Should I Order Samples from Multiple Wick Series When Size Changes Alone Cannot Solve My Burn Problem?

Your situation, made precise

Here is the situation in this page's terms. You have stepped through the sizes of one wick construction (at CSI, usually Eco C1 → C2, or C2 → Cotton Braided) and the burn problem moves but doesn't go: the larger size soots, mushrooms or runs a flame that grows; the smaller one tunnels or drowns. You now suspect the construction, not the size. For the worked example we use a labelled case: your own 7.5 cm inside jar, a 150 g candle at 8% = 12 g fragrance + 138 g wax, pool area 44.18 cm². CSI lists no 7.5 cm jar, so this is your jar, measured.

Before you widen the search, check that your size test was a fair one: three candles per size, the same pour and cure, burned to the end with each third judged (the between-sizes hub sets out that matrix and the cheaper options to try first, such as a lower load or a pair). If you have already tried those, this page picks up where it leaves off.

Before you buy a basket: causes, ranked

The ranking is our judgement for "sizes bracket the jar but neither fits". User causes are free to rule out; test-design causes waste the basket if you don't; formulation causes may make the basket unnecessary.

Cause 6 is the one most worth pausing on, because it can make the basket unnecessary. Heavy, vanilla-rich or resinous oils and higher loads commonly build more carbon on the same wick (a tendency; no CSI oil page gives wick data in the text we captured). Whether to change construction or formula first is the construction-or-formula post's decision, priced both ways.

The CSI sample basket, pack by pack

CSI's wick list is short, which makes a complete basket cheap. The table is every wick construction we list, the smallest pack in stock on 7 October 2026, and whether it belongs in a basket for a 7.5 cm jar. "Unknown" means the page states no size you could place on the C1 → C2 → Cotton Braided ladder.

Argued against our own interest: you probably don't need all of it. If your size test used C1 and C2, you own them, and the basket is ₹1,416.82. If your jar is narrower than 8 cm, Cotton Braided is above your size range on its own page's wording, and one screening candle is all it deserves. And because our tabbed cotton wicks cost the same per wick at every pack, a bigger "sample" buys you nothing but stock. Wood and the roll are 80% of the basket; they are also the two most different from what you've already tried, which is why they belong in it.

One naming trap: CSI's "Eco Candle Wicks" is our own listing name. It is not another wick maker's numbered ECO series, and the sizes are not interchangeable with any of them. Similar names on different wicks are not similar wicks (the equivalent-size warning).

The construction matrix: screen, then finals

A basket of five constructions doesn't mean fifteen full-life candles. The matrix below screens one candle of each for two full sessions (the top third, where gross misfits show), then carries the survivors into finals of three candles each, burned to the end. In the worked example three constructions survive. How many you should carry forward, and how to schedule them on your bench, belongs to the candidate-count post.

When the answer isn't on our list

A basket covers every construction we sell. It can't cover what we don't. There are three honest cases where a non-CSI wick may be what your candle needs, and we'd rather name them than lose your trust later.

If you do go outside our list, the rules don't change: a new wick from anyone is a new wick, tested three candles to the end in your jar and oil, with lots compared before production. Comparing two suppliers' wicks fairly means recording more than pool width (what to record beyond the melt pool), and building a matrix that doesn't mean buying every wick you see is the wick-matrix post's method.

From basket to production

Once one construction passes its finals, production wicks = candles × wicks per candle × (1 + a defect allowance). Worked example, labelled: 300 candles a month at 2% is 306 wicks. If C2 wins: 3 × 100 + 10 = 310 for ₹2,926.40. If wood wins: 3 × 100 + 10 = 310 for ₹12,980.00, the only tabbed wick that gets cheaper per wick in bigger packs. If the roll wins: four rolls give 400 tabs for ₹2,827.28, plus your cutting time. The full formula with safety stock and lead time is the purchase-quantity post; CSI publishes no lead times, so ask on WhatsApp. Before a big order, decide how many repeats you need and write down what you're ordering (specifying a wholesale wick order), because a basket wick you can't describe is a wick you can't reorder.

Argued against our own interest: keep the spare basket wicks labelled and stored with your test records instead of using them up in production; they are your reference if a later lot burns differently (comparing a new lot with the development sample).

What to buy, and what to skip

Five items, chosen on page statements, price and stock on 7 October 2026. CSI publishes no burn or soot data, so nothing is ranked on performance, and each card says when not to buy.

Skip for now: Eco Braided and the loose 2-inch wick unless your jar is wide or near 5 cm; any 50-, 100- or 1,000-pack before finals pass; and a second basket after a clean sweep of failures. For a single candidate that only mushrooms, whether to change size or construction is the mushroom size-or-construction post.
