CSI Wick Diagnosis · Batch to Batch
Same recipe, same wick name, taller flame. The formula didn't change, so something in the batch did, and the wick lot is the first suspect. Here is how to prove it in two cheap stages before you touch the recipe.

two packs of centring bars: all stage 2 needs if you kept old-lot wicks · CSI live pricing, October 2026
Quick answers — read this first
Same formula, new batch, taller flame. Should I compare wick lots before changing the formula? Yes. If the recipe didn't change, something in the batch did, and the wick lot is the most likely suspect because the flame lives on the wick. Changing the formula to correct a wick difference would bake the problem into every future batch.What do I check first? Burn a retained candle from the old batch beside a new one, same day, same room, same trim, for 4 hours. If both are tall, the batch is not the cause: your room, trim or measuring changed. If only the new one is tall, the batch is.
How do I prove it is the wick lot? Measure ten wicks from each lot side by side (length, tab neck height, width, braid and coating), then pour 6 candles from one pot of today's mix: three on old-lot wicks, three on new-lot wicks. Only the wick differs, so only the wick can explain the result.
And if I didn't keep any old wicks? Then you can't isolate the lot; run the batch-variable audit instead and requalify the new lot against one CSI rung down (C1 20-pack, ₹118.00). And from now on, keep ten wicks from every lot.
The short answer
The principle: same formula, different flame means a variable changed between batches. Find it before you touch the formula: wick lot first, then oil lot, wax lot, fill, wick height, centring, cure age, room and measuring.
Stage 1 (free): retained old-batch candle beside a new-batch candle, one 4-hour session in still air. Both tall: not the batch. Only new tall: the batch.
Stage 2 (lot isolation): old-lot and new-lot wicks, three candles each, one pot of today's mix, centred, cured together, burned to the end. Only the wick differs.
Stage 3 (if the new lot is stronger): finish production on old-lot wicks if you have them, ask CSI about the two orders, and requalify the new lot against one rung down before it goes into production.

Top: two wicks sold under the same name, one from each order, drawn as a measuring template. The example readings differ only in width and braid; yours may differ in length, tab neck height or coating instead. CSI publishes no wick specifications or lot data, so this comparison is yours to make. Bottom: an illustrative stage 1 and stage 2 result. The retained old-batch candle and the old-lot wicks in today's mix agree; the new-lot wicks in the same mix burn taller from hour one. That isolates the wick lot. Had the retained candle grown too, the room, trim or measuring would be the cause.

Straight answer
My candle flame is taller than the same formula from my previous batch. Should I compare wick lots before changing the formula?
Yes, compare first and change nothing until you have. A formula that worked last batch and misbehaves this batch is telling you a material or process changed, not that the formula was wrong. The wick lot is the first suspect because wicks are woven and coated products whose construction can vary between production runs, and the flame sits directly on them. Prove the batch is different by burning a retained old-batch candle beside a new one in the same session. Prove it is the wick by pouring candles from one pot of today's mix on old-lot and new-lot wicks, three each, centred and cured together. If the new-lot candles burn taller while the old-lot candles match your retained candle, the wick lot is the cause. Only then decide: use your remaining old-lot wicks, requalify the new lot one rung down, or ask your supplier. Rewriting the formula to absorb a lot difference means the next lot breaks it again.
One line: retained candle beside new candle, then old-lot against new-lot wicks in one pot of today's mix; the formula is the last thing you change.
The lot test, priced: if you kept old-lot wicks, stage 2 needs only centring bars, 2 packs for ₹236.00. If the new lot proves stronger, the Eco C1 20-pack (₹118.00) covers a full requalification one rung down, pairs included. All in stock on 7 October 2026.

What can change between two batches of "the same" candle
A recipe is a list of ingredients. A batch is a list of lots, temperatures and days.
Your formula says "200 g, 8% oil, C2, this jar". Your batch also contains a wick lot, an oil lot, a wax lot, a pour temperature, a fill weight, a trimmed wick height, a centring job, a cure age at the time you tested, and the room you tested in. Any of them can move a flame. The worked example in this post: last batch's flame sat around 2.9 cm at hour three; this batch's reaches about 4.0 cm, 1.1 cm taller, same recipe.
Wicks top the list for a physical reason: the flame's size depends on how much fuel the wick draws up, which depends on its construction (braid tightness, fibre, thickness, any coating). Two production runs of the same wick can differ slightly in any of these, and CSI's wick pages state no construction specification and no lot data, in the text we captured. We do not claim our lots are identical, and you should not assume any supplier's are.
The other materials matter too, more weakly. A new oil lot can differ in how it burns (a tendency; CSI publishes no oil batch data, and lot questions go to WhatsApp). A new wax lot can melt slightly differently. These are why stage 2 below pours both wick lots from one pot of today's mix: it removes the oil and wax lots from the comparison at a stroke. For fragrance-strength swings between batches, the stock audit in the batch-to-batch fragrance post covers oil age and storage.
Safety first, plainly: a flame 1.1 cm taller than your approved batch is a reason to hold that batch, not to ship it and see. Don't sell candles from a batch whose flame differs from the approved one until you know why. During tests, stop any session where the flame smokes or reaches towards the glass. Never judge glass by touch: use your own non-contact thermometer at marked points (CSI lists none; our Pen Thermometer is for wax). No wick change makes a candle "safe", and nobody can promise that one will.
The batch variables ranked: your test or your materials?
Half the variables are how you made or tested this batch. Rule those out for free.
Cause ranking · same formula, taller flame than last batch
Process and testing (P) vs materials (M) · ranked by likelihood for this pattern and cost to test (judgement) · signs are common observations, not CSI data
| Variable | What you'd see | Discriminating test | Fix | Cost |
|---|---|---|---|---|
| 1. Wick lot (M) | Taller from hour one on every new candle; new wicks look or feel different (width, braid, sheen) | Stage 2: old-lot vs new-lot wicks in one pot of today's mix | Use old lot; requalify new lot one rung down | ₹236.00 for centring; ₹118.00 if requalifying |
| 2. Wick height above the wax (P) | Tall first flame that settles after the first trim; new batch trimmed longer at finishing | Measure exposed wick on five finished candles from each batch | Trim to a fixed height at finishing (5–6 mm before first light) | Nothing |
| 3. Testing conditions (P) | Retained old candle also burns tall today; fan, AC, season or room changed | Stage 1: retained candle beside new candle, same session | Test in still air in one recorded room | Nothing |
| 4. Cure age at test (P) | New batch tested at day 2, old at day 14 | Re-test the new batch at the old batch's age | Fix a test age (for example day 7) and keep it | Nothing |
| 5. Centring and tab seating (P) | Flame leans, one-sided pool, tab lifted or tilted | Look down the jar; check tab adhesion on a spare | Centring bars or a setting tool; stickers | From ₹100.00 |
| 6. Fill weight (P) | Candles lighter or heavier than 200 g; different headspace | Weigh five candles from each batch (tare the jar) | Fill by weight | Nothing |
| 7. Oil lot or wax lot (M) | Taller flame persists even with old-lot wicks in the new mix | Stage 2 clears the wick; then old vs new oil (or wax) on one wick lot | Ask your supplier about the lot; retest | Your own materials |
| 8. Pour temperature or process (P) | New batch poured hotter or cooled faster; surface or adhesion looks different | Compare batch sheets; repeat at the old figure | Follow the wax page figure (CSI 464: "Pour Temperature 80°C – 90°C") | Nothing |
Variable 2 is the sneaky one. If the old batch was trimmed to 5 mm at finishing and the new one went out at 12 mm, the first burn's flame will be taller on every new candle and look exactly like a stronger wick. It settles after one trim; a stronger wick lot doesn't. Variable 3 is why stage 1 exists: a retained candle is the only fixed reference you have, so if it is tall today too, the batch didn't change; your test did. If you have no retained candle, the same logic applies to a known-good candle of any earlier batch.
The batch sheet that makes this quick next time
For every batch write: wick type and order number (or the date the pack arrived), oil and wax order numbers, pour temperature, fill weight, exposed wick after trimming, cure date, test room, and keep ten wicks from every new lot sealed and labelled plus one or two finished candles (our judgement). Then the next "taller than last batch" takes one evening to diagnose. How long to keep reference samples, and how to use them in disputes, is the reference-sample post.Measuring two wick lots side by side
Look before you burn. Some lot differences are visible on the bench.
Take ten wicks from each lot. Lay them in two rows on white paper under the same light, and photograph them together with a ruler in the frame. CSI lists no ruler or calliper; a steel ruler and your phone's macro mode are enough to see most differences, and a vernier calliper of your own helps with width.
Physical comparison · 10 wicks per lot
What to record · what a difference might mean (tendency, not a prediction) · CSI publishes no wick specifications to compare against
| Measure | How | A difference may mean |
|---|---|---|
| Total length, tab to tip | Ruler, all ten, note range | Mostly a pouring difference (how much stands above the wax); rarely the flame itself once trimmed |
| Tab neck height | Ruler at the crimp | Changes where the flame stops at the end of the jar; matters in the last centimetre |
| Width at the middle | Calliper if you have one; otherwise side-by-side macro photo | A visibly wider wick commonly draws more fuel: a candidate for a taller flame |
| Braid and stiffness | Look and bend gently | Tighter or looser braid, or a different curl, can change burn |
| Coating or sheen | Look under light; scratch a spare | A different priming wax or coating can change how the wick lights and burns |
| Weight of 20 wicks | Weigh together (a 1 g scale can't weigh one) | A clearly heavier lot is a physical difference worth burning |
Visible differences are a reason to burn, not a verdict: two lots can look identical and burn differently, and two that look slightly different can burn the same. Hidden variables (fibre, ply count, core, coating chemistry) are covered in same length and thickness, different burn. If the tab looks different, the effect shows only at the end of the jar; the tab-change post has that end-of-life test.
The three-stage lot test and the equivalence rule
Stage 1 asks whether the batch changed. Stage 2 asks whether the wick did.
1
Stage 1: retained candle beside new candleOne retained candle from the old batch and one from the new, trimmed to 5–6 mm, same room, fans and AC off, lit together, logged at 1, 2, 3 and 4 h (flame height with a ruler behind, pool depth with a skewer). Same flame: the batch didn't change, so check your room, trim and measuring. New one taller: go to stage 2.
2
Stage 2: pour the lot-isolation candlesOne pot of today's mix (200 g at 8% = 16 g oil + 184 g wax each, load on total weight), 6 candles in identical jars: three on retained old-lot wicks (3 needed), three on new-lot wicks. Same sticker, centring bar, pour temperature and trim height for all. Label the bases, not the lids.
3
Cure together, burn togetherAt least 3 days (many oil pages state 48–72 hours for soy; a fixed test age such as day 7 is better). Four-hour sessions in still air, one a day, all six lit at once and spaced apart. Log flame at 1, 2, 3, 4 h; pool depth at 4 h; mushroom and smoke; grams lost per session if you like (that measure is 4842's speciality).
4
Carry it to the endJudge the top, middle and bottom thirds separately. A lot difference that is small at the top can grow lower in the jar where heat builds, and a tab difference only shows in the last centimetre.
5
Apply the equivalence ruleWritten before burn 1 (below). Equivalent: the new lot goes into production. Not equivalent: the new lot is a different wick for your purposes; go to stage 3.
6
Stage 3: requalify a stronger lotTreat it as a new wick: new-lot C2 against C1 single and a C1 pair (in case C1 tunnels), three candles each, 9 candles, full life, with your normal approval rule. From C2 that needs 9 C1 wicks: one 20-pack, 11 spare.
The equivalence rule (in-house, labelled)
Set it before the first burn so the results can't move it. Suggested starting rule: the new lot is equivalent if every new-lot candle stays inside all your written limits (flame band, pool depth, smoke, glass, end of life) in every third, and at each logged hour its flame is within 0.5 cm of the old-lot candles' average. One reading outside either fails the lot. The 0.5 cm band is our judgement, not an industry standard; tighten it if your approved flame already sits near the top of your band. For a release check on every incoming bulk lot, see comparing a new bulk lot against the development sample.Materials for the three stages · 200 g candles at 8%

Argued against our own interest: stages 1 and 2 need no wicks from us at all, and if you already own centring bars, they cost nothing but wax, oil and time. That is the point: a lot comparison should be cheap, so you run it every time instead of guessing.
What to do with the answer, and the CSI buy list
Three outcomes, three different actions. None of them is "rewrite the recipe".
Outcome → action
Our judgement · CSI's wick range is short: C1 → C2 → Cotton Braided, no half-sizes, one wooden width
| Result | Means | Do this |
|---|---|---|
| Stage 1: retained candle is tall too | Your room, trim, cure age or measuring changed | Fix the test conditions; release the batch only after a clean re-test |
| Stage 2: new lot equivalent | The batch difference is elsewhere: wick height, centring, fill, oil or wax lot | Work down the ranking table; one variable at a time |
| Stage 2: new lot not equivalent, stronger | For your candle, the new lot is a different wick | Hold the batch; finish production on old-lot wicks if you have them; requalify (stage 3); ask us about both orders |
| Stage 3: C1 passes | Your formula now needs C1 with this lot | Update the batch sheet; keep 10 wicks of this lot; retest when the lot changes |
| Stage 3: C2 too strong, C1 tunnels | No single CSI rung fits this lot in this jar | Test a C1 pair; or ask us honestly what we stock between C1 and C2 (no sized, tabbed wick) |
Two honest limits. First, CSI publishes no lot data and cannot promise that two packs, or a large order, come from one lot. Send us your order numbers on WhatsApp and we will tell you what we know, but plan on testing every new lot rather than relying on continuity. Second, our range has no half-sizes: if a stronger lot pushes you between C1 and C2, we can't sell you the step in between, and we would rather say so. A different supplier's wick is a different wick, not a different lot; that is 6913's territory.
The production step, with retained wicks built in
Once a lot is approved: production wicks = candles × wicks per candle × (1 + a defect allowance), plus the wicks you retain from that lot. Worked example, labelled: 200 single-wick candles a month with a 2% allowance is 204 C2, plus 10 retained = 214. Buy 2 × 100 + 20 = 220 for ₹2,076.80, leaving 6 spare. The ten retained wicks cost ₹94.40 per lot, which is the cheapest insurance in candle making. Because C2 is ₹9.44 a wick at every pack, buying 500 at once (₹4,720.00) saves nothing per wick; it only ties more of one unknown lot to your shelf until you have tested it.
Don't fix a lot problem with the formula. Dropping the load or swapping the oil to tame a stronger wick lot makes the candle depend on that lot; when the next lot arrives, the formula is wrong again and the scent has changed for nothing. And don't mix lots in one batch: if you must use up old-lot wicks, keep them in their own batch with their own label. One more: don't throw away your last ten old-lot wicks until the new lot has passed. They are your only reference.

What to buy, and what to skip
Four items chosen on page statements, price and stock on 7 October 2026. CSI has no burn data, wick specifications or lot records to rank them on, so each card says what it does for this test and when not to buy it.
1
wick · pre-tabbed · the rung you already use
Eco Candle Wicks — Thick (C2) and Thin (C1)
If your two batches both use Eco C2, the wick lot is the first thing to compare, and you need no new wicks to do it: the test uses the wicks you already hold from each order. In the text we captured, the page states no length, width, braid or lot information, and claims "minimal soot or smoke", which only a correctly sized, correctly trimmed wick can deliver. Argued against our own interest: do not buy a "fresh" C2 pack hoping it will match your old batch; we cannot promise which lot a pack comes from, so ask on WhatsApp what we know about your two orders first. If the new lot proves stronger, the C1 20-pack (₹118.00) is the requalification test. The C1 10-pack is out of stock on 7 October 2026.
| Pack | Price | Per wick | Use |
|---|---|---|---|
| Thin (C1) / 10 | ₹59.00 | ₹5.90 | Out of stock on 7 October 2026 |

accessory · removes the centring variable
Wick Centering Device (Pack of 5)
A wick that set slightly off-centre in one batch burns hotter on one side and can look "taller" when it leans. Wooden bars, "Length 4.4" (11,4 cm)", with one 4 mm hole, for openings the page gives as "less than 4"" (about 10 cm): one wick per bar. Two packs (₹236.00) hold all 6 lot-isolation candles poured together. Limitation: one hole only, so it cannot hold a pair; for double-wick candles you need a multi-slot holder and your own spacing measurement.
| Pack | Price | Per holder | For this test |
|---|---|---|---|
| Pack of 5 | ₹118.00 | ₹23.60 | 2 packs for 6 candles |
₹23.60 a holder, reusable for every lot test. Buy 5 — ₹118.00

tool · holds the wick straight while the wax sets
Wick Setting Tool
A magnetic bar that sits across the jar with a magnetic base underneath. The page describes it as the way to "keep your wick perfectly centered and steady while pouring wax" and says it "Perfectly centers and holds the wick during pouring" (the page's wording). Useful if your batch-to-batch differences come from production, where wicks are glued and set by hand and drift a little in some jars. Argued against our own interest: for a six-candle test, the ₹118.00 centring bars do the same job; buy this only if centring is a production problem.
| Listing | Price | Stock | Best for |

accessory · fixes the tab to the jar base
Candle Wick Stickers (40 stickers)
A tab that lifts or tilts during the pour changes how high the wick stands above the wax, which is one of the batch variables in this post. The page describes "10mm Candle Wick Round Stickers" for fixing the tab before pouring. Use the same sticker in both lots of the test so attachment is not a variable. Limitation: the 100-sticker sheet is out of stock on 7 October 2026; the 40-sticker sheet is ₹100.00, enough for this test several times over.
| Sheet | Price | Per sticker | Stock |
|---|---|---|---|

| 100 stickers | ₹236.00 | ₹2.36 | Out of stock on 7 October 2026 |

Skip for now: a new oil or wax "to bring the flame down" (one variable at a time, and it is probably the wick); Cotton Braided, which is a rung up, not a fix for a stronger lot; and any 500- or 1,000-pack until the new lot has passed stage 2.
The CSI principle
When a proven formula changes behaviour, the formula didn't change. Find the lot that did.
Retained candle beside new candle; old-lot against new-lot wicks in one pot of today's mix; requalify a stronger lot one rung down; keep ten wicks of every lot.

Why trust this guide
CandleMakingSuppliesIndia sells the wicks and accessories named here, not finished candles. This page still tells you that the first two stages need no wicks from us, that we publish no lot data and cannot promise lot continuity, that our wick range has no half-sizes, and that a bigger pack saves nothing per wick.
Every CSI price was checked on the live store on 7 October 2026, with stock checked per pack: the Eco C1 10-pack and the 100-sticker sheet are out of stock and are not offered; every other item priced here is in stock. Page wording is quoted and attributed, including the Eco wick page's "minimal soot or smoke" and the Wick Setting Tool page's centring claims.
The 2.9 cm and 4.0 cm flames, diagram readings, the 0.5 cm equivalence band, the 200-a-month order, the 2% allowance and the ten retained wicks are labelled worked examples or our judgement; the flame band and pool-depth limits are common rules of thumb.

Frequently asked questions
Why is my candle flame bigger than my last batch with the same recipe?
Something in the batch changed: most often the wick lot, the wick height left after trimming, or your test conditions; less often the oil or wax lot, centring or fill weight. Burn a retained old candle beside a new one first, then compare old and new wicks in one pot of today's mix.
Can two packs of the same wick burn differently?
They can: wicks from different production runs can differ in braid, thickness or coating. CSI publishes no lot data and does not claim its lots are identical, so test each new lot against retained wicks from the last one before production.
How do I compare two wick lots?
Measure ten from each (length, tab neck height, width, braid and coating, weight of twenty), then pour six candles from one pot: three per lot, centred, cured together, burned to the end in 4-hour sessions, with an equivalence rule written before burn 1.
Should I keep wick samples from every order?
Yes, in our judgement: ten wicks sealed and labelled with the order number, plus one or two finished candles per batch. At C2 prices, ten wicks cost ₹94.40.
My new wicks burn hotter. Should I reduce fragrance load instead?
No. That ties the formula to one wick lot and changes the scent for nothing. Requalify the new lot one wick size down, or finish production on the old lot, and keep the formula as approved.
Does a taller first flame always mean a stronger wick?
No. If the new batch left more wick above the wax at finishing, the first flame will be taller until the first trim. Measure the exposed wick on finished candles from both batches before blaming the lot.
Same formula, taller flame
Compare the batches, then the wick lots, before you touch the formula.
Stages 1 and 2 need only your retained candles and wicks, plus centring bars (₹236.00 for two packs). If the new lot is stronger, the C1 20-pack (₹118.00) requalifies it one rung down. Send us your order numbers and we will tell you what we know.

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 covers why a proven formula can burn taller in a new batch, a ranked batch-variable table separating process and testing from materials, a physical comparison of two wick lots, a three-stage lot test with an in-house equivalence rule, outcome-to-action guidance, a CSI wick buy list and a production step with retained wicks.Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on the product pages named on each card — Bamboo Stirring Sticks for Mixing Wax, Bamboo Wick Holder, Complete Candle Making Course Kit for Beginners, Eco Candle Wicks, Premium Candle Wicking Needle.

The 200 g test candle at 8% (16 g oil + 184 g wax, total-weight basis) is the series default, labelled. Luxury Soy Wax CSI 464's pour figure is quoted from its page. The 2.9 cm and 4.0 cm example flames, the diagram readings, the 0.5 cm equivalence band, 200 candles a month, the 2% allowance and ten retained wicks per lot are labelled worked examples or judgement. Trim 5–6 mm and the 2.5–5 cm flame band are common rules of thumb. Costs are materials only and exclude labour, freight, packaging and GST. Diwali 8 November 2026 is a calendar fact.
