My Wick Bends Strongly to One Side and Creates an Uneven Melt Pool — Should I Change Wick Type or Investigate Centring First?

The free inspection: where is the wick, really?

Before anything is ordered, find out which of four quite different faults you have. Each one points to a different purchase, and two of them point to no purchase at all. Use an unburned candle from the same pour wherever you can, because a burned one has already moved.

The geometry: why a few millimetres matter

In CSI's 150 g Clear Glass Jar, the page gives about 7 cm outside; on our labelled 0.35 cm wall that is 6.3 cm inside, 31.17 cm² of pool, and 3.15 cm from a centred wick to the glass all round. Move the wick 3 mm and it sits 2.85 cm from one wall and 3.45 cm from the other. Move it 5 mm and those become 2.65 cm and 3.65 cm: the near wall is 16% closer than it should be, and the far wall is 38% further away than the near one. The near side reaches the glass first, can run hotter, and the far side may leave a ring. This is geometry, not a burn prediction, but it is why the symptom on your bench can come entirely from where the wick sits. A wick that leans has the same effect from the top: its flame stands over a point that is not the centre even if the tab is.

Measure on the inside, not across the outside of the jar; how to get the inside diameter from a listing that gives only the outside is the external-versus-internal diameter post. And if a new pack of wicks looks as though the wick itself sits off-centre in its own tab, that is an incoming-QC question for the tab-centring post, not a fixture one.

Every CSI centring option, priced per candle

The count that matters for a reusable fixture is not your monthly output; it is how many jars are setting at the same time, because each holder stays on its jar until the wax sets. So the per-candle cost below uses a worked example: batches of 10, twelve batches, 120 candles. Pour more often and the reusables get cheaper per candle; pour bigger batches and you need more of them. The double-wick version of this count is the fixture-count post.

Three things fall out of the table. First, a cheap and reliable pairing for a single wick is a sticker under the tab and a bar across the top: ₹4.47 a candle over 120 candles, with the bars still usable afterwards. Second, the steel holder is not better at centring one wick than a wooden bar; it is sturdier and it has three holes, which matters for double wicks. Third, the Wick Setting Tool is a one-jar tool: its page says "ideal for batch making", but its own method puts one magnetic base under one jar, so a batch needs one per jar. That is ₹3,990.00 for ten, against ₹336.00 for ten bars and a sheet of stickers.

What the pages do not say: none of the holder pages, in the text we captured, gives a tolerance or claims a holder corrects a wick that is already bent in its tab. A holder keeps a straight wick straight; a sticker keeps a centred tab centred. Neither straightens a kinked wick, so discard kinked ones before you pour.

The fixture-first re-pour: three candles

Re-pour three candles exactly as before, with one change: every tab stuck down at the centre with a sticker and every wick held upright with a bar until the wax sets. Your current wick is the wick under test; in the worked example it is Eco C1 from a 20-pack you already have. Burn them beside any remaining candles from the bent batch, in still air, with the same session length.

Each re-poured candle is ₹215.36 in materials including its jar and sticker (₹212.86 before the sticker); the three together consume ₹646.08. From nothing, the cash is ₹1,592.00; if you already have the oil, wax and jars, it is the fixture order alone, ₹218.00. Citrus Lemon's FAQ says "Cure soy wax candles for 48-72 hours before burn testing"; a centring verdict needs only a normal cure, because it is about where the flame stands, not about throw.

If a ring-free, straight result appears on burn 3, keep burning to about 1 cm: a centred wick that behaves in the top half can still misbehave in the final third, when heat builds. That later behaviour is a separate question (the hot-jar-near-the-end post).

When a wick-type change is still warranted

Some wicks curl as they burn; that is part of how many braided wicks are designed to behave, and a gentle curl is commonly considered normal. What matters is whether the curl carries the flame far enough off centre to make the pool uneven, consistently, in still air, after centring. If it does, test one other construction. Do not buy a construction in bulk because it is "stiffer" or "straighter" on a product photo.

For a small jar like the 150 g, CSI's options are honest but few. Eco C1 and C2 come from one listing, and the page states no construction details in the text we captured, so swapping C1 for C2 is a size change, not a type change. Cotton Braided's page describes it for "large-diameter candles exceeding 8 cm", well above a 6.3 cm jar. The realistic different construction is the Braided Wick Roll with 100 wick tabs (₹706.82), cut to your length: ₹7.07 per tabbed wick, because the 100 tabs cap the yield. How to design that A/B properly, arm by arm, is the type-swap post; how each construction compares per candle is the construction cost post.

Set those numbers beside the fixture route: the type arm costs more than the whole fixture-first re-pour, and if it wins it adds ₹1.17 to every candle for as long as you make them. That is a reasonable price for a wick that genuinely burns better in your jar. It is a poor price for a fault that a ₹2.50 sticker would have fixed. For two wicks that bend toward each other or burn unequally, the cause test is different again: the uneven double-wick post.

From a straight re-pour to the production order

Once three re-poured candles burn straight through the full life, your wick is approved as it was: keep buying the same wick on the usual formula (candles × wicks per candle × 1 + allowance; see the cluster's pilot post). What changes is a standing fixture order sized to your batch, not your month.

Reorder the stickers the way you reorder wicks: daily use × your own lead time + safety stock. They are small and cheap, so a sheet of spare stickers is better insurance than a spare pack of wicks you have not approved. CSI dispatches from Pune and publishes no lead times or stock depth; confirm dispatch on WhatsApp before a big run.

Fixtures, oil and jar: 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.

Skip for this decision: Cotton Braided Wicks (₹120.00 for 10), whose page describes them for jars "exceeding 8 cm", far above this jar; Performance Wooden Wicks (₹590.00 for 10), a different construction with its own centring needs; and the Wick Inserter steel straw (₹59.00), which helps place a wick but does not hold one upright while wax sets.
