I Have a Large Confirmed Candle Order but the Wick Has Not Passed Full-Life Testing — Which Materials Should I Delay Buying in Bulk Until Validation Is Complete?

The short answer: hold the wick, and hold whatever the fix might change

A full-life test — one candle burned, cycle after cycle, to the end of usable wax — is where wicks most often fail late: the pool that was fine at the top runs deeper and hotter near the base, the flame grows, the glass warms. Until that candle finishes, you do not know whether your current wick is the production wick. And if it fails, you do not yet know what the fix will be. That second uncertainty is the one that decides your purchasing, because different fixes change different lines of the bill of materials.

If the fix is a different wick, only the wick line changes. If the fix is a lower fragrance load, the oil quantity changes too. If no wick works in this wax and jar, the fix may be a different wax — or, at worst, a different jar, which a confirmed client order rarely allows. So the rule is not "delay everything" and not "buy everything because the order is confirmed". It is: buy the lines no plausible fix can change, delay the lines a plausible fix would change, and spend a small amount now on testing the fixes in parallel.

What each kind of failure would change

The example is a confirmed order of 800 votive candles (the order size is a labelled example) in Votive Glass Jars – Black with an illustrative 70 g fill — CSI does not publish one, so weigh a test pour — in Premium Coconut Soy Wax CSI 468 with Lemongrass and Lime at 8%: 5.6 g of oil and 64.4 g of wax per candle. CSI 468's product page states fragrance load up to 13%, a melting point of 50–53°C and pour at 58–60°C. The current wick is Eco Candle Wicks Thin C1, mid-way through its full-life candle. The matrix uses the series' retest vocabulary: KEEP, CONFIRM, REPEAT, NEW.

Two rows decide the purchasing. A wick-only fix is the commonest outcome in general practice, and it touches nothing but the wick line — so wax, oil and jars bought now would be safe. The load fix touches the oil: a lower load means less fragrance per candle. And the last row, where no wick works, can touch the wax and the jar — for a confirmed client order that is a conversation with the client, not a purchasing decision. Because you cannot know which row you are in until the candle finishes, the safest plan buys only what every row keeps.

The money at risk if you buy everything today

The wick itself is the smallest number on that table — ₹4,956.00 — which is why makers are tempted to just buy it. The bigger exposures are the wax and the oil, and they only become exposures if the fix reaches them. The 8%-to-7% row is an example of what a load fix does: 4.85 kg of oil at 8% becomes 4.24 kg at 7%, and the over-buy is the difference in the packs you would have bought. Lemongrass and Lime is ₹5.20 a gram at 500 g and 1 kg against ₹5.90 at 100 g, so the kilos carry the order either way.

Testing the fixes in parallel while the full-life candle burns

The way to protect a confirmed delivery date is not to buy early; it is to test early. While the current wick's full-life candle is still burning, pour the backup wicks so their results arrive close behind. Two backup candidates — Cotton Braided Wicks Ready Made and Eco Thick C2 — at four candles each is 8 candles, plus 3 more full-life candles of the current Thin C1 wick so you have a second and third full-life result rather than one. Wick sizes per jar diameter are not published by CSI, so these are candidates to test, not a recommendation.

The table is why a full-life result arrives later than people expect: even a small votive needs many cycles, and each needs a full cool-down. The rates in it are examples, not CSI data — weigh your own test candles. For larger jars the number of cycles grows with the wax weight, which is why double-wick candles and big single-wick jars need the full-life test started first.

The purchase plan in three stages

Stage A is the test kit, bought today. Stage B is what no fix changes, also bought today. Stage C is everything a fix might change, bought the day a wick passes. Quantities cover 833 candles poured — 825 production (a 3% reject allowance on 800) plus 8 backup-wick test candles — with a 4% pour-loss allowance on wax and oil; the 3 extra full-life candles are in stage A.

If a backup wins instead, only the stage C wick line changes: Cotton Braided for 834 wicks is 1 × 500 + 3 × 100 + 4 × 10 at ₹10,080.00; Thick C2 is 1 × 500 + 3 × 100 + 2 × 20 at ₹7,929.60. If the load drops to 7%, the oil line becomes 4 × 1 kg + 2 × 100 g + 1 × 50 g at ₹22,310.00. The votive jars are ₹31.86 each in the 10-pack and ₹35.40 singly, so the count is covered with 10-packs and singles.

When the delivery date will not wait

Sometimes the date is fixed and the full-life result will arrive too late to order and pour. Then the decision is a trade, and it helps to make it explicitly. Buy the KEEP-in-every-row lines immediately; buy the wax early if it is shared with your regular range; buy the production wick of the current candidate only if its partial burns show no warning signs; and keep the oil until the load is confirmed by at least the upper half of the full-life candle. Above all, do not ship candles from a wick that has not finished a full-life test without telling the client. The 20-day post shows how to build in remake capacity when time is this tight.

The rest of the 500–1,000 candle cluster

The single-wick post and the double-wick post size the production wick line once a wick passes; the new-fragrance post applies the same delay-what-could-change rule to client approval; the breakage post sizes the jar line; buffer logic explains why shared materials are safer to buy early; and the procurement sheet lays out the final order. If you are earlier still — choosing wick candidates for a first run — the sample-wick post sets how many to test.
