CSI Diagnostics · Burns Fast, Runs Hot
A candle that smells excellent has told you the formula works. If it burns fast and heats the jar, test one wick step down at the same load, scored by weight, heat and throw, before you reformulate anything.

Quick answers — read this first
Can I make the wick smaller without changing the fragrance load? Usually, yes, and it is the first thing to test. If the scent is already right, hold the oil and the load exactly where they are and change only the wick, one step down. The load stays out of it unless the smaller wick loses the melt pool.Why does it burn fast and heat the jar? In our judgement, most common first: a wick one size too big for this jar and oil, long burn sessions that let heat build, an untrimmed or carbon-capped wick, a draught or fan, then heat building in the final third. The fragrance oil and wax are the least likely suspects when the scent is right.
How do I test it? Pour four candles from one pot at your current load: two with your current wick (A), two one step down (B). Weigh every candle before and after each session for grams per hour, read jar heat with a non-contact thermometer (never by touch), and score throw blind at 1 hour and 3 hours.
What does it cost? Worked example at 8% in 150 g jars with Palo Santo and CSI 464: ₹977.23 of materials for all four candles, excluding labour, freight, packaging and GST. If you already own the oil, wax, jars and your current wick, the only new cash is ten Eco C1 wicks at ₹59.00.
The short answer
The rule: when the scent is right and the burn is wrong, fix the burn with the wick and leave the formula alone. One variable: wick size, one step down.
The test: A/B at a fixed load, two candles per arm from one pot, scored on grams per hour, jar heat at 1 h and 3 h, throw at 1 h and 3 h, and whether B still reaches a full pool.
The pass: B burns fewer grams per hour, reads cooler at 3 h, scores within one point of A on throw at 3 h, and still melts to the edge. Then switch wicks and keep the load.
The value: worked example, 7.5 → 5.5 g per hour turns 16.7 burn hours into 22.7, about 36% more for the same candle.

Burn hours per candle against grams burned per hour, drawn to scale. Hours = grams burned ÷ grams per hour; the worked example burns 125 g of a 150 g candle before the stop. The two points are illustrative rates for the current wick (A) and one step down (B), not CSI data. Near the top of the curve a small drop in rate buys a lot of hours, which is why weight, not the clock, is the measure.

Straight answer
My candle smells excellent but burns too quickly and the jar becomes hot. Can I reduce the wick size without completely reformulating the fragrance load?
Yes, in most cases, and you should try that before touching the formula. A candle that smells right has told you the oil, the load and the cure are doing their job; a candle that burns fast and runs hot is most often carrying a wick one size too big for its jar and oil. Keep the oil, the load (on the same total-weight basis) and the jar, and change only the wick, one step down. Prove it with an A/B: two candles on your current wick, two on the smaller one, poured from the same pot, weighed before and after every burn for grams per hour, jar heat read with a non-contact thermometer at 1 hour and 3 hours, and throw scored blind at the same times. If the smaller wick burns fewer grams per hour, reads cooler and stays within one point on throw at 3 hours while still melting to the edge, switch and keep the load. Only if the smaller wick loses the pool or the scent does the load come back into the question, and that is a different test (the three-arm step-down).
One line: the scent is your evidence that the formula works; test one wick step down at the same load, score it by weight, heat and throw, and reformulate only if the smaller wick fails.
The whole purchase for arm B: ten Eco C1 wicks for ₹59.00 (₹5.90 each), enough for the two test candles and a repeat. Every Eco pack size is in stock on 26 September 2026. If you already pour on C1, read the first pick card before buying anything.

Why a fast, hot burn is a wick question before it is a formula question
A candle that smells excellent has already passed the hardest test. Don't re-open it to fix a problem that lives in the wick.
Three separate things are happening in your candle, and they have separate owners. The scent comes from fragrance evaporating off the melt pool; it depends on the oil, the load, the cure and the pool being full. The burn rate is how many grams of wax and oil the flame consumes each hour; it depends mostly on how much fuel the wick draws up, which tracks wick size, trim length and how hot the pool runs. The jar heat is the glass absorbing heat from the flame and the pool; it rises with flame size, pool depth, session length and how far down the jar you are.
An oversized wick raises all three at once in the early burns: bigger flame, deeper pool, more fuel per hour, warmer glass, and often a strong throw, because a big hot pool releases a lot of fragrance. That is why "smells amazing but burns fast" is such a common pairing. The good scent and the bad burn can share a cause, and the fix for the burn may cost a little of the scent. The test on this page is built to measure exactly how much.
What the wick does not change is the formula. The oil in the pool is still the same percentage of the candle. Stepping the wick down changes how much of that pool is melted, how hot it runs and how fast it is consumed, and you judge the result on your candle, not on a rule. For the reverse question (a candle whose wick struggles because of a high load) see reduce fragrance or increase wick at 10%; for why a lower load can sometimes burn better, the 10% to 8% post. Neither is your situation if the scent is already where you want it.
Jar heat: measure it, never touch it
If you noticed the jar was hot by picking it up, stop doing that: a burning or just-extinguished candle jar can be hot enough to hurt, and touch is not a measurement. Use a non-contact (infrared) thermometer aimed at the same marked spot on the glass each time; CSI does not list one, so it is a hardware-shop purchase. Without one, rely on what you can see: flame height, pool depth, and how close the flame and pool sit to the glass. The 150 g jar page's "Safe for hot pour up to 85°C" is a pour figure, not a burning limit.What the fast burn looks like, and what each pattern points to
A fast burn from the first hour and a fast burn that only starts halfway down the jar are two different diagnoses.
The table ranks the usual patterns behind "burns fast, jar hot, smells great", most common first. The ranking is editorial judgement; CSI publishes no failure statistics. The right-hand columns are what you can observe to rule each cause in or out, and most of them come from the burns you have already done.
Differential table · fast burn, hot jar, good scent
Ranked most common first (judgement) · every rule-in and rule-out is an observation
| # | Pattern you observed | Likely cause | Rules it in | Rules it out |
|---|---|---|---|---|
| 1 | Pool reaches the edge well inside the first 2 hours and keeps deepening; tall, busy flame from the first burn | Wick one size too big for this jar and oil | Pool deeper than about 1 cm by the end of a 3-hour burn (rule of thumb); fast from the top of the jar | Pool reaches the edge at about 3–4 hours and sits about 0.5–1 cm deep |
| 2 | Burns are fine for 2–3 hours, then the flame and heat climb | Session length: heat accumulating in long burns | Weight lost in hour 4 onwards is higher than in hours 1–3 | Rate is high from hour 1 |
| 3 | Flame grows between trims; a black carbon cap forms | Untrimmed wick or carbon build-up | A twin trimmed before every burn runs slower and calmer | Trimmed and untrimmed twins burn alike |
| 4 | Flame leans or flickers; one side of the pool races ahead | Draught, fan or AC vent, or a wick off-centre | Same candle burns slower in a still corner; wick visibly off-centre | Still room, centred wick, same result |
| 5 | Fine in the top half, fast and hot only in the lower third | Heat building as the level falls | Grams per hour rising burn by burn (the weigh-per-burn log) | Rate flat from top to bottom |
| 6 | Started after a change of wax, wick lot or jar | The new material, not the wick size as such | Retained candles from before the change burn slower | Retained candles burn the same |
Patterns 2 to 5 do not need a new wick. A shorter session, a trim, a still spot and a centred wick cost nothing, and they are worth ruling out on one candle before you pour the A/B, because they would contaminate it. Pattern 5 is its own problem, handled in the late-burn cluster; if your weights only climb near the bottom, start at the flame-growth hub and the final-third acceptance grid. Pattern 1, fast from the very first burn, is what the rest of this page tests.
Mistake: reading a huge flame, a deep pool and soot as the same problem as a fast, hot burn. Why it matters: soot and smoke add a combustion question (trim, draughts, carbon), and they change what you must score. Fix: if soot or a smoking flame is part of your picture, use the soot-and-huge-flame step-down, which rates soot and throw at fixed distances; if the pool looks perfect but the flame smokes, the seven-criterion scorecard. This page assumes a clean flame that is simply too hungry.
The A/B step-down at a fixed load
Four candles, one pot, one variable. The wick is the only thing allowed to differ.
The design is deliberately small. Two arms: A is your current wick, B is one step down in the same wick family (for Eco wicks, C2 to C1). Two candles per arm, because one candle can mislead you and two that agree cannot so easily. All four come from a single pot, so oil, load, wax, add and pour temperatures and cure age are identical by construction.
The pot and what it costs (worked example)
Four 150 g candles at 8% of total weight is 600 g: 48 g of oil and 552 g of wax. With Palo Santo (page range "Up to 10% for soy wax") in CSI 464 (page "Fragrance Load Up to 10%"), 8% sits inside both ceilings; if your own load is higher, keep it, as long as it is within the lower of your oil page's and wax page's stated maximum. A 50 g bottle leaves 2 g after the pot, so buy the 50 g only if you are not already using this oil.

Running it
1
Pour, label, cureWick all four jars before pouring (two A, two B), centre them the same way, pour from one pot and label the bases A1, A2, B1, B2. Let them cure at least as long as your oil page states (Palo Santo's page says 48–72 hours for soy); many makers start burn tests at day 7. All four are the same age, so cure cannot favour either arm.
2
Fix the sessionEvery session is 3 hours, lit and extinguished by the clock, wicks trimmed to the same length before each light (the trimmer page's tip is "Trim your wick to 1/4 inch before every burn"). A 3-hour session is inside the common-practice cap of about 4 hours and long enough for the 1-hour and 3-hour readings. Burn within sight, on a heat-safe surface, away from fans and vents.
3
Weigh before and afterWeigh each candle before lighting and again once it has cooled and set, on a scale that reads single grams. Session loss ÷ 3 = grams per hour. In the worked example, A loses about 22.5 g a session and B about 16.5 g; your numbers will differ, and they are the only ones that count.
4
Read jar heat at 1 h and 3 hMark one spot on each jar, about a third of the way down from the rim, and read it with a non-contact thermometer from the same distance at 1 hour and 3 hours. Record the numbers; you will compare A against B, not against any "safe" figure, because CSI states none for burning. No thermometer: record flame height against a ruler held behind the jar, and pool depth with a skewer dipped at the end of the session.
5
Score throw at 1 h and 3 h, one candle at a timeFor the first two sessions of A1 and B1, burn them on alternate evenings in the same closed room, never together (four evenings). At 1 hour and 3 hours, walk in from outside and score 0 (nothing), 1 (only within a metre), 2 (noticeable across the room), 3 (fills the room); ideally a second person who does not know which arm is lit. A2 and B2 burn in another room at the same times, for weights and heat only. After those four evenings, all four can burn side by side, a metre apart.
6
Burn to the stop and total the hoursKeep going, session after session, until about 1 cm of wax is left (common practice), then add up the hours per candle. Worked example: with 125 g to burn, A needs about 5.6 sessions and B about 7.6. That total is the burn-hours figure your customer experiences, and it takes the final third into account without this page having to diagnose it.
Mistake: changing the wick and the load together "to save a round". What it does: if B burns slower and smells weaker, you cannot tell whether the wick or the oil cost you the scent, and you have reformulated a candle whose scent you liked. Fix: this A/B changes the wick only. The wick-plus-load arm exists, within the ceiling, in the three-arm step-down; run it only if B fails on throw.
Reading the four scores together
No single score decides it. A cooler candle that tunnels or loses its scent has not passed.
You now have, per candle, grams per hour for every session, heat readings (or flame and depth notes) at 1 hour and 3 hours, throw scores at 1 hour and 3 hours from the first sessions, and total burn hours. Average the two candles in each arm; if the pair in one arm disagree by more than the gap between arms, repeat rather than decide.
Decision rule · A (current wick) vs B (one step down), same load
Throw scores 0–3 on entering · "within one point" = B no more than 1 below A at 3 hours · full pool = liquid to the glass by about hour 3–4 (rule of thumb)
| What you see | What it means | Decision | Purchase |
|---|---|---|---|
| B: fewer g/h, cooler at 3 h, throw within one point at 3 h, full pool | A was oversized; B carries the formula without the excess | Switch to B; keep the load; confirm with one full burn-down in your production jar | C1 in production packs |
| B: fewer g/h and cooler, but throw drops two points or more at 3 h, pool full | The extra heat was carrying the throw | Decide on value: longer burn and lower throw, or keep A with shorter sessions; if neither, the wick-plus-load arm | Nothing yet |
| B: fewer g/h but pool short of the edge at 3–4 h | B is too small for this jar; the right wick sits between the two | Keep A and manage sessions, or weigh the first-burn trade-off (slow first pool vs oversized) | Nothing |
| B burns no slower than A | Wick size is not what drives the rate | Go back to patterns 2–6: sessions, trim, draught, centring, final third | Nothing |
| Both arms fine at the top, both racing in the final third | Heat build-up with depth, not the starting wick | Late-burn cluster: weigh-per-burn, final-third criteria | Nothing yet |
Notice where the throw is scored. The 1-hour reading shows how quickly each candle gets going; a smaller wick often lags early, which customers mostly forgive. The 3-hour reading is when a full pool should be doing its work, and that is the one the pass rule uses. If B matches A at 3 hours, the early lag is a price worth paying for the extra hours. Scores at 1 metre and at fixed distances are 3282's method; here a walk-in score is enough, because the question is "did we lose it?", not "how far does it reach?".
Why weight beats the clock
Timing a candle to its end tells you one number at the finish, weeks later, and mixes in every long session and draught along the way. Weighing each session gives you a rate within the first evening and a trend over the whole jar, and it separates "burns fast from the start" (a wick size question) from "burns fast only later" (a depth question). The same method, applied down the jar, is the weigh-per-burn log; here it compares two wicks.Burn hours per candle: what the customer is paying for
Your customer never sees grams per hour. They notice that the candle ended sooner than they expected.
Grams per hour is your measurement; burn hours per candle is the customer's. The chart at the top shows how the two relate: hours = grams burned ÷ grams per hour. The curve is steep at the fast end, so a modest drop in rate buys a lot of time. In the worked example, going from 7.5 to 5.5 g per hour (27% fewer grams per hour) takes the candle from 16.7 to 22.7 hours, about 6.1 hours or 36% more, with the same oil, the same load and the same jar.
Material cost per burn hour · worked example
150 g candle at 8%: 12 g Palo Santo (₹6.02/g) + 138 g CSI 464 + 150 g jar + wick · 125 g burned · excludes labour, freight, packaging and GST
| Arm | Materials per candle | Worked-example rate | Burn hours | Material cost per burn hour |
|---|---|---|---|---|
| A · current wick (C2) | ₹246.08 | 7.5 g/h | 16.7 | ₹14.76 |
| B · one step down (C1) | ₹242.54 | 5.5 g/h | 22.7 | ₹10.67 |
Two things change for the better at once. The candle costs ₹3.54 less to make, because C1 is cheaper than C2 (₹5.90 against ₹9.44; across 100 production wicks that is ₹354.00), and it delivers more hours, so the material cost per burn hour falls by ₹4.09. The rates are illustrative; put your own measured grams per hour into the same sum. If you print a burn time on your label, base it on your own full burn-downs in the production jar, sessions of the length your care card recommends, and round down.
Honest limit: burn hours are not the only value. A customer who bought the candle for a strong living-room scent may prefer A's bigger throw, and fewer hours, to B's longer, gentler burn. That is a product decision, not a diagnosis. The A/B gives you the numbers for both sides; the choice depends on who buys the candle and what they are told on the label. Either way, a jar that gets dangerously hot is not a choice: if the final third fails the acceptance criteria in the hot-jar-near-the-bottom post, the wick changes whatever the throw.
What not to buy for a hot, fast burn
The commonest fix here costs ₹59.00. Most of what people buy instead changes something that was working.
What not to buy: a different fragrance oil, or a big bottle of one. The scent is the part that works; a new oil re-opens throw, cure and possibly wick fit. Less oil as a first move: lowering the load changes the scent you liked and may change the burn little, because wick size drives fuel draw far more directly. Prove the wick first. A heavier or "heat-resistant" jar: thicker glass does not reduce the flame, a heavier jar is not automatically safer, and a jar change adds a second variable (for when the jar itself is the question, is the jar unsafe or the wick too large?). Additives such as Vybar or microcrystalline wax to "slow" the burn: their pages make claims about fragrance retention, hardness and surface, not burn rate, and any additive changes how the wick draws, which means re-testing the wick anyway. A bigger wick "for a cleaner burn": a hotter, faster burn is the symptom, not the cure.
What the test does need is short: the next wick down, a scale you trust, and a way to read the glass that is not your hand. A non-contact thermometer is the one tool here that CSI does not sell; we would rather you buy one elsewhere than guess by touch.

wick · arm B · the step-down under test
Eco Candle Wicks — Thin (C1)
If your current wick is the Eco Thick (C2), the Thin (C1) is the one step down inside the same range, same fibre, same tab: the cleanest single-variable change you can make. The page describes wicks made from "natural fibers like cotton and paper" that "pair perfectly with soy wax"; it states no size-to-jar chart, so C1 is a rung to test, not an answer. Every pack size is in stock on 26 September 2026 and the price per wick is flat (₹5.90 for C1, ₹9.44 for C2 at every pack), so the pack of 10 is the right test buy. Argued against our own interest: if C1 is already your wick, the Eco Candle Wicks listing has no thinner size; it offers two, C1 and C2. Your step-down is then outside our range, or a change of jar or fill height (the options table).
| Size | Price | Per unit | What it covers |
|---|---|---|---|
| Thin (C1) / 10 | ₹59.00 | ₹5.90 | arm B of the A/B with eight spare for a repeat |
| Thin (C1) / 100 | ₹590.00 | ₹5.90 | production, once C1 has passed a full burn-down |
| Thick (C2) / 10 | ₹94.40 | ₹9.44 | arm A, if your current wick is C2 and you have none left |
| Thick (C2) / 100 | ₹944.00 | ₹9.44 | what you would stop buying if C1 wins |

jar · the test vessel with a stated pour figure
Clear Glass Jar with Golden Lid (150 gram)
Clear glass lets you watch what the grams-per-hour number is telling you: pool depth against the wall, a flame leaning towards one side, a wick that has drifted. The page lists an outer diameter of about 7 cm and "Safe for hot pour up to 85°C". Read that carefully: it is a pour figure, the temperature of wax going in, not a rating for how hot the glass may get during a burn, and it says nothing about your wick. With CSI 464 (pour 80–90°C on its page) pour at 80–85°C in this jar. Flat ₹94.40 per jar at both pack sizes. Limitation: if your weak point is a different jar, test in that jar, because a wick verdict does not transfer between jars (the 7 cm to 8 cm question).

jar · if this is the jar your candle lives in
Black Matte Glass Jar
The page gives "Height 8 cm width 7 cm" and "a fill weight of 200 ml", and says its durability "allows it to withstand high heat". That last line is general wording, not a temperature, so treat it as no rating at all and apply the same rule as any jar: flame never near the glass, stop with about 1 cm left, never judge the glass by touch. The listing mentions no lid. A 200 ml fill is not 200 g of wax: a common rule of thumb puts it near 172 g–180 g, and a weighed test pour to your own fill line settles it. Argued against our own interest: do not buy this jar to cure a hot burn. Opaque black glass hides the pool and the soot you need to see during the A/B, and a jar swap is a second variable. Run the test in the jar you sell. ₹70.80 a jar at both pack sizes, ₹23.60 less than the clear 150 g jar.

tool · grams per hour lives on the scale
Candle Making Weighing Scale
The A/B is scored on weight: the candle weighed before and after every session, the difference divided by the hours burned. The page describes a digital scale showing "grams or ounces" with "simple one-button operation"; it does not state capacity or reading step, so check that a full jar sits on it and reads single grams before you trust a 16.5 g session loss. Argued against our own interest: any kitchen scale that reads single grams and carries a filled 150 g jar does this job. If you own one, skip this.
| Size | Price | Per unit | What it covers |
|---|---|---|---|
| Single | ₹354.00 | ₹354.00 | before/after weights for grams per hour (capacity and reading step not stated) |

Palo Santo Fragrance Oil
The worked example in this guide is a candle whose scent the maker is happy with, so the oil is not under test. Palo Santo suits the example because its page is unusually specific: "Recommended Fragrance Load: Up to 10% for soy wax", cure "48–72 hours for soy wax", and "Wick Recommendations: Eco wicks or wooden wicks for an even, clean burn. Wick testing is recommended based on your container and wax type." It describes "Earthy palo santo with soft citrus, warm amber, and a touch of incense". Every size is in stock on 26 September 2026. Argued against our own interest: from 50 g to 1 kg the price is flat at ₹6.02 a gram, so a bigger bottle saves nothing per gram; and if your own oil already smells excellent, buy none of this and run the A/B with the oil you have.
| Size | Price | Per gram | 150 g candles at 8% |
|---|---|---|---|
| 15 g | ₹106.20 | ₹7.08 | 1 |
| 50 g | ₹300.90 | ₹6.02 | 4 |
| 100 g | ₹601.80 | ₹6.02 | 8 |
| 500 g | ₹3,009.00 | ₹6.02 | 41 |
| 1 kg | ₹6,018.00 | ₹6.02 | 83 |
One candle at 8%: 12 g = ₹72.22. Buy 50 g — ₹300.90
Diwali is 8 November 2026, 43 days from 26 September 2026. A 7-day cure plus about ten evenings of 3-hour sessions is roughly 17 days, leaving about 26 days to pour on the winning wick. Send us your candle count and we will quote C1 wicks, wax and jars with a GST invoice and a dispatch date.

The CSI principle
When the scent is right and the burn is wrong, change the part that burns.
One wick step, same pot, same load. Weigh it, read the glass without touching it, score the throw at 3 hours, and let burn hours per candle settle the argument.
"A wick that is one size too big often makes a candle smell wonderful for half its life. The customer pays for the other half."

Why trust this guide
CandleMakingSuppliesIndia sells the wicks, wax, jars and oils named here and does not sell finished candles. This page still tells you not to buy a new oil or jar for this problem, that the Eco Candle Wicks listing has no size smaller than C1, that a kitchen scale will do, and that the one tool you need most, a non-contact thermometer, is not something we sell.
Every price and per-unit figure was verified on CSI's live store on 26 September 2026; every size in the pick tables is in stock on that date, and the tables are built to flag any size that is not. Load, cure, pour and wick wording is quoted from the product pages; where a page is silent in the text we captured, we say so.
The cause ranking, the 3-hour session, the 0–3 throw score, the "within one point" pass rule and the grams-per-hour rates in the chart are editorial judgement or worked examples, not CSI data; melt-pool times and depths are commonly cited rules of thumb. For bulk pricing, GST invoicing, and MSDS and IFRA documentation on request, message us on WhatsApp at +91 7397976926.
Frequently asked questions
Why does my soy candle burn so fast?
Most often, in our judgement, the wick is one size too big for the jar and oil, so it draws more fuel than the candle needs. Long sessions, an untrimmed wick, draughts and heat building near the bottom of the jar also speed it up. Weigh the candle before and after a 3-hour burn to get a rate you can compare.
Can I use a smaller wick without changing the fragrance load?
Usually yes. Pour two candles on your current wick and two one step down from the same pot at the same load, and compare grams per hour, jar heat and throw at 1 and 3 hours. If the smaller wick still reaches a full pool and scores within one point on throw at 3 hours, keep the load and switch wicks.
How hot should a candle jar get while burning?
CSI jar pages do not state a burning temperature limit; the 150 g jar's "Safe for hot pour up to 85°C" is a pour figure. Compare readings between wicks with a non-contact thermometer at a marked spot, never by touch, and fail any wick whose flame reaches the glass or whose final third runs hot.
Will a smaller wick reduce hot throw?
It can, a little, especially in the first hour, because a smaller flame melts the pool more slowly. What matters is the score once the pool is full. Score throw blind at 1 hour and 3 hours; if the smaller wick is within one point of the current wick at 3 hours, most customers will not notice the difference.
How do I calculate candle burn time?
Weigh the candle before and after each burn and divide the weight lost by the hours burned to get grams per hour. Burn hours are roughly the grams you will burn before stopping with about 1 cm left, divided by that rate. Worked example: 125 g at 5.5 g per hour is about 22.7 hours.
What is the difference between Eco C1 and C2 wicks?
They are the Thin (C1) and Thick (C2) sizes of CSI's Eco Candle Wicks, made from cotton and paper fibres for soy wax. C1 is ₹5.90 and C2 ₹9.44 per wick at every pack size. The page states no jar-size chart, so test them as neighbouring rungs in your own jar.
Before you touch the formula
Test one wick step down at the same load: ten Eco C1 wicks cost ₹59.00.
Pour two candles on your current wick and two on C1 from one pot. Weigh every session, read the glass with a non-contact thermometer, score throw at 1 hour and 3 hours, and total the burn hours. Send us the numbers on WhatsApp and we will tell you what they point to.
