I Want to Make Knot Candles but the Wick Does Not Stay Centred Through the Curved Shape — What Wick Setup and Mould Preparation Should I Use?
Aktie
Should the wick follow the curve of the knot? No. The wick runs straight down through the thickest solid part of the knot. The curves only make that line harder to find and hold.
Why does my wick drift during the pour? Common causes are a wick that is not primed or tensioned, a pour stream aimed at the wick, a mould that bulges or whose halves shift, and a single fast pour.
Which wick should I use in a knot candle? Cut a length from the Braided Wick Roll to thread through the mould, and test Eco C1 or Eco C2 where their length allows. CSI publishes no wick sizing chart.
The wick runs straight, the knot does not
CSI does not list knot moulds, so this page assumes a silicone knot mould you have bought elsewhere. CSI supplies everything that goes into it: the wax, the braided wick roll with tabs, the bamboo wick holders, dyes and fragrance oils.
The key to a centred wick is understanding where it actually goes. A rope-knot candle is a compact mass of looping curves, but the wick is a straight vertical line from the top of the knot to the base, passing through the thickest solid part. If that line is in the right place, the flame burns down through solid wax. If it drifts even a few millimetres, it can pass through a gap between two loops, come close to an outer curve, or exit the side of the candle.
The curves cause two practical problems. They make it hard to see where the true centre is, because the top of the knot is rarely symmetrical. And the mould itself, often in two halves or with deep undercuts, can flex or shift as it fills, dragging the wick with it. Every step below deals with one of those problems.
Find the true centre before you wick
Pour one test knot with no wick at all, in the wax you plan to use. After release, look at it from above and from each side. You are looking for a vertical path, top to base, that stays inside solid wax the whole way and sits roughly in the middle of the mass. Mark the entry point at the top and the exit point on the base with a pencil.
Compare those marks with the wick hole in your mould. Many knot moulds come with a hole that is close but not exact, because the top of a knot is uneven. If the hole is off your line, you can make a new one through the silicone with a wick needle of your own at the marked point; seal the old one so wax cannot leak through it.
Wick setup and mould preparation
| What you see | Likely cause | Fix to try |
|---|---|---|
| Wick exits the side of the knot | Wick hole off the true centre line | Find the line on a test casting; move the hole |
| Wick curves into an S shape | Unprimed, floppy wick | Prime in wax and let it set straight before threading |
| Wick leans to one side at the base | No tension, or holder not centred over the mark | Tie off outside the hole and pull taut into a centred holder |
| Wick moved during the pour | Stream aimed at the wick, or one fast pour | Pour against the wall in two stages |
| Whole knot is lopsided | Mould bulged or halves shifted | Band the mould and stand it in a snug support |
| Wax leaked from the wick hole | Hole not sealed | Seal the outside with your own putty or tape |
A two-stage pour that keeps the wick still
Pour the first stage slowly against the mould wall, never onto the wick, until the cavity is about two-thirds full. A stream hitting the wick pushes it sideways, and a fast single pour sets up currents that drift it before the wax grips.
When the first pour has thickened enough to hold the wick but is not yet set, check the wick from above and the side and nudge the holder back over your mark. This is the step most often skipped, and it catches the drift that tension alone does not stop. Then make the second pour, which also fills the shrinkage hollow that forms around the wick as the knot cools; poke a relief hole near the wick first if a skin has formed.
CSI publishes no pour temperature for Soy Pillar Wax or the paraffin pellets. Read your wax with a separate thermometer, pour both stages at your recorded baseline, and keep it the same for every knot so results are comparable.
If you pour several knots at once, give each mould its own wick holder and check them in the same order every time, so none is missed at the re-centring stage. A suggested routine is to pour the first stage into all moulds, then walk back along the line re-centring each one, then top up in the same order.
Wax, wick and quantities for twenty knots
Use a pillar-grade wax, because a knot stands on its own: Soy Pillar Wax (₹600.00 per kg) or Fully Refined Paraffin Wax Pellets (₹354.00 per kg). Container waxes are too soft for its curves. For the wick, the cut braid always reaches through a threaded mould; Eco C1 (₹5.90) or Eco C2 (₹9.44) can be candidates where their unpublished length is enough, so check before relying on them. CSI publishes no wick sizing chart; burn a finished knot on a heat-safe tray, never unattended, and expect thin outer loops to remain as a shell.
The worked batch is 20 knots at a real fill of 180 g. Wax: 20 × 180 g = 3.6 kg, and a suggested 10% allowance brings it to 3.96 kg, so four 1 kg packs: 4 × ₹600.00 = ₹2,400.00 in Soy Pillar Wax, or 4 × ₹354.00 = ₹1,416.00 in paraffin. Wick: 20 × 0.13 m = 2.6 m, costing 2.6 × ₹11.59 = ₹30.13 from a ₹706.82 roll of 61 m, or ₹1.51 per knot. Wax plus wick is 180 × ₹0.60 + ₹1.51 = ₹109.51 per knot in soy, or 180 × ₹0.354 + ₹1.51 = ₹65.23 in paraffin, before dye, scent, packaging, labour, shipping and GST.
Buy this to test: Soy Pillar Wax 1 kg ₹600.00 (or paraffin pellets 1 kg ₹354.00), the Braided Wick Roll ₹706.82, a Bamboo Wick Holder set of 5 ₹118.00 and a Pen Thermometer ₹354.00. In Soy Pillar Wax that is ₹1,778.82, plus your own knot mould. Pour the unwicked test knot, then three wicked knots, and burn one.
Buy this once validated: the remaining wax for the batch and one wick holder per mould you pour at the same time. The roll from your test kit covers the wick for all twenty knots and many more.

CANDLEMAKINGSUPPLIESINDIA supplies raw materials and production equipment, not finished candles. This guide separates general candle-making practice from what CSI's own product pages state, says plainly where CSI publishes no figure (wick sizes, burn times, hardness), and labels every wick, load, test count or margin as a starting point for your own validation.
Prices are live CSI prices from October 2026; product pages are authoritative. Where a spec is not published — such as a wick size for your jar, a mould's cycle life or a wax's survival temperature — this guide says so rather than filling the gap.

Product facts (October 2026, CSI live store): Braided Wick Roll with 100 Wick Tabs (61 m): Roll ₹706.82 — cut-to-length braided wick with tabs. Bamboo Wick Holder: Set of 5 ₹118.00 — holds wicks centred while wax sets. Soy Pillar Wax: 500 g ₹300.00, 1 kg ₹600.00, 5 kg ₹3,000.00, 10 kg ₹6,000.00 — soy chunks made for pillar and designer mould candles · no fragrance load or melt point published.
Assumptions: Fragrance load is a percentage of total candle weight (200 g = 184 g wax + 16 g oil at 8%); CSI wax pages phrase their ceilings as a share of wax weight. Material cost per candle covers wax, oil, vessel, wick and dye only — it excludes packaging, labels, labour, shipping and GST. CSI publishes no wick sizing chart, burn times or wax survival temperatures, so every wick named is a candidate to test. Retail prices, budgets, margins and packaging costs are the reader's own figures. Test counts and loads are suggested starting points.
