How Do I Determine Whether a Candle Needs a Different Wick Because of Fragrance Chemistry Rather than Jar Diameter, Wax or Manufacturing Variation?

When you need the kit, and when you don't

Attribution earns its cost when more than one thing could explain the failure. The worked example is the cluster's 200 g jar: your own, 8.0 cm across the inside on your approved jar lot, filled to 200 g at 8% (16 g of oil + 184 g of CSI 464). CSI does not list a jar at 8 cm. Dark Vanilla was approved on C2 months ago; now, after a new jar delivery and a fresh wick order, its candles tunnel at burn 3. Three things changed at once: the jars, the wick pack and, quite possibly, nothing about the oil at all.

Argued against our own interest: the quick alternative, a Cotton Braided 10-pack and three Dark Vanilla candles on it, is ₹815.28 (₹12.00 a wick, ₹695.28 of candles), against ₹2,575.12 for the kit's twelve. It is the right move when only the oil changed. It is the wrong move when the jars did, because it buries a jar-lot problem under a bigger wick: move a whole 300-candle month to Cotton Braided to mask it and you pay ₹768.00 more a month in wicks for a fault that sits in the glass. How to organise jar effects and fragrance effects across a whole launch, with anchor rows and columns, is the three-jar, eight-fragrance post; this page is the one-order version for a single failing candle.

The attribution kit, line by line

Three details matter more than they look. The wax comes from one bag, so wax is held constant across every cell; CSI publishes no lot data, so if you are buying fresh wax, buy a single 5 kg bag (flat per gram with the 1 kg, so it costs nothing extra per gram) rather than three separate 1 kg bags. The suspect pack A must have nine wicks left; production packs of 50 or 100 usually do. And the seven unused wicks of pack B stay sealed and labelled with the purchase date, because if the pack arm turns out to explain the gap, those are your evidence.

The optional wax arm adds three Dark Vanilla candles: three more wicks from pack A, 48 g more oil (two 100 g bottles, ₹1,580.00, cover all twelve Dark Vanilla candles with 8 g left) and 552 g from the second wax bag: ₹687.60 more in materials. Pour it only if a new wax bag is among the things that changed.

The four cells and what each one rules in or out

Read the oil arm carefully. If Eucalyptus Spearmint also tunnels in the suspect pack and jars, the oil is not the explanation: something in the setup has changed for every oil. If it passes while Dark Vanilla fails, the oil matters in this setup, but check the jar and pack arms before concluding it is the only factor: a wider jar can push a heavy oil over the edge that a light oil still clears. Vanillin-rich and dark gourmand oils are commonly linked to wanting more wick: a tendency the oil arm tests rather than assumes.

Manufacturing variation is not an arm of its own; it is read from the spread inside every cell. Three candles that agree mean the cell's result is about its parts. One of three failing means something varied between candles: a wick off centre, an air pocket, a draught on one side of the table. That is why every wick is held by its own centring device while the wax sets, and why a split cell is re-poured rather than interpreted. A draught test that separates room effects from wick effects is the ceiling-fan post; if a wick leans in the set candle, centring comes before any purchase (the leaning-wick post).

Running it: one pour, one bag, one room

Twelve candles in matched sessions is a lot of burning. If you are short of time, the cells can be screened at burn 3 and only the deciding cells (the control and whichever arm differed) taken to full life. Separating a three-arm attribution for soot rather than tunnelling, so a label or load problem doesn't trigger a wick purchase, is the soot-attribution post.

Which variable explains the gap, and what to buy next

The last row is the most common real answer: the heavy oil and the wider jar together, neither alone. The kit's value is that it shows you the choice instead of making it for you. If you keep the wider jars, each oil's wick is a question again, which is the new-jar post; if you go back to the approved lot, nothing needs buying. And if the gap follows the wick pack, the measurements to record on any wick delivery are the incoming-QC post, and keeping retained wicks from each lot is the retained-wicks post.

For the oil-is-the-cause outcome, the purchase is small and bounded. Cotton Braided costs ₹2.56 more per candle than C2 and is ₹12.00 a wick in every pack, so the 10-pack covers the three-candle confirm with seven spare. The cluster's planning view, expect one or two wick builds across a range and buy for two, is the cluster hub.

Whatever the kit points to, production quantities come only after the full-life pass, by the series formula: candles × wicks per candle × (1 + allowance), from the series hub. Worked example: if Dark Vanilla moves to Cotton Braided at 60 candles a month with a 5% allowance, that is 63 wicks a month, covered by a 50-pack and two 10-packs (₹840.00), at the same ₹12.00 a wick as the 10-pack. If the cause was the pack, the jar or the process, your existing C2 order simply continues; CSI does not publish lead times or stock depth, so confirm dispatch on WhatsApp before a big run.

What to buy, and what to skip

Four items, chosen on page statements, price and stock on 1 October 2026. CSI publishes no wick-performance or lot data, so nothing here is ranked on burn results. Oil candle counts use 16 g per 200 g candle and 12 g per standard 150 g candle.

Skip for attribution: Cotton Braided Wicks (₹120.00 for 10) until the oil arm points at the oil. Steel Wick Holder (₹250.00 for 5): a single-wick candle needs only the one-hole centring device. A second jar size or a new wax: each adds a variable the kit is designed to remove.
