My Soy Candle Still Has a Narrow Melt Pool After Three Hours — Should I Immediately Buy a Larger Wick or Continue the Full Burn Test First?

The burn-1 order: one C2 10-pack, and why not more

The worked example on this page: three candles poured in CSI's Clear Glass Jar with Golden Lid (150 gram) at 8% Apple Cinnamon in Luxury Soy Wax CSI 464, each on an Eco C1 from a 20-pack. Each candle is 12 g of oil + 138 g of wax, with load as a percentage of total candle weight, CSI's convention. Burn 1 ran three hours and left a ring about 1.0 cm wide all round. You have 17 C1 wicks and 7 jars left. Here is everything the next step could need, with the smallest in-stock pack that covers each line.

The minimum order is the C2 pack alone: ₹94.40. If the bottle and bag from the C1 test are empty, a three-candle arm from nothing is ₹591.58 (C2 pack, a 50 g bottle and a 500 g bag), or ₹945.58 with a thermometer. Six candles, to allow a re-pour, is ₹1,076.16. Your jars are already paid for. The C2 wick is only 6.8% of a C2 test candle's materials (₹138.12 each, excluding the jar), so the real cost of a C2 arm is three candles, not three wicks.

If you are testing C2 rather than C1 and see the same narrow pool, the next rung is Cotton Braided Wicks Ready Made (10 for ₹120.00, ₹12.00 a wick). Its page says it is "engineered for large-diameter candles exceeding 8 cm", which is far wider than this jar. In a jar this small, our judgement is that Cotton Braided is more likely to run hot than to fix a narrow pool, so check everything in the next section first. If you are already on Cotton Braided, the next step is a double-wick arm, and the never-reaches-the-edge post covers that order.

Why three hours on burn 1 is not yet evidence

Start with the numbers. Pool area is π × r² on the inside diameter, which is geometry, not a burn prediction. The 0.35 cm wall is our labelled assumption for turning the page's outer rim figure into an inside figure.

So a 4.3 cm pool at three hours is a real signal. It is past the rough 2.5-hour mark, and it is inside the 3–4 hour band many makers use for a first burn. It is not yet a verdict, because the first burn of a soy candle is the one most often affected by things that are not the wick. The checklist below is free, and every item on it can narrow a pool by itself.

Then burn twice more and log each candle the same way: ring width at north, east, south and west each hour, pool depth, and trimmed flame height. The four-point log and the catch-up rule are in the 6 cm first-burn pool-log post. Whether a pool that only reaches the glass at about three hours is acceptable is covered in the 7 cm three-hours-to-the-edge post. This page does not repeat their methods. It owns what you buy while they run.

What burn 3 will tell you, in purchase terms:

Burn 1 to burn 3: what a spare pack buys you in days

The timeline above sets four ways of ordering against the same three C1 candles. The burn days are a worked example: poured on day 0, cured three days, one three-hour burn a day. The 6-day lead time is a placeholder for yours. CSI dispatches from Pune and does not publish delivery times, so confirm dispatch on WhatsApp if a date matters.

Option C is this page's answer because it costs least for the days it saves. Option D is the right call when the calendar is tight, for example a Diwali run with no slack, and the three extra candles are cheaper than a missed date. The parallel-run plan, keeping one test going while starting the next rung, is set out for a 10 cm jar in the 10 cm continue-or-change post; the logic is the same at 7 cm. Option B is honest if money is tight and the date is not. Option A has no case that C doesn't beat: same days, ten times the cash, and the same price per wick.

One more reason to hold the pack rather than pour it on day 0: a C2 arm poured before you know why the C1 pool was narrow may share the same cause. If the room is draughty, both arms tunnel on one side and you learn nothing. Fix the free items first, then pour.

Which symptoms usually justify a wick purchase

This cluster runs from a narrow pool to a hot jar. Grouped by what they usually lead you to buy, the symptoms fall into five families. "Usually" matters: each needs its own evidence, and the capstone systematic diagnosis before buying turns this into a full decision tree with thresholds. Here is the short version, with what each family's purchase typically costs at CSI's smallest in-stock pack.

Two things stand out. The cheapest family, "buy nothing yet", covers the most symptoms, and that is not an accident. Many wick complaints come from how the candle is burned, trimmed or cured rather than from the wick. And none of the purchase families starts with a production pack. Every first purchase is a test quantity, because a symptom tells you which direction to test, not which wick will pass. Every line in the map below links to the post that owns one symptom's purchase decision.

If burn 3 confirms: pouring the C2 arm

You are here because all three C1 candles still leave a ring at burn 3 and it is not shrinking. Pour the arm that day.

The approval rule is the series rule, stated in full in the 8 cm ladder hub: Gate 1 at burn 3 screens, Gate 2 at the full life approves, and only Gate 2 releases a production order. Two notes specific to a narrow-pool start:

Closing the bracket from above. If C2 passes, you know C1 fails below it, but not what happens above. A chosen wick is most trustworthy when it sits between a documented fail on each side; the rule and its logic are in the 7 cm adjacent-sizes post. In CSI's range the rung above C2 is Cotton Braided (10 for ₹120.00). Three Cotton Braided candles poured with the C2 arm cost one more pack and three more candles. Our judgement: if this candle is heading for production, close the bracket. If it is a one-off gift batch, many makers accept "C1 short, C2 passes full life" and move on.

If C2 overshoots. If C2 reaches the glass in under an hour with a tall flame or a pool well past 1 cm deep, the answer may lie between C1 and C2, where CSI has no sized, tabbed wick. Say so on WhatsApp rather than forcing a choice. The fast-and-deep post covers the down-step and the bottom of CSI's range.

After approval: sizing the C2 production order

When all three C2 candles pass the full life, size the order from your own production: wicks to buy = candles × wicks per candle × (1 + allowance). The allowance covers rejects and retests; 5% is our worked-example figure. Because C2 costs ₹9.44 a wick in every pack, choose packs that add up to the number and nothing more.

The C2 line is small next to the oil (₹1,585.92 against ₹9,107.71). That is the point of the whole cluster: a wrong wick is cheap to buy and expensive to pour around. Moving from C1 to C2 adds ₹3.54 a candle, ₹566.40 a month at this volume. That is a fair price for a candle that reaches the glass, and no reason to stretch a C1 that doesn't.

Reorder point and safety stock

A reorder point is daily use × your lead time + safety stock. In the worked example, 168 wicks a month is about 5.6 a day; with a 6-day lead time and five days of safety stock, reorder when you are down to about 62 wicks. Both figures are yours to set; CSI does not publish lead times or stock depth. Per-SKU reorder points across several wick sizes are worked through in the 500-candles-a-month reorder post. Keep the drawer habit too: one small pack of the rung on either side of each approved wick turns the next narrow pool into a same-day test.

The five items behind the burn-1 decision

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.

Skip for now: Performance Wooden Wicks (₹590.00 for 10) are a different construction with no widths to step between, so they don't help a narrow-pool decision. The Braided Wick Roll (₹706.82) is unsized cut-to-length braid; it belongs in a type-swap test (the tall-flame post), not a rung step.

Map of this cluster: 5541–5560

This hub owns the cluster's short answer: don't order a larger wick after one burn, but keep the next rung's smallest pack on hand. It also owns the five-family list above. Each other post owns one symptom's purchase decision: what to buy, how many, which pack, and when to stop buying.
