My Wick Drowns After the Second or Third Burn Even Though the First Burn Looked Perfect — What Should I Examine Before Sizing Up?

Why a good first burn can drown later

On the first burn everything is in the wick's favour: a level surface, no debris, a fresh untouched wick and no carbon. By the second light the candle has changed. Wax has shrunk as it cooled, sometimes leaving a dip or hollow near the wick. The wick carries carbon from the first burn, and if it mushroomed, a head may have broken off into the pool. Someone trimmed it, perhaps too short. Dust or a match end may have landed in the jar. And if burn 1 ran long, the pool went deep and the wax level dropped further than you think.

A wick that is too small for the jar and oil usually shows it differently: a flame that shrinks session after session, a pool that never quite reaches the glass, and a wick that gets steadily harder to keep alight. Reading that shrink as a curve, burn by burn, is the shrinking-flame post, and drowning that starts only in the bottom third, near the tab, is the bottom-third drowning post. This page sits before both: burn 1 was fine, the trouble is early, and the purchase question is whether anything should be bought at all.

The geometry matters too. Your jar is 7.5 cm measured inside. That is your own jar: CSI's three listings that state 7.5 cm (a ceramic container and two bamboo-lid glass jars) give it as a width or an unspecified diameter, not an inside figure, and all three are out of stock on 1 October 2026. It gives 44.18 cm² of pool, and a very rough rule of thumb of about 3.0 hours to a full first pool. A first burn that reached the edge in roughly that time, with a calm flame, is evidence the wick can melt this surface. That is exactly why early drowning deserves a check before a size change.

The six free checks, and what each one rules out

Run them on the cooled candle before burn 3, and on two of three candles, because one candle can carry one stray match end. None of them costs anything except a few minutes and a wick cutter or a pair of scissors you may already own.

Notice what is not on the list: a new wick type, a bigger wick "just to see", or a change of oil. Each of those changes more than one thing at once. And notice the session-length check works in both directions: if you have been running long burns, shorter sessions may cure the drowning; if you have been running short ones, the pool may never have reached the glass on burn 2, leaving a tunnel wall that later slumps into the pool. Both are about how the candle was burned, not what it was wicked with.

The release rule: when the checks earn a purchase

After the checks, relight and run one more session in still air, trimmed to about 5–6 mm. The thresholds below are our judgement, written so they can be read off a candle, not a feeling.

The release threshold is deliberately the same shape as the cluster's other size-up rules: three candles, clean conditions, the same failure on at least two. Where the failure is the opposite one, a pool that never reaches the glass even though the flame survives, the evidence for sizing up and the count to buy are in the never-reaches-the-edge post. Which symptoms justify any wick purchase at all is summarised in the cluster hub.

The up-rung order and the comparison sample

In CSI terms "one rung up" is short and specific: C1 → C2 → Cotton Braided, then pairs for wide jars. There is no sized, tabbed wick between C1 and C2, so if C1 drowns and C2 runs hot, the answer lies between two CSI rungs and the honest step is a WhatsApp question, not a guess.

Cash for the test is ₹991.80 (the C2 pack, a 100 g Roasted Coffee and a 1 kg bag of CSI 464), or ₹1,286.80 with the cutter. The six candles consume ₹746.95 of materials before your jars: ₹126.26 for each C2 candle and ₹122.72 for each C1 control, of which the wick is the smallest part. Every candle excludes labour, freight, packaging and GST.

Why the 10-pack, not the 20

For one oil, six C2 are needed and the 10-pack leaves 4. The C2 20-pack (₹188.80, the same ₹9.44 a wick) earns its place in two cases only: you are testing the up-rung in two oils at once (two × three candles plus three retained, leaving 11), or you want room for a three-candle re-pour if one candle is spoiled (11 left). Otherwise it is the same per-wick price for more wicks you have not approved.

The comparison sample: six wicks you never burn

Put three unused C1 from the pack that drowned and, when it arrives, three unused C2 from the new pack into small sealed bags, labelled with the product, the order date and the candles they went into. At cost that is ₹17.70 and ₹28.32. They earn their keep later: if drowning reappears after a reorder, burn a retained wick beside a new one in twin candles and you learn whether the wick changed or your candles did. CSI publishes no wick lot data, so your own retained sample is the reference you will have. How many to keep per lot in a larger operation is the retained-wicks post; what to measure when a new shipment looks different is the incoming-QC post; and the single measurement that exposes a changed wick, grams burned per hour, is the same-size-different-burn post.

After full life: the production order

Burn the three C2 candles to about 1 cm left. Moving up a rung fixes early drowning by adding heat, and heat commonly builds as a candle burns down, so the up-rung must also pass the final third: flame steady, nothing touching the glass, no growing pool. When to place each order against that calendar is the final-third order-timeline post. Once all three pass, size the order: wicks = candles × wicks per candle × (1 + allowance), with 5% as our worked-example allowance.

The 7-day lead time is a worked example: CSI dispatches from Pune and publishes no lead times or stock depth, so confirm on WhatsApp before a big run. The C1 you still hold is not dead stock if C1 is approved in a lighter oil or a smaller jar; use it there. Keep the retained bags with the batch records, and keep them until the candles they represent are long sold.

Before sizing up: what to buy and what to skip

Five items, in the order this decision needs them, chosen on page statements, price and stock on 1 October 2026. CSI publishes no wick-performance data, so nothing here is ranked on burn results. Oil candle counts use 12 g per 150 g candle at 8%.

Skip for this decision: Performance Wooden Wicks (₹590.00 for 10), a different construction with its own drowning behaviour (wooden wicks are commonly sensitive to pool depth and trim height); the Braided Wick Roll (₹706.82), a type change, not a size step; and any second oil "to compare" unless the release rule pointed at the oil.
