Some Pre-Tabbed Wicks Are Not Standing Straight — Will That Affect Centring and Burn Performance Enough to Remove Them From Production?

Four kinds of lean, four different decisions

Pre-tabbed wicks travel in bundles and packets, pressed against each other for days. Some arrive slightly curved simply because of how they were packed. Others lean because of how the braid was fixed into the tab in the first place. From a distance the two look the same. On the pouring table they behave very differently.

Before deciding anything, stand a few on a flat, hard surface such as a ceramic tile and look at them from the front and from the side. The tab should sit completely flat. Then follow the braid from the neck upwards. Where the lean starts tells you most of what you need to know.

The key distinction is between damage to the braid above the tab and a fault at the tab itself. The first is usually recoverable. The second is built into the wick.

Why a lean matters for centring and burn

A candle burns where its flame is, not where its tab is. If the braid tip sits off the jar centre, the melt pool grows unevenly: one side reaches the glass early while the other side lags. You see a crescent-shaped pool, wax hanging on one wall and, in narrower jars, extra heat concentrated on the glass nearest the flame.

The awkward part is that a tilted-crimp wick can look perfectly straight in the finished candle. The holder kept the top centred while the wax set, and the wax holds it in place. It is only later, often in the lower half of the burn, when the wax around the neck melts, that the wick relaxes back to its built-in angle. By then the candle is in a customer's home. That is why this page's decision is made at goods-in, not at the pouring table.

Your jar decides how much lean you can live with

The same small lean matters more in some jars than others. In a narrow jar, such as the 120 g shiny jars CSI lists at 6 cm diameter, the flame is already close to every wall; a wick tip sitting a little to one side can bring the flame near enough to the glass to create a noticeably hotter patch. In a wide jar the same offset is a smaller share of the distance to the wall, and the pool may even out over a few burns.

So set your acceptance line per jar, not per wick. A practical approach is to write down, for each jar you pour, how far off-centre you would accept a wick tip to sit when the tab is flat, then check sampled pieces against that. Treat any figure you choose as a suggested starting point to validate with burns in that jar, and tighten it for your narrowest vessels. It also means a lot that fails for your smallest jar can sometimes be released for a wider one, provided that jar has its own proving burn.

If you are unsure where your narrowest jar's limit sits, test one candle with a deliberately leaning wick and one with a straight wick side by side, attended, and watch the glass and the pool shape. It is a cheap way to learn how forgiving that jar is.

A goods-in stand test and set-pour proof

That last step is the one that proves your straightening works. If straightened wicks stay central after the holder is removed and through the lower half of the burn, you can release that category with confidence. If they drift, reclassify them with the tilted crimps.

Worked example: sorting a sample and planning holders

You sample 200 pieces from ten packets. The count comes out at 176 straight, 18 with a bent braid, 4 with a tilted crimp and 2 with a bent tab or kink. Tilted crimps turned up in three different packets, so you decide, as a suggested rule, to stand-test the whole carton rather than rely on the sample.

Straightened pieces need support while the wax sets. If you pour 40 candles in a session and want every one held, not just the straightened ones, you need 40 holders. CSI's bamboo wick holders come as a set of 5 for ₹118.00, so 40 ÷ 5 = 8 sets, and 8 × ₹118.00 = ₹944.00. They are reusable, so that is a one-off cost that supports every future pour, not a charge against this carton.

Six removed pieces out of 200 may not sound like much. But if tilted crimps appear across several packets, the rest of the carton almost certainly holds more of them. A full stand test is a morning's work; a lopsided candle in a customer's home is a review you cannot take back.

The release decision and the supplier conversation

Release the straight pieces. Release the straightened pieces once your set-pour proof passes, and keep them labelled separately until it does. Remove tilted crimps, bent tabs and kinks from production for good; do not hold them back for a quiet day when someone might be tempted to use them.

Then tell the supplier, with numbers. Send the counts by lean type, photographs of each type standing on a tile beside a ruler, and your invoice reference. Bent braids point to packing; tilted crimps point to the tabbing step. Both are useful for a supplier to hear, and a clear report is more likely to get a clear answer. If the wicks came from CSI, message us on WhatsApp (+91 7397976926); the same rule applies to us as to anyone else, and the reply belongs in your goods-in record.

Finally, never leave a test candle burning unattended, and if any test jar shows a chip or crack, take it out of production along with the wick that was in it.
