both ceilings (its own 10% and CSI 464's 10%). It states no cure time in the text we captured. Every size is in stock on 26 September 2026. For 1,600 g: 1 kg + 500 g + 100 g costs ₹6,844.00; two 1 kg bottles cost ₹8,496.00 and leave 400 g. Argued against our own interest: the 500 g costs the same per gram as the 1 kg (₹4.25), so there is no need to overbuy for the batch; and a bright apple-and-bergamot top is exactly the part of a scent a long hold at heat tends to wear, so the log matters more than the bottle size.

The CSI principle
Pour the batch you tested: short, stirred and in the window.
A 1 kg test is poured in minutes. A 20 kg session has to be planned to behave the same way: restir before every draw, fills sized to the window, reheats only in range.
"The pot decides how long you have. The pitcher decides what the jar gets."

Why trust this guide
CandleMakingSuppliesIndia sells the pitcher, mixer, thermometer, wax and oil named here, and does not sell finished candles. This page still tells you that a long spoon may replace our mixer, that a second pitcher is only worth buying if the log shows the pot waiting, that two 10 kg batches cost nothing extra in wax or oil, and that a bigger melter is not the fix.
Every price and per-gram figure was verified on CSI's live store on 26 September 2026; every size shown in a pick table is in stock on that date unless flagged (the Small pitcher is out of stock). Temperatures, loads and pitcher dimensions are quoted from the product pages; the mixer's captured description holds no specifications, and we say so.
The effect ranking, the draw size, the restir time, the "differ" threshold and the 0–3 scale are editorial judgement; the cooling readings are a worked example; scale effects on mixing and scent are tendencies, while slower cooling of a larger mass is general physics.

Frequently asked questions
Why does a large batch of candle wax cool so slowly?
A big pot holds far more heat for the surface it loses heat through, so it cools much more slowly than a small test pot. The centre also stays hotter than the wall and surface unless you stir.
Can a big batch make my first and last candles different?
It can: longer hold at heat, an unstirred pot drifting between draws, and pitchers cooling before their last jar all tend to separate first from last. Log the pot and pitchers and retain candles from the first, a middle and the last draw.
How often should I stir a large pot of scented wax while pouring?
Before every pitcher draw, full depth, with the same short routine each time, reaching the base and wall and keeping the stirrer head under the surface. Time it and write it on your SOP.
Can I reheat soy wax during a long pouring session?
Yes, gently and only within the wax page's range: for CSI 464, 80–90°C, never above 90°C. Restir after reheating and log each reheat, because every one adds time at heat.
What temperature should the pitcher be when I pour into the jar?
Inside the lower of the wax page's range and the jar's rating. For CSI 464 in the 150 g Clear Glass Jar with Golden Lid, that is 80–85°C. Read the pitcher at its last jar, not just the first.
Is it better to make one 20 kg batch or two 10 kg batches?
If your log shows the 20 kg session running long, with several reheats or late jars out of the window, two 10 kg batches are simpler and cost the same in wax and oil. If the log stays in the window, one batch is fine.
Before your next 20 kg session
Log the pot, the wall and every pitcher, and pour to a planned window.
One logged session on a normal batch, with six candles retained by draw number, shows whether slow cooling is costing you consistency. Then fix it with the plan: fills sized to the window, a restir before every draw, reheats only in range. Send us your log on WhatsApp.

About this guide: part of CSI's cluster on the same formula giving a different result (3261–3280). It covers a 20 kg batch that cools much more slowly than the 1 kg test: why a big pot keeps its heat, a ranked differential table of session effects labelled as judgement, a pot cooling log (centre, wall, pitcher at first and last jar, draw numbers, retained candles), a pour-window plan (draw size, restir before every draw, reheats only within the wax page's range), a decision rule, and what not to buy. The oily-last-candles diagnosis (3227) and equipment qualification (3276) are linked, not repeated.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 on each card — Bamboo Stirring Sticks for Mixing Wax, Luxury Soy Wax Chunks for Jar / Container Candles, [1 Year Warranty] Mini Electric Wax/Soap Melter (1 litre capacity).

Non-price figures: load is a percentage of total candle weight (20 kg at 8% = 1,600 g oil + 18,400 g wax; 150 g at 8% = 12 g + 138 g). Temperatures and ceilings are as stated on the product pages (CSI 464 pour 80–90°C, up to 10%; 150 g jar hot pour up to 85°C; Fallen Leaves 6–10% for candles) and are formulation limits, not regulatory limits. The cooling readings, three candles per pitcher fill, the 30-second restir and the retained-candle groups are worked examples; the effect ranking and thresholds are editorial judgement; scale effects on mixing and scent are tendencies. Costs exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
