Candle Performance Guides · Burn Rate Measurement
You need three numbers and a clock: the whole candle's weight before a session, its weight after, and the minutes it burned. Everything else on this page is about making those three numbers trustworthy enough to make decisions with.
±0.25 g/h
the uncertainty a scale reading to the nearest gram leaves on a four-hour weigh-pair — the same scale over a one-hour session leaves ±1 g/h, four times worse · tools from ₹354, CSI live pricing, September 2026
Quick answers — read this first
What is the formula? Burn rate = (weight before − weight after) ÷ hours burned. Weigh the entire candle — glass, wax, wick, lid off and set aside the same way every time — on the same scale, in the same spot. A 150 g jar candle that went from 352.4 g to 315.6 g over 4.0 hours consumed 36.8 g, which is 9.2 g per hour.How long should the session be? Long enough that the scale's error disappears. A scale reading to the nearest gram puts about ±1 g of uncertainty on the difference between two readings. Over one hour that is ±1 g/h — nearly 11% of a 9.2 g/h result. Over four hours it is ±0.25 g/h, under 3%. Burn in three- to four-hour sessions and the arithmetic stops arguing with you.
What do I need to buy? One weighing scale at ₹354 and a clock you can read to the minute. A pen thermometer at ₹354 is for the pour, not the burn, but you need it to make the candle repeatable in the first place.
Does CSI publish a figure I can compare against? No. No CSI wax, wick or jar page publishes a burn time or a consumption rate, and this guide does not estimate one. That is exactly why the measurement is worth running: the number is a property of your candle, not of any ingredient in it.
The short answer
Weigh the whole unit, not the wax: you cannot weigh wax inside a glass, so weigh glass and wax together and let the glass cancel out in the subtraction. The jar's weight is in both readings, so it is in neither answer.
Time the burn, not the evening: write the start and stop times to the minute. "About four hours" and 4.0 hours differ by enough to move your result by several percent.
Make the session long and the handling identical: three to four hours, lid off and parked in the same place, wick trimmed before the weigh-in and the trimmings thrown away before you weigh.
In this guide
Three readings produce one rate. The glass, the wick tab and the wick sticker are present in both weighings, so they contribute nothing to the subtraction — which is why you never have to know what the empty jar weighs.

How do I measure grams of wax consumed per hour during a candle burn test?
Put the whole candle on a scale, note the weight and the time, burn it for a timed session of three to four hours, blow it out, let it cool until the pool is solid, and weigh the whole candle again. Grams lost divided by hours burned is your burn rate. In the worked example above, a cured 150 g jar candle weighing 352.4 g with the lid off came back at 315.6 g after exactly 240 minutes: 36.8 g consumed, 9.2 g per hour. You never weigh the wax on its own and you never need the empty jar's weight, because the glass sits in both readings and cancels in the subtraction. The two decisions that actually determine whether the number is any good are session length and handling consistency. A ₹354 scale that reads to the nearest gram leaves roughly ±1 g of uncertainty on the difference, which is ±1 g/h over one hour but only ±0.25 g/h over four — so short sessions are where measurement noise lives. Handling means the lid comes off and goes to the same place, the wick is trimmed before the weigh-in with the trimmings binned, nothing is topped up, and the candle is cool and dry at both weighings. Cure first: the Luxury Soy Wax Chunks page asks for a minimum of 48 hours and ideally one to two weeks before burn testing. One rate from one session is a measurement; a candle's rate comes from logging every cycle of a full life.
One line: weigh the whole candle, burn it for a timed three to four hours, weigh it again, divide grams lost by hours — and make the session long so the scale's last digit stops mattering.
Everything this measurement needs from a supplier: a Candle Making Weighing Scale at ₹354, a Pen Thermometer at ₹354 so the pour is repeatable, and a wax whose page states its own add and pour temperatures — Luxury Soy Wax Chunks from ₹299 for 500 g.

The four numbers, and why the jar cancels
A burn rate is subtraction. Most bad burn rates are bad subtraction.
Candle makers get stuck on this measurement because the thing they want to weigh is sealed inside a glass. You cannot put 150 g of wax on a scale once it is a candle, and you certainly cannot weigh the molten part. So people guess: they measure the pool depth with a skewer, they compare the wax line against a mark on the glass, they time the hours until it dies and divide the fill weight by that. All three are proxies, and all three mix the thing they want to know with something else.
The weigh-pair sidesteps the problem entirely. Put the complete candle on the scale — glass, lid off, wax, wick, wick tab, sticker, label and all. Burn it. Put the complete candle back on the same scale. The only part of that assembly that changed is the wax and fragrance that burned away. The glass weighs what it weighed. The tab weighs what it weighed. So the difference between the two readings is the mass that left the candle up the flame, and nothing else.
The four numbers · worked example of the method
What you write down, and what each number is for
| Number | Example | How it is taken | What goes wrong if you skip it |
|---|---|---|---|
| Weight before | 352.4 g | Whole candle, cold, lid off, wick already trimmed | A warm jar, a lid left on or an untrimmed wick all land in the wrong reading |
| Start time | 18:04 | Written to the minute when the wick catches | "About six" becomes a 10-minute error — 4% of a 4-hour session |
| Stop time | 22:04 | Written to the minute when you snuff it | Same error, doubled, and it always flatters a fast candle |
| Weight after | 315.6 g | Same scale, same spot, once the pool is solid again | Weighing it hot risks a burn and loses wax to drips and handling |
| Derived: consumed | 36.8 g | 352.4 − 315.6 | — |
| Derived: hours | 4.00 h | 240 minutes ÷ 60 | — |
| Derived: burn rate | 9.2 g/h | 36.8 ÷ 4.00 | — |
Worked out above: 352.4 g − 315.6 g = 36.8 g. 18:04 to 22:04 = 240 minutes = 4.00 h. 36.8 ÷ 4.00 = 9.2 g/h. These weights are an illustration of the arithmetic on a 150 g jar candle in a glass of ordinary weight — they are not a published figure for any CSI wax, wick or jar, because no CSI product page states a burn time or a consumption rate.
Notice what the method does not require. It does not need the empty jar's weight, the exact fill weight, the fragrance load, or any specification from the product page. Those matter enormously for deciding what to change — but they are not inputs to the measurement. This is the reason the weigh-pair works on a candle you poured last month and forgot to document: the subtraction still tells you the truth about how fast it is going.
The mistake: dividing fill weight by total hours. It is the most common shortcut and it answers a different question. Fill ÷ hours gives you an average that silently assumes every gram you poured got burned — and almost no container candle finishes empty. If a 150 g candle ran 18 hours and stopped with 11 g stuck to the glass, fill ÷ hours says 8.33 g/h while the honest figure is 139 ÷ 18 = 7.72 g/h, an 8% error that grows with every gram the candle leaves behind. The leftover-wax correction has its own guide in this series: should remaining wax be subtracted when calculating usable burn efficiency.
The scale: what the page states, what you verify yourself
CSI's Candle Making Weighing Scale is listed at ₹354, and what its product page states is simple: it "shows measurements in grams or ounces". The page does not state a maximum capacity and it does not state a resolution. We are not going to invent either. What you do instead takes two minutes and makes the rest of this page work regardless of which scale you own.
1
Find the smallest step your scale will showSwitch it to grams. Put something light on it and add small items one at a time. Whether the display moves in steps of 1 g, 0.5 g or 0.1 g is your resolution, and it is the number that drives the session-length table below. Write it on a sticker on the scale.
2
Check it reaches your heaviest candleA 500 g candle in a heavy glass with a lid can approach a kilogram. Load your largest filled jar and confirm the scale reads it rather than flashing an overload warning. If it will not, the measurement still works — but only on your smaller sizes, and you should say so in your records.
3
Test repeatability, which matters more than accuracyWeigh the same candle five times, lifting it off and replacing it between readings. If all five agree, you can trust a difference of a few grams. If they wander by 3 g, your weigh-pair carries 6 g of noise and you need longer sessions or a better surface. A scale that reads consistently 4 g heavy is still perfectly useful here, because a constant offset cancels in a subtraction.
4
Fix the spotHard, level surface. Not the edge of a table, not a cloth, not next to a running fan. Mark the spot with tape and use it for every weighing of every test candle for the rest of the project.
5
Decide your lid rule and never change itLid off and parked on the shelf is the simplest rule because the lid never enters a reading. Lid on at both weighings works too. What ruins a data set is a lid that is sometimes on and sometimes off — on a heavy metal lid that is a double-digit swing in grams, dwarfing everything the flame did.
Why a cheap scale is enough for this job
Burn rate is a difference, and differences forgive the thing cheap scales are bad at. Calibration error — reading everything a few grams high — subtracts itself away completely. What a difference does not forgive is random scatter, because that adds up across two readings. So when you test the scale, you are not checking whether it tells the truth; you are checking whether it tells the same story twice. For the wider tool kit, CSI's candle tool guide covers what else earns a place on the bench.How long a session has to be before the number means anything
This is the part most burn-test instructions skip, and it is the difference between a figure you can set a specification against and a figure that changes every time you repeat it. Both of your weighings carry uncertainty of about half the scale's smallest step, so the difference carries roughly a full step. That fixed grams of doubt gets divided by your session length — which means session length is a dial that controls your error directly.
Session length versus measurement noise · 1 g resolution, 9.2 g/h example
What one gram of scale doubt and five minutes of clock slop do to your result
| Session | Grams consumed at 9.2 g/h | ±1 g becomes | As % of the rate | ±5 min of timing error | Verdict |
|---|---|---|---|---|---|
| 1.0 h | 9.2 g | ±1.00 g/h | ±10.9% | ±8.3% | Noise, not a measurement |
| 2.0 h | 18.4 g | ±0.50 g/h | ±5.4% | ±4.2% | Rough indication only |
| 3.0 h | 27.6 g | ±0.33 g/h | ±3.6% | ±2.8% | Workable minimum |
| 4.0 h | 36.8 g | ±0.25 g/h | ±2.7% | ±2.1% | The sweet spot |
| 6.0 h | 55.2 g | ±0.17 g/h | ±1.8% | ±1.4% | Tighter, but a long sitting |
| 8.0 h | 73.6 g | ±0.13 g/h | ±1.4% | ±1.0% | Diminishing returns |
Worked out above: grams = 9.2 × hours. Scale term = 1 g ÷ hours, expressed as a percentage of 9.2 g/h. Timing term = 5 minutes ÷ (60 × hours). Both assume a scale resolving to 1 g; if yours resolves to 0.1 g, divide the scale column by ten and the clock becomes your dominant error instead. Nothing in this table is a figure for a CSI product — 9.2 g/h is the worked example's own result.
Two conclusions fall straight out. First, three to four hours is the shortest session worth recording, and that happens to sit inside the burning window most candle care instructions already recommend — so you are not distorting the test to suit the maths. Second, once you get past four hours the scale stops being your limiting factor and the clock takes over. At that point the cheap improvement is not a better scale; it is writing the start and stop time to the minute instead of to the nearest quarter hour.
Do not bank a session you cut short. The temptation is to snuff the candle at two hours because dinner is ready, then write "≈2 h" and keep the row. That row carries twice the noise of your four-hour rows and it will sit in your average pretending to be equal to them. Either record the exact minutes and flag the row as short, or treat it as a burn that happened and simply log the weight change against the real time — never round a session to a convenient number. The discipline for stringing these rows into a full life is in weighing before and after every burn cycle.
The weigh-pair protocol, start to finish
Here is the whole thing as a bench procedure. It assumes a cured candle: the Luxury Soy Wax Chunks page asks for a minimum of 48 hours and ideally one to two weeks before burn testing, and a candle measured before it has cured is measuring the cure, not the wick. CSI's 14-day cure guide explains why.
1
Trim first, then weighTrim the wick to your care-instruction length before the candle goes on the scale, and bin the trimmings away from the bench. Trim after the weigh-in and you have removed mass the flame did not consume, which lands in your result as wax that never existed.
2
Weigh-in and write four thingsCandle ID, weight, clock time, and the room — temperature if you have a thermometer, otherwise "front room, windows shut". Draught is the single biggest uncontrolled variable in a burn test and you want to be able to blame it later.
3
Light it and start the clock at the same momentNote the minute the wick is properly alight, not the minute you picked up the lighter. Set an alarm for the end of the session so the duration is decided in advance rather than by whenever you remember.
4
Leave it alone, and watch itNo repositioning, no lid, no draught, no rescue of a leaning wick. Note flame behaviour at the half-hour marks and anything that would disqualify the candle on safety — a flame that climbs, a jar too hot to hold, soot on the glass. A rate measured on an unsafe candle is a number describing something you will not ship; see candle flame too high.
5
Snuff at the alarm and record the minuteSnuff rather than blow, so nothing is sprayed out of the jar. Then leave the candle on the bench until the pool has set solid and the glass is cool to the touch — the weight will not change while it cools, but your hands and the jar both prefer it, and a solid surface cannot drip.
6
Weigh-out, subtract, divide, logSame scale, same taped spot, lid still off. Write the weight, do the two sums, and put the rate in the row next to the session. Then read it against your previous sessions on the same candle rather than against anyone's published figure, because there isn't one.
Run three candles, not one
Pour at least three identical units from the same batch and give each its own weigh-pair in the same session. Three rates from one evening tell you something a single candle cannot: how much your own pouring and wicking vary. If the three agree within a few tenths of a gram per hour, your process is repeatable and one candle is enough next time. If they do not, the spread is your real measurement uncertainty — and it is almost always larger than the scale's. The claim-setting end of this problem is covered by how many full-life tests to complete before publishing a claim.Seven things that corrupt a weigh-pair
Every one of these has the same signature: a rate that looks wrong and will not repeat. They are listed by how much damage they do to a 150 g candle burning at roughly 9 g/h, where the whole session only moves the needle by 37 g — so a 10 g mistake is a quarter of your signal.
Error sources, ranked by damage
What it does to the reading, and the fix
| What happened | Effect on the measured rate | Fix |
|---|---|---|
| Lid on at one weighing, off at the other | Can swing the difference by tens of grams — bigger than the burn itself | One lid rule, written at the top of the log sheet |
| Wick trimmed between the two weighings | Inflates consumption by the mass of the trimmings | Always trim before the weigh-in |
| Topping up or re-pouring a sinkhole mid-test | Adds mass; the rate can even come out negative | Never alter a test candle; fix the pour, repour the batch |
| Session timed to the nearest half hour | Up to ±12% on a two-hour session, ±6% on four | Clock times to the minute, both ends |
| Weighing while the pool is still liquid | Drips and smears lose real grams off the jar | Wait for a solid surface and a cool glass |
| Wax or soot wiped off the glass before weighing out | Removes mass the flame did not burn | Clean the glass after the weigh-out, never before |
| Scale moved to a different surface | Adds scatter to both readings, so double the error | Tape the spot and leave the scale on it |
The sneakiest one: comparing a fresh candle to a half-burnt one. A weigh-pair taken on the first session of a brand-new jar and a weigh-pair taken halfway down the same jar are both valid measurements — of different things. The flame sits lower in the glass as the candle goes down, the glass is warmer on its outside, and the pool shape changes. If you want one number for the candle, you have to sample the whole life, which is why this series separates the top, middle and bottom of a jar into separate top, middle and bottom consumption rates. Never compare a cycle-one rate on one SKU against a mid-jar rate on another and conclude anything.
The CSI principle
A burn rate is not a property of your wax. It is a property of your candle, and only your scale knows it.
We publish the price, the pack, the stated load and the stated pour temperature of every wax we sell. We do not publish burn hours or grams per hour, because the same kilo of wax in two different jars with two different wicks is two different candles. The measurement is yours to take — and once you have taken it, no supplier's claim can be used against you.
Reading your number — and what it is not
You now have a figure like 9.2 g/h. Three things it is: a comparison tool between your own SKUs, an input into hours when you multiply it against the wax a candle actually gives up, and an early-warning signal when a batch or a supplier changes. Three things it is not: a benchmark, a quality score, and a number that transfers to a different jar.
What one session's rate can and cannot support
From one weigh-pair to a decision — and where you need more than one
| Question you want to answer | Is one weigh-pair enough? | What it actually takes |
|---|---|---|
| Did my candle get faster after I changed wax supplier? | Almost — if both candles were measured the same way, in the same jar, at the same stage | One weigh-pair each on three units, same session, one variable changed |
| Which of my two wick options should I ship? | No | Full-life testing on both, because a wick that behaves at the top can fade lower down |
| How many hours will my customer get? | No | Usable wax ÷ rate, where usable wax excludes what the candle leaves behind |
| Is 9.2 g/h a good number? | No — and nor is a hundred weigh-pairs | Nothing published answers this; you judge it against your jar, your fill and your own other SKUs |
| Can I print a burn time on the label? | No | Repeat full-life tests on more than one unit, then a conservative figure or a range |
That fourth row is the one people resist. There is no published appropriate rate for a candle of a given size, and anyone offering you one is describing their candle, not yours. What you can do — and what the next guide in this series does — is judge your own rate against your jar diameter and wick configuration by normalising it against the pool it has to maintain. And once you have two rates from two candles, the reason to keep working in grams per hour rather than hours is set out in grams per hour versus total hours.

What the measurement costs to set up
Three products, two of which you were going to buy anyway. The scale is the only purchase that exists purely for this measurement, and it is also the one that makes your fragrance load repeatable — load is a weight percentage, so a maker without a scale is guessing at the recipe as well as at the burn.

₹354, one variant, and the only tool the weigh-pair actually requires. Its product page states that it "shows measurements in grams or ounces"; it does not state a capacity or a resolution, so run the five-minute check above before you trust it with a specification. For burn-rate work, repeatability beats accuracy — a constant offset vanishes in the subtraction, while scatter does not. Keep it taped to one spot on a hard, level surface and use it for weighing out fragrance as well, because an 8% load on a 150 g candle is 12 g of oil and nobody eyeballs 12 g.

Without a thermometer those are decorative numbers. Note that in the 150 gram jar family and the Apothecary jar, the stated hot-pour ceiling is 85°C — where two limits overlap, the lower one governs.

Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. We would sell more wax by printing a cheerful burn time next to every wick we list. We do not, because we have never burned your candle in your jar in your room — and a supplier's hours figure, once a customer disputes it, is your problem rather than ours. The honest service we can offer is the method and the arithmetic, which is what this page is.
Every price and specification here comes from live CSI stock in September 2026 and links to the product page, where current pricing always takes precedence. The weighing scale page states that it shows measurements in grams or ounces; it does not state a capacity or a resolution, and we have not supplied one. Wax temperatures and the cure instruction are quoted only from the pages that state them. The 9.2 g/h, 352.4 g and 315.6 g figures are a worked example of the arithmetic, not a measured result for any CSI product — no CSI wax, wick or jar page publishes a burn time or a consumption rate.

Frequently asked questions
Do I need to know the empty jar's weight to calculate burn rate?
No. The glass, the wick tab, the sticker and the label are all present in both weighings, so they cancel completely in the subtraction. This is the method's biggest practical advantage: it works on a candle you poured months ago without recording anything. You only need the empty jar's weight for a different calculation — working out how much wax is left behind at end of life, where you weigh the finished jar and subtract the clean empty weight.
How accurate does my scale need to be for burn testing?
Less accurate than you think, but more repeatable. A scale that reads everything 4 g heavy gives a perfect burn rate, because the offset appears in both readings and subtracts away. What hurts is scatter: if the same candle weighs 352 g, 349 g and 354 g on three liftings, your weigh-pair carries about 6 g of noise. CSI's ₹354 scale page states only that it reads in grams or ounces, so check its smallest step and its repeatability yourself before you set a specification.
Should I weigh the candle hot or cold?
Cold, every time. The mass does not change as wax solidifies, so hot weighing is not wrong in principle — it is wrong in practice. A jar of liquid wax drips on the scale, smears on your hands and loses real grams that your arithmetic will blame on the flame, and a jar hot enough to need two hands is a hazard beside a glass surface. Wait until the pool has a solid skin all the way across and the glass is comfortable to hold, then weigh.
How many hours should one burn test session be?
Three to four hours. On a scale reading to the nearest gram, a one-hour session leaves about ±1 g/h of pure measurement noise — roughly 11% of a 9.2 g/h result — while four hours brings that to ±0.25 g/h, under 3%. Beyond four hours the scale stops limiting you and sloppy timekeeping takes over, so the better investment is writing start and stop times to the minute rather than sitting with the candle for eight hours.
Can I calculate burn rate from total burn hours and the fill weight instead?
You can, but it answers a different question and it flatters the candle. Fill ÷ hours assumes every poured gram was consumed, and container candles rarely finish clean. A 150 g candle that ran 18 hours and left 11 g on the glass gives 8.33 g/h by fill and 7.72 g/h by what actually burned. Use the weigh-pair while you are developing, and keep the fill-weight figure only for the back of an envelope.
Does CSI publish grams per hour or burn hours for its waxes and wicks?
No. No CSI wax, wick or jar page states a burn time, a burn rate or hours per gram, and this guide does not estimate one for any product. The same wax behaves differently in a 6 cm jar and a 10 cm jar, with one wick or two, at 8% load or 10% — so a single published figure would be misleading rather than helpful. What the pages do state, where they state it, is fragrance load, add and pour temperatures, cure guidance and jar dimensions, and those are quoted here exactly as published.

Figures verified September 2026: Candle Making Weighing Scale ₹354 (page states it "shows measurements in grams or ounces"; capacity and resolution are not stated and are not asserted here). Pen Thermometer For Candle Making ₹354. Luxury Soy Wax Chunks 500 g ₹299, 1 kg ₹599, 5 kg ₹2,995, 10 kg ₹5,999 — page states up to 13% fragrance load (8–13% of total wax weight, 10% recommended), fragrance add 80–90°C, pour 70–80°C (its details table also states 75–80°C), and cure a minimum of 48 hours, ideally 1–2 weeks, before performing burn tests. Eco Soy CSI 400 1 kg ₹399 — page states fragrance added at 80–90°C (85°C) with 2 minutes of stirring. Eco Candle Wicks Thin (C1) 10 wicks ₹59. The 150 gram jar family and the Apothecary Glass Candle Jar state "safe for hot-pour up to 85°C". Loads and temperatures are wax formulation figures from the product pages, not regulatory limits. Measurement maths: rate = (weight before − weight after) ÷ hours; worked example 352.4 g − 315.6 g = 36.8 g over 240 minutes = 9.2 g/h. Scale-noise column = 1 g ÷ session hours, shown as a percentage of 9.2 g/h; timing column = 5 minutes ÷ (60 × session hours). Fill-versus-consumed comparison uses a 150 g fill, 11 g residue and 18 hours: 150 ÷ 18 = 8.33 g/h against 139 ÷ 18 = 7.72 g/h. Wax cost per 150 g candle at 8% load = 138 g × ₹0.599/g = ₹82.66. No CSI wax, wick or jar page publishes a burn time, a burn rate or hours per gram, and no such figure is stated or implied for any CSI product on this page — every rate shown is either a worked example of the arithmetic or a measurement the reader takes themselves. Prices and availability change — the linked product pages are always authoritative.
