On a development candle, yes — every cycle, both ends, until the jar stops burning. On production units, no, and this guide draws the line between the two. The reason to log all of it is that the first cycle is the one you would have believed.

how far cycle one sat above the full-life average in the worked log below — 11.33 g/h against 9.79 g/h across five cycles · jars from ₹94.40 each, CSI live pricing, September 2026
Quick answers — read this first
Do I really need to weigh every cycle? On the candle you are developing, yes. A single weigh-pair gives you one cycle's rate, and cycles are not identical. In the five-cycle log below, cycle one measured 11.33 g/h and the full life averaged 9.79 g/h. Anyone who stopped after cycle one would have specified a candle 16% faster than the one they actually make.
How many rows is a full life? Fewer than you fear. A 150 g candle burned in three-hour sittings produced five rows and ten weighings — about 14.2 hours of burning spread over a fortnight, and roughly a minute of bench work per row.
How do I know a row is wrong? It has to add up. Grams consumed across every cycle, plus the wax left in the jar at the end, must equal what you poured. In the log below, 139 g consumed + 11 g residue = the 150 g fill. Ten weighings on a scale reading to the nearest gram give you a closure window of about ±5 g; miss by more and a row is wrong, not the candle.
And in production? You stop. Production units get weighed at fill, and one retained unit per batch gets the full logged life if you ever need to answer a complaint. Weighing every cycle of every candle you sell is not a process — it is a hobby.
The short answer
Every cycle on the development candle: both ends, same scale, same spot, until the candle will not relight. That is the only candle whose rate you are allowed to quote back to yourself.
Three units, not one: run the log on three identical candles from the same pour. The spread between them is your process variation, and it is usually wider than anything your scale contributes.
Reconcile, don't trust: consumed + residue = fill, within the window your scale's resolution allows. A log that does not close has a bad row in it.
Five rows, ten weighings, one defensible number. The bar lengths are grams consumed per cycle; the rate beside each one is what that single row would have told you if you had stopped there.
Should I weigh my candle before and after every burn cycle to calculate its actual consumption rate?
Yes — on the candle you are developing, and no on the candles you sell. The distinction matters because the two activities answer different questions. A development candle exists to produce one trustworthy number, and that number cannot come from a single cycle: in the worked log above, a 150 g candle gave 11.33 g/h on cycle one, 10.00 on cycle two, 9.33 on cycle three, 9.00 on cycle four and 9.09 on the short final cycle, averaging 9.79 g/h across 139 g and 14.2 hours. Cycle one was 16% above the figure the whole candle produced. Had the maker weighed once and moved on, every hours calculation, every cost-per-hour comparison and every label claim downstream would have inherited that error. So the development rule is: weigh at both ends of every sitting, on three identical units, until the candle will not relight — and then check your arithmetic by reconciling it, because 139 g consumed plus 11 g still stuck to the glass equals the 150 g you poured. A log that closes within your scale's resolution is a log you can defend; one that does not has a bad row. In production the discipline changes shape rather than disappearing: every unit is weighed at fill, one unit per batch is retained, and that retained unit gets the full treatment only if a customer ever disputes the hours. Pour into something with a stated fill — the Clear Glass Jar with Golden Lid states ~150 gm capacity and a hot-pour limit of 85°C — and keep one wax and one wick fixed across all three. The weighing technique itself is in how to measure grams of wax consumed per hour.
One line: every cycle on the development candle until it dies, three units in parallel, and a log that reconciles consumed plus residue back to the fill weight — then stop weighing and start producing.
A logged full life needs three identical candles: Clear Glass Jar with Golden Lid 150 gram, pack of 10 at ₹944, Luxury Soy Wax CSI 464 500 g at ₹260, and Eco Candle Wicks Thin (C1), 10 for ₹59. That is a complete test batch with units left over for retained samples.
One cycle measures an evening. A candle is not an evening.
A weigh-pair is an honest measurement of what happened between two readings. The problem is what people do with it: they call it "the candle's burn rate" and divide the fill weight by it to get hours. That move assumes the candle burns at one speed from the top of the jar to the bottom, and it does not have to.
Several things genuinely change as a container candle goes down. The flame sits progressively deeper inside the glass, so the air reaching it changes. The glass itself is warmed from a different height. The pool sits on a thinner and thinner bed of solid wax. The wick has been trimmed four or five times by then, and whatever carbon it carries has accumulated. None of this is mysterious, and none of it is a defect — it is simply why the honest unit of measurement is the cycle, and why a candle's rate is the aggregate of all its cycles rather than any one of them.
What direction the drift takes is not something anyone can tell you in advance, and this guide is not going to pretend otherwise. In the worked log the rate fell as the jar emptied. In another maker's jar — different diameter, different wax, different wick — it could climb, because a warmer glass and a deeper flame recess can push the other way. The usable conclusion is not "cycle one is always fast". It is "you cannot know which way yours drifts without the rows", and the rows cost you one minute each.

Worked out above: each cycle's rate = consumed ÷ session hours. Running average = cumulative grams ÷ cumulative hours: 34÷3.0 = 11.33 · 64÷6.0 = 10.67 · 92÷9.0 = 10.22 · 119÷12.0 = 9.92 · 139÷14.2 = 9.79. Cycle one against the life: 11.33 ÷ 9.79 = 1.158, so 16% fast. Two cycles against the life: 10.67 ÷ 9.79 = 1.090, still 9% fast. The jar and candle weigh 352 g together at the start and 213 g when it stops, leaving 11 g of wax against a 150 g fill. These are one maker's readings illustrating the method — not a figure published for any CSI wax, wick or jar, because no CSI page publishes one.
The mistake: calling cycle one "the burn test". It is the most natural thing in the world — you poured, you cured, you finally got to light it, you wrote down a number and it felt like an answer. But cycle one is the only cycle burned on a completely full jar with a cold glass and a factory-fresh wick, which makes it the least representative hour the candle will ever burn. It is also the cycle makers are most tempted to judge wicking on, which is how a candle gets over-wicked in pursuit of a fast first melt pool: see chasing an edge-to-edge melt pool on the first burn.
The log row: what earns a column and what doesn't
Burn logs fail in two ways. Most are too thin to diagnose anything — just hours and a tick — and a few are so elaborate that the maker abandons them by cycle three. The row below is the smallest set of fields that lets you answer, six months later, both "what was the rate?" and "why was that row different?"

What does not earn a column: anything you will not fill in reliably. Perceived throw on a ten-point scale, guessed pool depth in millimetres, humidity you did not measure. Those belong in a separate development sheet where guesses are allowed, not in the row that produces your rate. Hot-throw scoring has its own method in how to test hot throw before launching a candle fragrance.
Write the row on the jar, then copy it
Stick a plain label on the base of each test candle and write the weigh-out number straight onto it in pen. Transfer the row to your sheet afterwards. The reason is brutally practical: the moment you lose which jar is unit A and which is unit B, three logs become one worthless average. A ₹354 scale and a pen do the whole job, and the label comes off before the candle becomes a retained sample.
The sum that catches a bad row
This is the part that turns a log into evidence. Every gram you poured has exactly two possible destinations: it went up the flame, or it is still in the jar. So the arithmetic has to close.
Sum of all cycles' consumed grams + wax remaining in the jar at end of life = fill weight. In the worked log, 34 + 30 + 28 + 27 + 20 = 139 g consumed, and the finished jar held 11 g of unburnable wax against the glass and under the tab. 139 + 11 = 150 g, the fill. The log closes, so the rows are internally consistent.

At this point the closure test is too loose to be useful — log longer cycles, not more of them
Worked out above: each weighing carries up to ±0.5 g on a scale whose smallest step is 1 g, so n weighings carry up to ±0.5n g in the worst case. Percentages are against a 150 g fill. If your scale resolves to 0.1 g, divide every window by ten. The arithmetic is generic; it assumes nothing about any CSI product.
Notice the bottom row. Logging twelve short cycles instead of five long ones does not give you a better number — it gives you twice the weighings and a closure test so wide that a genuine error hides inside it. This is the same conclusion the session-length arithmetic reaches from the other direction: fewer, longer sittings beat many short ones, for the rate and for the reconciliation alike.
Each row's before-weight should equal the previous row's after-weight. If it does not, something happened between sittings: the candle was moved to a different scale, a lid went on, wax was chipped off, or someone lit it for five minutes and did not tell you. Write both numbers anyway and flag the gap rather than quietly overwriting one. A log with an annotated discrepancy is worth far more six months later than a tidy log you no longer believe. Batch-level investigations start here too — see which production records to investigate.
The running average, and the honest moment to stop
The running-average column in the log table is the most useful thing on this page, because it tells you when further cycles stop changing your answer. In the worked log it moved 11.33 → 10.67 → 10.22 → 9.92 → 9.79. The first three cycles shifted it by over a gram per hour. The fourth moved it 0.30. The fifth moved it 0.13 — and the fifth was the candle dying, so there was nothing left to measure anyway.
That shape is the point. Early cycles move the average a lot; late cycles barely move it. Which means the question "can I stop at three cycles?" has an answer you can compute rather than guess: stop when one more cycle would change the running average by less than you would act on. If you would not change a wick over 0.2 g/h, there is no need to keep logging once cycles are moving the average by less than that — but you must still burn the candle to extinction, because you need the residue figure to reconcile and to calculate usable hours. Weighing can relax; burning cannot.
1
Pour three identical units and weigh each at fillSame wax, same load, same wick, same jar, same pour temperature, poured within minutes of each other. Weigh each filled jar cold and write it on the label — this is the number the whole reconciliation depends on, so it is the one weighing you cannot skip. Three units let you separate candle-to-candle variation from cycle-to-cycle drift.
2
Cure before cycle oneSoy container candles are conventionally cured 14 to 21 days, and the Luxury Soy Wax Chunks page asks for a minimum of 48 hours and ideally one to two weeks before burn testing. A log that starts too early is measuring the cure, and the cure is not what you are about to change. Keep all three units together, lids on, out of the light.
3
Run all three units in the same sittingThree candles side by side, same room, same evening, same three-hour window, each with its own weigh-in and weigh-out. This is why the method is cheap: one evening produces three rows, not one. Keep them far enough apart that they are not heating each other.
4
Compute the running average after each sittingCumulative grams ÷ cumulative hours, per unit. Write it in the row. Watch how much it moves. When it stops moving by an amount you would act on, you have your rate and you can stop writing rates — but keep burning.
5
Burn to extinction and weigh the residue properlyWhen the candle will not relight, weigh the whole jar one last time, then — on one unit only — scrape it clean, weigh the empty jar, and work out the wax left behind by subtraction. Now you have both a defensible rate and the usable-wax figure that turns it into hours. The correction itself is in fill weight versus actually consumed wax.
6
Reconcile all three logs before you believe any of themConsumed + residue = fill, for each unit, inside the closure window for the number of weighings you took. Then compare the three units' rates to each other. The spread between them is the honest uncertainty on your candle — not the scale's resolution, and not the neatness of your spreadsheet.
The CSI principle
Weigh every cycle of the candle nobody will ever buy, so you never have to weigh the ones they do.
The development candle is the only unit in your whole operation whose job is to be measured to death. Give it the full ten weighings and it buys you permission to stop measuring everything after it — which is the real reason the discipline is worth it. A maker who skips it ends up weighing production candles after a complaint, which is the most expensive time to start.
Development, qualification, production: three different weighing regimes
"Should I weigh every cycle?" is really three questions with three answers, depending on which stage the candle is at. Here is where the effort belongs.

Whether the batch changed or the customer's use did
The row that saves the most money is the third one. Weighing every production unit at fill takes a second per candle and eliminates the single largest source of hours variation between units, which is simply how much wax went in. Two candles with the same rate and a 10 g difference in fill differ by about an hour of life at 10 g/h — and an inconsistent pour, unlike a wick, costs nothing to fix. Whether a rate range belongs in your written specification at all is taken up in should my specification include a grams-per-hour range.

A burn log feels like homework while you are writing it and like insurance the first time someone questions your candle. Four things it does that nothing else can.
It dates your formulation. When a wax supplier changes, or an oil is reformulated, or you switch wick packs, the log is the before-picture. Without it, "the candles seem faster now" is an argument; with it, it is a measurement. This series treats a new oil or a new wax as a formulation change requiring full-life retesting — see should changing soy wax suppliers trigger full-life burn testing.
It separates use variation from a batch problem. A customer reporting a short candle has told you about one unit burned in a way you cannot see. Your log tells you what the candle does in ordinary three-hour sittings with trimming, which is the only basis on which to judge whether their experience is unusual.
It gives your label an audit trail. Any hours figure you print should trace back to rows you can produce: this many units, these cycles, this residue, this session length and this trimming assumption. On labelling obligations as such, take advice from a qualified adviser rather than from a supplier's blog.
It makes the next product cheaper to develop. Once you have a logged rate for one jar and one wick, a second SKU in a different vessel starts from a measured per-wick figure rather than from scratch — which is the groundwork for the testing matrix in building a wax, fragrance and wick testing matrix.
What to pour so you have something worth logging
Three identical units, one variable at a time, and a vessel whose page states its fill capacity so you know what you poured before you weigh it. Each card shows every listed pack and the per-unit price, because a logged programme is bought by the unit rather than by the kilo.
1
Test vessel · stated fill, stated hot-pour limit
Clear Glass Jar with Golden Lid (150 gram)
The jar to standardise a log on, because its page gives you the two numbers a test needs: a stated fill capacity of ~150 gm and a stated limit of "safe for hot-pour up to 85°C". That 85°C matters when your wax page says something higher — CSI 464's page states melt and pour at 80–90°C, so in this jar 85°C is the ceiling that governs. Dimensions are stated as roughly 8 cm tall with the lid, a 7 cm outer rim and a 6.5 cm base, which is the information you will need when you normalise your rate against pool area. Sold in packs of 10 and 20 at the same per-jar price, so three test units and a retained sample come out of one pack of 10 with six to spare. One CSI customer, Soumili Gope, simply notes that "the jars were of good quality".
A flake container wax at ₹507.40 a kilo whose page states a fragrance load of up to 10% and gives melt and pour as 80–90°C. Flakes are easy to weigh out in the small, exact quantities a three-unit test needs, and the stated ceiling means your 8% test sits inside a published window rather than at the edge of one. Three 150 g candles at 8% need 414 g of wax, so the 500 g pack at ₹260 covers a full test — though note the 500 g pack works out at ₹520 a kilo against ₹507.40 at 1 kg, so if a second round is likely, buy the kilo. Thenirvaofficial calls it "one of the best wax for container Candles. Easy to work with, especially if you are a beginner."

One wick, held constant across the log
Eco Candle Wicks · Thin (C1)
The wick to hold fixed while you learn to log, at ₹5.90 each at every pack size from 10 to 1,000 — flat pricing, so a development pack costs you nothing extra per wick. Be clear about what the page does and does not say: it states that the wicks "pair perfectly with soy wax, beeswax, and other eco-friendly waxes", and it states no diameter and no jar size. The C1 and C2 designations appear only as variant names. That is precisely why the log exists — with no published sizing to lean on, your own rows are the only evidence about which of the two belongs in a 7 cm jar. Ashwini's review reads simply "Quality wick, works very well".

Why trust this guide
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. A supplier's natural instinct is to tell you a wick is right for a jar and let you pour a thousand of them. We are telling you to pour three, weigh them ten times each and keep the paperwork — because the only reason anyone needs this discipline is that nobody, including us, has ever burned your candle.
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 Clear Glass Jar with Golden Lid page states a fill capacity of ~150 gm, dimensions of approximately 8 cm height with lid, 7 cm outer rim and 6.5 cm base, and "safe for hot-pour up to 85°C". CSI 464's page states up to 10% fragrance load and melt and pour at 80–90°C; where that conflicts with a jar's 85°C limit, the lower figure governs. The Eco Candle Wicks page states no diameter or jar size — we have not supplied one. The five-cycle log, the 9.79 g/h average and the 16% figure are a worked example of the method, not measured results for any CSI product: no CSI wax, wick or jar page publishes a burn time or a consumption rate.

Frequently asked questions
How many burn cycles do I need to log before the rate settles?
Watch the running average rather than counting cycles. In the worked log it moved from 11.33 to 10.67 to 10.22 to 9.92 and finally 9.79 g/h — the first three cycles shifted it by more than a gram per hour, the fourth by 0.30 and the fifth by 0.13. Stop computing new rates when one more cycle would move the average by less than you would act on. But keep burning to extinction regardless, because the leftover-wax figure is what converts a rate into honest hours.
Can I just weigh at the start and the end of the candle's life?
You can, and you will get a correct full-life average — but you lose every diagnosis. Two weighings cannot tell you that the candle ran fast at the top and settled lower down, which is exactly the information that decides whether a wick is right. They also cannot catch their own errors: with no intermediate rows, a mistake in either weighing is invisible. Two weighings are fine for a retained sample; for development, the per-cycle rows are the product.
Does the candle need to cool completely between burn cycles?
Yes, to a solid pool and a glass that is comfortable to hold. Mass does not change as wax sets, so a warm weighing is not wrong in theory — but liquid wax drips, smears and transfers onto your hands, and every one of those grams gets blamed on the flame. A fully set surface also means the next cycle starts from the same physical condition as the last, which is the whole point of a controlled log.
Should I weigh every production candle as well?
Weigh every production candle at fill — it takes a second and it removes the biggest avoidable source of hours variation between units. Do not burn-log production candles. Instead, keep one retained sample per batch, weighed at fill and stored unburned, so that if a customer ever disputes the hours you have a unit from that exact batch to test against your master candle's log. That is a records question, covered in retaining a sample from each production batch.
My log does not add up — consumed plus leftover is 7 g short of the fill. What now?
With five cycles and ten weighings on a 1 g scale, the legitimate closure window is about ±5 g, so 7 g says a row is wrong rather than the candle. Check in this order: the residue weighing (easy to mis-scrape), then whether each row's before-weight matches the previous after-weight, then whether a lid was on for one weighing, then whether a wick was trimmed after a weigh-in. Annotate what you find instead of adjusting a number to make the sum close.
Does CSI publish a consumption rate I can check my log against?
No. No CSI wax, wick or jar page states a burn time, a burn rate or hours per gram, and nothing on this page estimates one. What the pages do publish is quoted exactly: the 150 gram jar's ~150 gm fill capacity and 85°C hot-pour limit, CSI 464's up to 10% load and 80–90°C melt and pour, and the fact that the Eco Candle Wicks page states no diameter at all. Your log is the only source of a rate for your candle — which is why it is worth keeping.
Three candles, ten weighings, one number
Log the candle nobody buys, and you will never have to weigh the ones they do.

Figures verified September 2026: Clear Glass Jar with Golden Lid (150 gram) pack of 10 ₹944, pack of 20 ₹1,888 — ₹94.40 per jar; page states fill capacity ~150 gm, height approx 8 cm with lid, outer rim approx 7 cm, base approx 6.5 cm, "safe for hot-pour up to 85°C". Luxury Soy Wax CSI 464 500 g ₹260, 1 kg ₹507.40, 5 kg ₹2,537, 10 kg ₹5,074 — page states up to 10% fragrance load and melt and pour 80–90°C. Eco Candle Wicks Thin (C1) 10 ₹59, 20 ₹118, 50 ₹295, 100 ₹590, 500 ₹2,950, 1000 ₹5,900 — flat ₹5.90 per wick; page states compatibility with soy, beeswax and other eco-friendly waxes and states no diameter or jar size. Candle Making Weighing Scale ₹354. Luxury Soy Wax Chunks page states cure a minimum of 48 hours, ideally 1–2 weeks, before performing burn tests. Loads and temperatures are product-page formulation figures, not regulatory limits. Log arithmetic: cycles of 34 g/3.0 h, 30 g/3.0 h, 28 g/3.0 h, 27 g/3.0 h and 20 g/2.2 h give 139 g over 14.2 h = 9.79 g/h; running averages 11.33, 10.67, 10.22, 9.92, 9.79 g/h; cycle one against the life 11.33 ÷ 9.79 = 1.158 (16%); two cycles 10.67 ÷ 9.79 = 1.090 (9%); reconciliation 139 g consumed + 11 g residue = 150 g fill. Closure windows assume ±0.5 g per weighing on a scale resolving to 1 g. Wax cost per 150 g candle at 8% load = 138 g × ₹0.5074/g = ₹70.02; a three-unit test consumes 414 g of wax and 36 g of oil. 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. Prices and availability change — the linked product pages are always authoritative.
