scale + cutter + the Eco C1 20-pack that confirms an oversized C2 · CSI live pricing, October 2026
Quick answers — read this first
How do I diagnose an oversized flame with six measurements? Log wick length, wick size and fit, pool depth, grams per hour, soot and glass temperature at hours 1 to 4 of a 4-hour session. Score each 0 (within your limit), 1 (borderline) or 2 (over). Then re-run with the wick trimmed to 5–6 mm in still air and see which scores survive.

How do the scores give a verdict? Scores that vanish after the trim point to a trim issue; scores that change with the fan point to a draught. Pool depth and consumption still at 2 after the trim, in still air, is the oversized-wick signature. Soot or a big mushroom with a normal pool and normal consumption points to formulation (oil, load, dye), confirmed with a control candle.

What limits should I use? Your own, written before burn 1. Starting points: pool no deeper than about 1–1.5 cm (rule of thumb), consumption within about 10% of a reference candle, a clean soot card, glass under your own limit. None is an industry standard.

What does the protocol cost? A scale (₹354.00) and a cutter (₹177.00) if you have neither. Confirming an oversized C2 needs the Eco C1 20-pack (₹118.00): ₹649.00 for all three. CSI has no half-sizes between its wicks.
The short answer
The method: six measurements, one recording sheet, two sessions (as found, then trimmed in still air), each measurement scored 0, 1 or 2 against limits you set first.
The verdicts: trim issue (length and soot vanish after a trim); draught (soot and flicker follow the fan); oversized wick (depth and grams per hour stay high after the trim, often with glass at your limit); formulation (soot or mushroom with normal depth and consumption, changing with a control oil or undyed candle).
The confirmation: a verdict is a hypothesis. Confirm "oversized" with three 200 g candles of your current wick, one CSI rung down and a C1 pair, burned to the end, every third judged separately.
Honest limits: CSI lists no non-contact thermometer and publishes no wick, soot or glass data; the wick range has no sizes between C1, C2 and Cotton Braided.

The dashed shape is the retest: trimmed to 5–6 mm, fan off, everything else the same. Wick length and soot fall away, so part of the problem was how the candle was burned. Pool depth and consumption stay at 2 and glass at 1, and that is the part only a wick change can fix. Scores and values are an illustrative worked example, not CSI test data.

Straight answer
How do I diagnose an oversized candle flame using wick length, wick size, melt-pool depth, wax consumption, soot and container temperature?
Measure all six in one session, score them against limits you wrote down first, then change only how the candle is burned and measure again. Session 1, as found: record the exposed wick length before lighting, what wick it is and whether it is centred, then at hours 1, 2, 3 and 4 the flame height, pool depth (skewer), soot (white card), glass temperature (your own non-contact thermometer, marked points) and, at the end, grams lost ÷ hours. Score each 0 (within your limit), 1 (borderline) or 2 (over). Session 2: trim to 5–6 mm, switch off fans and AC, keep everything else the same, and score again. Read the change: if the high scores disappear, it was a trim issue or a draught. If pool depth and grams per hour stay at 2, usually with the glass at your limit, the wick is oversized for that jar and formula. If soot or mushrooming stays high while depth and consumption are normal, look at the oil, load or dye with a control candle. Then confirm before you buy: three candles of your current wick against one CSI rung down, to the end of the jar.
One line: six scores as found, six scores after a trim in still air; what survives is the cause, and a three-candle comparison confirms it.

The six measurements: what each can and cannot tell you

No single reading proves an oversized wick. The pattern does.

Each of the six measurements responds to more than one cause, which is why one alone misleads. A long wick makes the flame tall whatever its size. A draught makes soot whatever the wick. A heavy oil can mushroom a correctly sized wick. Only together, and only when you remove the burning variables in a second session, do they separate the four causes. The table is the reference for the rest of this page.

Six measurements · tool, timing, meaning
Read across: what a high reading suggests, and what it cannot tell you on its own · common observations, not CSI test data
Measurement Tool and timing A high reading suggests On its own it can't tell you
1. Wick length Ruler, before lighting and at hour 4 (before trimming); note any carbon cap A trim issue; or a wick burning slower than the wax falls; or carbon build-up Whether the wick is the wrong size
2. Wick size and fit Record the exact wick, its rung, centring and whether it is upright; compare with any page positioning A wick outside its own page's positioning, or off-centre How it burns in your formula
3. Pool depth Bamboo skewer midway between wick and glass; wet length at hours 1–4 A wick drawing more fuel than the jar needs Whether the jar, a heavy oil or a hot room added to it
4. Consumption Scale: weigh before and after; grams ÷ hours A hot, strong burn Anything without a reference rate to compare it with
5. Soot White card held briefly above the flame at hours 1–4; rim photo after the session Incomplete burning: long wick, draught, oversized wick or heavy formula Which of those it is
6. Glass temperature Your own non-contact thermometer, same marked points, hour 4, each third Heat building in the jar: oversized wick, flame drifting to a wall, the lower third Anything if taken by touch, which you should never do

Two of the six need a reference. Consumption means nothing without a rate to compare with: use an approved candle in a similar jar, or, if you have none, the one-rung-down candle in the confirmation test. CSI publishes no grams-per-hour figures for any wick. Glass temperature needs your own limit; CSI lists no non-contact thermometer and publishes no glass-temperature limit, and the "Safe for hot pour up to 85°C" wording on our 150 g jar pages is a pour limit, not a burn rating. Flame height is deliberately not one of the six: it is the symptom you are diagnosing, and you log it on the sheet as the outcome. If you want the pass line for the flame itself, the impressive-versus-controlled criteria set it.

Safety first, plainly: measuring an oversized flame means letting it burn, so stay with it. Stop the session if the flame smokes continuously, leans towards the glass, or burns close to the base, and record a 2 for that measurement. Never judge glass heat by touch, never insert the skewer close to the flame, and hold the soot card well above the tip for a few seconds only. No result on this sheet makes a candle "safe" or "soot-free".

The recording sheet

If it isn't on the sheet at the time, it didn't happen.

One sheet per candle per session. The header records the conditions that can fake a result; the body records the six measurements and the flame itself. Fill it in at the time, not from memory at the end of the evening.

6. Glass at marked points (your °C) room — — — reading
4. Grams per hour (weight before − weight after) ÷ hours burned, worked out at the end
Small habits that keep the sheet honest
Mark the jar: two dots on the outside at mid-height and two in the lower third, so the glass readings come from the same places every time. One skewer position: midway between wick and glass, pushed straight down until it touches solid wax; the wet length is the depth. A bamboo stirring stick works (₹23.60 each in a pack of five). Weigh with the lid off and after the candle has stopped smoking, so the before and after weights are comparable. Photograph the sheet next to the candle at hour four; it fixes the conditions to the result.

Limits and scores: 0, 1 or 2

A limit you set after the burn will always agree with the candle you hoped would pass.

Scoring makes six different units comparable. Every measurement gets 0 (within your limit), 1 (borderline, worth watching) or 2 (over your limit). The starting limits below are rules of thumb or in-house examples, labelled; change them to suit your range, but change them before the burn, and keep them the same for every candle you compare.

Scoring limits · starting points you replace with your own
In-house protocol, not an industry standard · consumption is relative to your own reference candle · glass limit is yours alone
Measurement Score 0 Score 1 Score 2
1. Wick length at hour 4 Close to the starting trim, no cap Visibly longer, small cap Long, a carbon ball wider than the wick
2. Wick size and fit Approved spec for this jar and formula, centred, upright Not yet qualified for this jar (most first tests) Off-centre or leaning; or a rung whose own page positions it above your jar
3. Pool depth at hour 4 About 1 cm or less About 1–1.5 cm Deeper than about 1.5 cm (rule of thumb)
4. Grams per hour vs reference Within 10% (in the worked example, up to 7.15 g/h) 10–25% over (up to 8.125 g/h) More than 25% over
5. Soot Clean card, clean rim Faint grey card at hour 3–4 Grey card, visible smoke, or a dark rim
6. Glass at hour 4 Well under your limit At your limit Over your limit, or the flame near the wall

The percentages for consumption are an in-house example, not a standard; pick yours from how much variation you see between identical candles. If three candles of the same formula already differ by 10% between themselves, a 10% band will flag noise. The depth bands follow the common rule of thumb that a container pool of roughly 0.5–1 cm is a typical target and much deeper is a warning. There is deliberately no total score: the verdict comes from which measurements stay high, not how many points add up.

From scores to a verdict: the ranked causes

Two causes are how the candle was burned. Two are how it was made. The second session separates them.

Here is the scoring rule. Score session 1 as found. Run session 2 trimmed to 5–6 mm in still air, with nothing else changed. If you suspect a draught, run a third session with the fan back on. Then read the pattern against the table. The ranking is our judgement of how often each cause explains an "oversized" flame, and it is also the cheapest order to rule them out.

Cause ranking · the verdict from the scores
Ranked by how often each explains an oversized-looking flame (judgement) · patterns are common observations, not CSI burn data · ₹ from CSI live pricing, 7 October 2026
Verdict Score pattern you'd see Discriminating test Fix Cost
1. Trim issue (burning: wick length) Session 1: length 2, soot 1–2, flame tall from the start. Session 2: length 0–1, soot 0, depth and g/h 0–1 Session 2 itself: a 5–6 mm trim brings everything back inside limits Trim instructions; and a 10 mm untrimmed start to check the wick has some margin Nothing, or a cutter ₹177.00
2. Oversized wick (making: wick size) Session 2 still: depth 2, g/h 2, glass 1–2; soot often 1; length 0–1 Your wick against one CSI rung down, same formula, three candles each, full life Step down one rung (Cotton Braided → C2 → C1, or to a C1 pair) ₹118.00 (C1 20-pack, from C2)
3. Draught (burning: the room) Soot 1–2 and lean or one-sided pool with the fan on; soot 0 and steady flame with it off; depth and g/h barely change Fan on versus off, same candle, same trim Burn-location advice; check the wick still has margin under a fan Nothing
4. Formulation (making: oil, load, dye) Session 2: soot 1–2 or a big cap (length 2) with depth 0–1 and g/h 0–1; worse in one scent or colour Same wick and jar: your oil against a lighter oil or unscented; dyed against undyed A per-fragrance or per-colour wick, or a lower load within both ceilings Your own oils; a control oil from 50 g

Mixed patterns are common. The worked example below is a trim issue and an oversized wick: the trim removed some of the problem and the depth and consumption that remained are the wick. That is exactly why the second session matters. Formulation is a tendency, not CSI data: vanilla-rich, resinous and dark gourmand oils commonly build more carbon than light oils, and loads move wicks both ways (lavender fine, vanilla huge, bigger flame after lowering the load). If the glass is the high score and nothing else is, check centring and the lower third before anything: a drifting flame heats one wall (pool depth as the candle deepens covers the depth mechanism).

Where this sits in the cluster: individual symptoms each have their own page, from the hour-three growth hub to too large after a correct trim and wax disappearing too fast; this protocol is the common method underneath them. The wider wick-symptom tree across tunnelling and drowning is the systematic diagnosis capstone.

Worked example: one candle, two sessions

A 200 g candle at 8% (16 g oil + 184 g Luxury Soy Wax CSI 464) on an Eco C2 wick, in the reader's own jar, first third. The reader has an earlier approved candle in a similar jar that burns at 6.5 g an hour: that is the reference.

Worked-example log · illustrative values, not CSI data
Session 1 as found (not trimmed since the last burn, ceiling fan on low) · Session 2 trimmed to 5–6 mm, fan off · same candle, top third
Measurement Session 1 reading Score Session 2 reading Score
Flame height h1 → h4 (outcome) 4.2 → 5.8 cm, leaning — 3.4 → 4.9 cm, upright —
1. Wick length 11 mm at start; 14 mm with a cap at h4 2 6 mm at start; 8 mm, small cap at h4 0
2. Wick size and fit C2, centred, not yet qualified 1 same 1
3. Pool depth h1 → h4 0.6 → 2.1 cm 2 0.5 → 2.0 cm 2
4. Grams per hour 9.6 (48% over reference) 2 9.1 (40% over) 2
5. Soot grey card from h3, dark rim patch on the fan side 2 faint card at h4, clean rim 1
6. Glass at h4 at the reader's limit 1 at the reader's limit 1

Reading it. The trim and the still air took wick length from 2 to 0 and soot from 2 to 1, and they straightened the flame. That part was how the candle was burned. What stayed: a pool still reaching about 2 cm, consumption still 40% over the reference (36.4 g in four hours against about 26.0 g), the glass still at the reader's limit, and a flame still climbing towards 5 cm. That is the oversized-wick signature, and it is in the top third, where the candle is coolest. At 9.1 g an hour the 180 g above a 1 cm floor would also run out in about 19.8 hours against 27.7 for the reference rate. Verdict: trim issue plus oversized wick; confirm one rung down. The fan side's dark patch in session 1 is a note for the care label, not the cause.

Don't stop at session 1. Judged as found, this candle looks like "everything is wrong", and the temptation is to change wick, oil and load at once. Session 2 cost one evening and showed which half was the wick. Don't let session 2 flatter you either. A wick that passes only when trimmed exactly and burned in still air has no margin for real homes; the untrimmed-tolerance post shows how to test that margin.

Confirming the verdict: test plan and approval rule

A score sheet makes a good hypothesis. Three candles to the bottom of the jar make a decision.

For the oversized-wick verdict, the confirmation uses the series' default test candle, labelled: 200 g at 8% = 16 g fragrance + 184 g wax (load as a percentage of total weight), in your jar. Three arms: your current wick, one CSI rung down, and a C1 pair in case the single smaller wick tunnels. Three candles each, 9 in all, scored on the same sheet every session.

1
Freeze the limits and the referenceCopy your scoring limits onto every sheet. The reference grams per hour is your approved candle's rate, or, until you have one, the arm that passes.
2
Make nine identical candles except for the wickSame wax, oil lot, load, fill and pour temperature (Luxury Soy Wax CSI 464 states "Pour Temperature 80°C – 90°C" and "Fragrance Load Up to 10%"), poured the same day, wicks centred. Cure them together; many makers burn-test soy from about day 3 and again at day 7 and 14.
3
Burn session-2 conditions onlyTrim to 5–6 mm, fans and AC off, candles spaced apart, room temperature written down, 4-hour sessions. You have already learned what the room does; now you are judging wicks.
4
Score all six every sessionWeigh before and after, skewer at hours 1–4, soot card, glass at the marked points with your own non-contact thermometer. Stop any session where a flame smokes continuously or nears the glass and score it 2.
5
Burn to about 1 cm from the bottomScore the top, middle and bottom thirds separately; the lower third is where an oversized wick is most likely to score 2 on glass and depth (why a two-hour pass fails near the bottom).
6
Apply the approval ruleChoose the arm whose three candles never score 2 and score 0 on depth, consumption and soot in every third. If two arms pass, prefer the one whose pool still reaches the glass from burn two.
The approval rule (ours, labelled)
A wick is approved for a jar and formula when all three candles score no 2 anywhere and 0 on pool depth, grams per hour and soot in the top, middle and bottom thirds, at 4-hour sessions in still air after a 5–6 mm trim. A 1 on glass or wick length is allowed only if it does not rise in the lower third; the fit score of 1 ("not yet qualified") becomes 0 when the arm passes. One 2 in any candle fails that arm. This is an in-house protocol, not an industry standard.

Buying for the protocol, and the step to production

The protocol needs two tools. The verdict decides whether you need any wicks at all.

Argued against our own interest: if your verdict is a trim issue or a draught, the right purchase is a ₹177.00 cutter or nothing, and a clear line on your care label. Only the oversized-wick and formulation verdicts lead to wicks. And measuring tools you already own (a 1 g kitchen scale, your own non-contact thermometer, a bamboo skewer) are as good as ours for this.

CSI's sized, tabbed wicks are three rungs: C1 → C2 → Cotton Braided, so the confirmation step is always Cotton Braided → C2, C2 → C1, or a C2 pair → a C1 pair. There is no sized, tabbed wick between C1 and C2 or between C2 and Cotton Braided, no smaller sized, tabbed wick than C1, and one wooden-wick listing with no widths. If your scores say C2 is oversized but C1 tunnels in your jar, that gap is real: test the C1 pair, adjust on the fragrance side, or ask us on WhatsApp.

The step to production quantity

Once an arm passes, production wicks = candles × wicks per candle × (1 + a defect allowance). Worked example, labelled: 250 single-wick candles a month with a 2% allowance is 255 C1 wicks; buy 2 × 100 + 50 + 20 = 270 for ₹1,593.00 (15 left). A 500-pack (₹2,950.00) costs the same ₹5.90 a wick and ties up ₹1,357.00 more cash. If the confirmation shows C2 was right after all, 260 C2 wicks are ₹2,454.40. Reorder point = daily use × your lead time + safety stock; CSI publishes no lead times, so ask on WhatsApp. Keep using the sheet in production: one candle per batch, one session, six scores, is a cheap early warning when a wick or oil lot changes (what to retest when the wick supplier changes).

Don't buy on a single score. A 2 on soot alone is not an oversized wick; a 2 on depth alone in a hot room is not either. The 1,000-packs (₹5,900.00 C1, ₹9,440.00 C2, ₹12,000.00 Cotton Braided) carry no per-wick saving, so there is never a price reason to buy them before three candles pass to the bottom of the jar.
Diwali is 8 November 2026, 32 days from 7 October 2026. The two diagnosis sessions take two evenings; the confirmation (a 3-day cure, then about seven daily 4-hour sessions) about 10 days. If a festive batch depends on the verdict, run the sessions this week and send us your production wick count on WhatsApp for stock, dispatch and a GST invoice.

What to buy, and what to skip

Five items for the protocol and the confirmation, chosen on page statements, price and stock on 7 October 2026. CSI publishes no burn, soot or glass data, so none is ranked on performance, and each card says when not to buy.

1
tool · measurement 4 · consumption
Candle Making Weighing Scale
Grams per hour is the measurement that turns "it seems to burn fast" into a number you can compare. Weigh the candle before and after each session; grams lost ÷ hours burned is your rate. The page says the scale shows "grams or ounces"; in the text we captured it states no capacity or resolution, so check it reads in single grams and holds your filled jar before you rely on it. Argued against our own interest: if you already own a kitchen scale that reads to 1 g and takes the weight of your jar, use it. The protocol needs a scale, not this one.

Candle Wick Cutter | Candle Wick Trimmer
Measurement 1 compares the wick with a known starting length, so the cut has to be repeatable: about 5–6 mm every time. CSI lists two Candle Wick Cutters (3 cm and 5.5 cm blades) and a Candle Wick Trimmer whose page says "Trim your wick to 1/4 inch before every burn" and "Perfect Length: Ensures optimal flame height" (the page's claim; a trim sets the start, it does not resize a wick). Limitation: no trimmer measures. Check the cut with a ruler the first few times.

wick · pre-tabbed · the confirmation rungs
Eco Candle Wicks — Thin (C1) and Thick (C2)
When the scores say "oversized wick", these are the rungs you confirm it with. In the text we captured, the page states no length, width or jar-diameter range, so the wick-size score for any C1 or C2 starts at 1 ("not yet qualified for this jar") until your own test approves it. The page claims "minimal soot or smoke"; attribute that, and let your soot card decide. C1 is ₹5.90 and C2 ₹9.44 a wick at every pack. Argued against our own interest: the C1 20-pack (₹118.00) covers three single-C1 and three C1-pair candles; no bigger pack is cheaper per wick. The C1 10-pack is out of stock on 7 October 2026.

Cotton Braided Wicks Ready Made
Its page gives the one wick-to-jar statement in CSI's tabbed range: "engineered for large-diameter candles exceeding 8 cm", with "Height of the wick is 10.16 cm" and the claim "optimal flame height, preventing tunneling". If your jar is 8 cm or narrower and this is the wick, score measurement 2 at 2: the page's own positioning sits above your jar, and C2 is the first comparison. ₹12.00 a wick at every pack. Limitation: there is no tabbed size between it and C2.

Pen Thermometer For Candle Making
Measurement 6 needs a non-contact thermometer, and CSI does not list one: this page describes a thermometer to "monitor the temperature of your candle wax", and in the text we captured it states no range. Use it to keep the confirmation candles identical (Luxury Soy Wax CSI 464 states "Pour Temperature 80°C – 90°C"), never on glass. Argued against our own interest: if you already pour with a thermometer you trust, you don't need this one, and for glass you must use your own non-contact thermometer.

Skip for now: any 500- or 1,000-pack before approval; a new oil or wax while the verdict is still open (one variable at a time); the 5.5 cm cutter and the trimmer if the ₹177.00 cutter reaches your wick; and our Pen Thermometer for glass, which it is not for.

The CSI principle
Measure six things, change one, measure again. What survives is the cause.
As found, then trimmed in still air; then three candles per arm to the bottom of the jar. From C2 the confirmation wicks cost ₹118.00.
"A wick is only oversized once you've taken the trim and the fan out of the picture."

Why trust this guide

CandleMakingSuppliesIndia sells the wicks, wax and tools named here, not finished candles. This page still tells you that two of the four verdicts need no new wicks, that tools you already own will do, that our bigger wick packs cost no less per wick, and that our range has no half-sizes and one wooden width.

Every CSI price was checked on the live store on 7 October 2026, with stock checked per pack: the Eco C1 10-pack is out of stock and is not used, and every other item priced here is in stock on that date. Page wording is quoted and attributed, including the scale page's "grams or ounces" (no capacity or resolution stated) and the Eco wick page's "minimal soot or smoke".

The pool-depth bands, trim length and 1 cm wax floor are common rules of thumb. The scoring bands, the 10% and 25% consumption bands, the approval rule and every value in the worked example are labelled examples or our judgement. Fragrance effects are tendencies, not CSI test data. For bulk pricing, GST invoicing, and MSDS and IFRA documentation on request, message us on WhatsApp at +91 7397976926.

Frequently asked questions

How do I know if my candle wick is too big?
Trim it to 5–6 mm and burn it four hours in still air. If the pool still goes deeper than about 1.5 cm, the candle still loses wax much faster than a reference candle, and the glass reaches your own limit, the wick is likely oversized. Confirm with three candles one size smaller.
How do I measure melt pool depth in a candle?
Push a bamboo skewer straight down midway between the wick and the glass until it meets solid wax, lift it out and measure the wet length. Do it at the same spot each hour.
How do I calculate how fast my candle burns?
Weigh it before lighting and after extinguishing; grams lost divided by hours burned is grams per hour. Compare it with an approved candle in a similar jar, because CSI publishes no grams-per-hour figures for any wick.
How do I check if my candle jar is getting too hot?
Use your own non-contact thermometer at the same marked points each session, against a limit you set; never touch the glass. CSI lists no non-contact thermometer, and our jar pages' "hot pour up to 85°C" is a pour limit, not a burn rating.
Why does my candle soot even though the wick seems the right size?
Often a long wick, a draught or the fragrance. Trim to 5–6 mm and burn in still air; if soot persists with a normal pool depth and burn rate, test your oil against a lighter oil on the same wick.
What wick is smaller than C2 at CSI?
Eco Candle Wicks Thin (C1): the 20-pack is ₹118.00 (₹5.90 a wick); the 10-pack is out of stock on 7 October 2026. There is no sized, tabbed wick between C1 and C2; ask us on WhatsApp if you need a finer step.
Diagnosing an oversized flame
Six measurements as found, six after a trim in still air, then three candles per arm to the end.
The protocol needs a scale (₹354.00) and a cutter (₹177.00); confirming an oversized C2 adds the C1 20-pack (₹118.00). If your scores land between our rungs, tell us on WhatsApp and we will say plainly what we stock, and what we don't.

Editorial standards & sources
About this guide: part of CSI's cluster "Flame Is Too Large" (6901–6920) in the series on large flames, soot, smoke, mushrooming and wick purchase. It sets out a six-measurement diagnosis for an oversized flame (wick length, wick size and fit, pool depth, consumption, soot, glass temperature) with a recording sheet, scoring limits, a two-session scoring rule and verdicts, a ranked cause table, a worked-example log, a confirmation test with an in-house approval rule, a CSI wick buy list and a production step.

Non-price figures: the 200 g test candle at 8% (16 g oil + 184 g wax, load as a percentage of total weight) is the series default, labelled. Wax ceiling as the page states (Luxury Soy Wax CSI 464 up to 10%), a formulation limit, not a regulatory one. Trim length 5–6 mm (one trimmer page says 1/4 inch); pool depth about 0.5–1 cm typical and about 1.5 cm as a warning, the 1 cm wax floor (180 g burnable in the worked example) and about one hour per 2.5 cm of diameter (7 cm ≈ 2.8 h) are common rules of thumb. The 0/1/2 bands, the 10% and 25% consumption bands, the reference rate of 6.5 g/h and every log value are labelled worked examples or judgement; diagram scores are illustrative. Costs are materials only and exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
