My Candle Flame Is Tiny and Wax Consumption Is Extremely Slow — Should I Test a Larger Wick?
शेयर करना
What should I measure? Grams per session, weighed cold on the same scale, plus pool radius at the end of each session. In the log below the candle lost 9 g, then 8, 7, 5 and 4 g across five four-hour sessions. A falling rate is the signal.
Is "extremely slow" good news for burn time? It looks like it and it is not. At 1.65 g per hour that candle projects to about 64 hours — while stranding 44 g of a 150 g fill, which is ₹29.46 of wax and fragrance per jar at listed prices. The hours are borrowed from wax the customer cannot reach.
What does "a larger wick" mean here? One step, then a change of kind. CSI lists two Eco cotton sizes — Thin (C1) and Thick (C2) — so above C2 there is no bigger cotton wick: you move to cotton braided, wooden, or two wicks. All of it burn-tested.
The session log, and what the trend says
Average burn rate is useful for costing and useless for diagnosis, because it hides exactly the information you need. Two candles can both average 1.65 g per hour: one by burning steadily at 1.65 every session, the other by starting at 2.25 and collapsing to 1.0. Those are different faults with different fixes, and only a per-session log distinguishes them.
| Session | Grams lost | Rate | Pool radius | Pool area share | Wall | What it means |
|---|---|---|---|---|---|---|
| 1 | 9 g | 2.25 g/h | 17 mm | 27% | 16 mm | Small first pool is normal in soy; do not judge yet |
| 2 | 8 g | 2.0 g/h | 20 mm | 37% | 13 mm | Pool widening, rate already slipping |
| 3 | 7 g | 1.75 g/h | 21 mm | 41% | 12 mm | Pool has nearly stalled — the wall is now structural |
| 4 | 5 g | 1.25 g/h | 21 mm | 41% | 12 mm | Rate falling with no widening: the wick is being suppressed |
| 5 | 4 g | 1.0 g/h | 20 mm | 37% | 13 mm | Pool shrinking. Heading for a drowned or self-extinguishing wick |
| Total | 33 g | 1.65 g/h | The average conceals every one of the five rows |
Two shapes, two meanings. A flat low rate with a pool that stabilised short of the glass is the classic undersized-wick-for-that-diameter picture: the wick is doing its best, consistently, and its best is not enough to cross the jar. A declining rate is different. Something is getting worse as the burn goes on — the pool is deepening and drowning a weak wick, carbon is building on the tip, the wick is being loaded by what is dissolved in the wax, or the flame has dropped below the rim into still air. The fix for the first shape is more wick. The fix for the second might be the trimmer, the oil, the dye or the jar.
The 64-hour trap
Here is why "extremely slow" is dangerous rather than flattering. Project that log forward. If the candle eventually strands 44 g of its 150 g fill — the sort of residue a 12 mm permanent wall produces — it will have consumed 106 g, and at its average 1.65 g per hour that is roughly 64 hours on the stopwatch.
| Measurement | Tiny flame · Eco C1 | Candidate · Eco C2 | Which one a customer feels |
|---|---|---|---|
| Average burn rate | 1.65 g/h, falling | 5.2 g/h, steady | Neither — but it drives everything below |
| Residue projected and weighed | 44 g | 9 g | Yes — the jar they have to clean out |
| Usable wax | 106 g of 150 g | 141 g of 150 g | Yes — it is what they paid for |
| Hours to flame-out | ≈64 | ≈27 | Only if the hours are usable ones |
| Pool reaching the glass | Never — stalled at 41% of the surface | By session three | Yes — throw and appearance both |
| Stranded wax and fragrance | ₹29.46 | ₹6.03 | Indirectly — it is margin and goodwill |
Sixty-four hours would look superb on a label. It would also be a 106 g candle sold as a 150 g candle, with a pool that never covered more than two fifths of the surface and a flame that was shrinking by the end. The number is real; what it measures is a failure. Hours to flame-out rewards every form of weakness in a wick, which is precisely why it should never be the figure you optimise.
Six things that shrink a flame that are not wick size
Work down this list before you order wicks. Five of the six cost nothing to check, and each one is a single-variable test. The rule throughout: change one thing, re-burn, re-weigh.
| # | Suppressor | How it shows in the log | The test | Cost of the test |
|---|---|---|---|---|
| 1 | Trim length — too short and the flame cannot establish; too long and it carbons and then chokes | Rate jumps around between sessions with no pattern | Fix the trim with a trimmer and repeat three sessions | ₹177 once |
| 2 | Session length — a pool that never gets time to establish rebuilds a wall every time | Pool radius resets downward each session | Burn two full four-hour sessions back to back and re-measure | Nothing |
| 3 | A drowning wick — molten wax deeper than a weak wick can lift | Rate falls while pool depth grows; flame sits low | Note pool depth as well as radius; a deep pool over a feeble flame is the signature | Nothing |
| 4 | Fragrance composition — oils differ, and composition can affect how a wick performs | One SKU behaves, another does not, on the same wick and jar | The elimination jar below, then a paired test of the two oils | ₹59.85 of wax |
| 5 | Dye loading — heavy colour can load a wick | The undyed version of the same recipe burns differently | Pour one jar with no dye, everything else identical | Nothing extra |
| 6 | Wax or wick lot, and wick position — off-centre, leaning, or a tab sitting proud | A recipe that used to work has changed with no recipe change | Re-pour from a different bag or wick pack; check centring at the pour | Nothing — or one bag |
Numbers 4 and 5 need care in how they are described, so here it is precisely. Fragrance and dye can change how a wick performs. We are not going to tell you by how much, or which oils or colours do it. No CSI fragrance or dye page publishes a dose, a burn effect or a consumption figure, and a ranking we invented would be a liability in your specification rather than a help. What is defensible is the mechanism and the method: heavy loading of anything dissolved or suspended in the wax gives the wick more to carry, and the only way to know what your oil does in your wax is a paired candle with one variable changed. CSI buyer Ashwini notes of the liquid dyes that colour depends "upon the amount of dye you add" — which is exactly the variable to pin down and record.
The elimination jar
This is the single highest-value test on the page and it costs one jar of plain wax. The logic is simple: if the wick burns normally with nothing dissolved in the wax, the wick is adequate for that jar and the suppressor is in your recipe. If it burns just as feebly with nothing in the wax at all, the wick genuinely is too small for the diameter and escalation is justified.
What to buy for the escalation
If the elimination jar sends you up the ladder, these are the three lines worth ordering: a cheap wax for the plain jar, and the two candidates that exist above Eco C2 — because above C2 the range changes kind rather than size.
| Size | Price | Per kg | 150g candles @ 8% |
|---|---|---|---|
| 1 kg | ₹399 | ₹399 | ≈7 |
| 5 kg | ₹1,996 | ₹399.20 | ≈36 |
| Size | Price | Per piece |
|---|---|---|
| Pack of 10 | ₹590 | ₹59 |
| Pack of 50 (Save 25%) | ₹2,360 | ₹47.20 |
| Pack of 100 (Save 30%) | ₹4,130 | ₹41.30 |
| Size | Price | Per piece |
|---|---|---|
| Pack of 10 | ₹120 | ₹12 |
| Pack of 50 | ₹600 | ₹12 |
| Pack of 100 | ₹1,200 | ₹12 |
| Pack of 500 | ₹6,000 | ₹12 |
| Pack of 1000 | ₹12,000 | ₹12 |
What "a larger wick" means in this range
It is worth being blunt about the shape of the range, because wick advice written for ranges with twenty graded sizes does not transfer. CSI lists six wick products. One of them has two sizes. That is the whole ladder.
| Step | What it is | Cost per candle | What must be retested |
|---|---|---|---|
| Where you are | Eco C1 single · no diameter stated | ₹5.90 | — |
| Step 1 · the only cotton rung | Eco C2 single · no diameter stated | ₹9.44 | Full-life burn, residue, throw, flame and jar temperature |
| Step 2a · count | Two Eco C1 | ₹11.80 | All of the above, plus centring and pool interaction between the two flames |
| Step 2b · kind | Cotton braided single · page targets jars over 8 cm | ₹12 | All of the above, plus trim behaviour |
| Step 2c · kind | Performance Wooden single · no diameter stated | ₹41.30–₹59 | All of the above, plus a new trim standard |
| Step 3 · count and kind | Two Eco C2, or two wooden | ₹18.88 / ₹82.60–₹118 | Everything, and a hard look at whether the jar is simply too wide for one flame |
| Cut to length | Eco Candle Wicks Loose ("2 inch diameters") · Eco Braided Wicks | ₹413–₹826 per roll | Your own cut height becomes a variable — fix it and record it |
Note what is not on that ladder: a graded series of cotton diameters. The Eco Candle Wicks page states no diameter for either size — C1 and C2 appear only as the Shopify variant names Thin and Thick — and the only two listings with numeric size language are the loose Eco roll ("designed specifically for 2 inch diameters") and Cotton Braided ("exceeding 8 cm"). So "test a larger wick" is a short list, and each entry on it is a different kind of change rather than a notch on a dial.
Where to stop, and why safety ends the argument
There is a ceiling on this ladder and it is not a performance ceiling. A wick can be too large before the flame looks alarming. The warning signs are specific and you should write them into your acceptance sheet rather than trusting your impression on the night.
| Observation | What it means | Action |
|---|---|---|
| Soot marking the glass | Incomplete combustion; the wick is delivering more fuel than the flame can burn cleanly | Step back down. Do not ship this candidate |
| Heavy mushrooming on the wick tip | Same cause; it also makes trim length unstable session to session | Step back down, or re-check the load and dye first |
| Flame that will not settle in still air | Too much wick for the pool it has created | Step back down |
| Jar too hot to hold comfortably after a session | A hazard in a customer's home, regardless of hours | Reject the candidate outright |
| Pool noticeably deeper than it was shallow-and-wide | More molten fuel standing over the wick; raises consumption and risk together | Prefer a candidate that widens rather than deepens |
And then stop at the smallest candidate that clears your wall and passes every line of that table. Not the one with the biggest pool, not the one with the best throw, and certainly not the one with the longest hours. If no candidate in the range passes both tests in your jar, the honest conclusion is that the jar diameter is wrong for the wicks you can buy — and changing the vessel is a cheaper, safer fix than forcing a flame to cross a distance it should not have to. The mushrooming and sizing interaction is covered in why is my candle wick mushrooming.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. The page you would expect from a supplier is "your flame is small, buy the bigger wick". We have written the opposite: spend ₹59.85 on a jar of plain wax and five evenings before you order anything, because half of the tiny-flame cases we are asked about are a trim, a session length or a dye dose, and selling you a wooden wick to cover one of those just moves the fault.
Every price, pack and stated specification here comes from live CSI stock in September 2026 and links to the product page, which is always authoritative. Wick size is quoted only where a page states it — the loose Eco roll's "2 inch diameters" and Cotton Braided's "exceeding 8 cm" with a 10.16 cm height. The C1/C2 page states no diameter and we do not invent one. No CSI fragrance or dye page states a dose, a burn effect or a consumption figure, and we publish none; the suppressor section gives you the mechanism and the paired test instead of a ranking. All grams, rates, pool radii, residues and hours in the worked logs are a maker's own measurements shown to demonstrate the arithmetic.

All grams per session, burn rates, pool radii, residues and projected hours on this page are a maker's own measurements used to demonstrate the arithmetic — no CSI wax, wick, dye, fragrance or jar page publishes a burn time, a burn rate, hours per gram, a dye dose or a consumption effect, and none is estimated here. Stated loads are wax formulation limits, not regulatory limits. Prices and availability change — the linked product pages are always authoritative.
