I Want to Make a 500 g Three-Wick Luxury Candle — How Do I Choose the Wax, Fragrance Load and Wick Spacing Before Buying Materials?

The spacing geometry, worked from your own measurement

What you can do is reduce the problem to one decision. Three wicks sit on a circle concentric with the jar. Choose the radius of that circle — call it r — and two consequences follow immediately and exactly. The distance between neighbouring wick centres is r × √3, because three equally spaced points on a circle form an equilateral triangle whose side is r√3. And the clearance from each wick to the glass is the jar radius minus r. That is the entire geometry. There is no third number to look up.

Those two consequences pull against each other, which is why the choice of r is a real decision rather than a formality. Push r outward and the wicks separate — good, because three flames too close together behave as one hot centre — but they approach the glass, and a flame sitting near the wall heats that wall. Pull r inward and the wicks clear the glass comfortably, but their pools merge early and you have built an expensive single-wick candle. The table below sets out the trade at a measured inside diameter of 10 cm.

Notice what the fourth column is telling you. The per-wick share is fixed by the jar, not by the spacing. Whatever you do with r, each of three wicks in a 10 cm jar is being asked to do the work of a single wick in a 5.77 cm jar. That is the single most useful sentence in this guide, because it converts an unfamiliar problem into a familiar one: you are not choosing a "three-wick wick", you are choosing three wicks each suited to roughly a 5.8 cm candle, and then deciding where to put them.

Why spacing is the fourth decision, not the first

Most makers arrive at this brief with the spacing question first, because it feels like the technical one. It is actually the most dependent variable in the build. The house order for this series is container → wax → fragrance and load → wick → dye, and every step of it is a constraint on the next.

The container fixes the diameter and the fill, which is why measuring comes before everything. The wax fixes the load ceiling and the pour behaviour: CSI 468's stated pour band of 58–60°C is far lower than the 70–80°C of Luxury Soy Wax Chunks or the 80–90°C stated on CSI 464, and on a 500 g pour that changes your timing, your working window and how the surface sets. The oil fixes its own, usually lower, ceiling, and it changes how every wick in the jar draws, because oil is fuel. Only with all three settled does the wick question have a stable answer — and only then does spacing, which is a property of the wick layout, mean anything. Dye is last because it is the easiest thing to change and the most likely to disturb a wick you have just proven.

Get that order wrong and you will re-test. Choose a spacing first, then change the wax from CSI 468 to a soy with a different pour band, and the pools form differently, merge at a different time and reach the glass at a different rate. Change the oil and the same thing happens again. On a 540 g candle each of those re-tests costs ₹831.80 of materials plus two weeks of cure, which is the real argument for doing it in order.

The material specification for a 540 g three-wick candle

This is the table to shop from. Quantities are for one candle and for the three-candle test that proves it; every rupee figure is a live September 2026 listing or a computation shown in full.

Two ceilings, and how 40 g of oil is arrived at

All arithmetic in this series follows CSI's own wording: load is a percentage of total wax weight. That convention makes a 500 g three-wick candle unusually tidy. Five hundred grams of wax at 8% is exactly 40 g of oil, for a 540 g finished candle — which sits inside the jar page's stated 500–600 g band with room to spare. On the other convention in circulation, load as a share of the finished candle, the same candle reads as 7.41%. Both numbers describe one candle; mixing them silently across a recipe is how a formula drifts by a full percentage point.

The last row is the whole point of the section. CSI 468 states up to 13%. Sage and Cedarwood states up to 10% for soy wax. Those two ceilings disagree, and the lower one governs — every time, without exception, and regardless of which page you found first. It is also worth saying what a silent page means: Eco Soy CSI 400 states no load at all, and that is not permission to use the oil's 10% either. A silent page means you hold at 8% and prove it.

What to buy for the first three-wick test

The three-candle spacing test

Three candles, one variable each, all cured together. The variable is deliberately not the spacing in the first round — it is the wick, because a spacing that fails with the wrong wick tells you nothing about the spacing.

The costed basket, and what the rounding costs

You cannot buy 1,575 g of wax or 126 g of oil. Here is the basket rounded to the packs CSI lists, with the leftover priced so you know exactly what the rounding is costing you.

The leftover oil is the line worth looking at twice. Buying two 100 gm packs leaves 74 g of Sage and Cedarwood worth ₹515.19 sitting on the shelf, which is not waste — it is your second round. Do not solve it by buying the 500 gm pack: that is ₹2,584.20 to make 126 g of candles, even though the per-gram rate falls from ₹6.962 to ₹5.1684, a saving of ₹1.79 a gram that only pays back once you are pouring regularly. The 500 gm pack is the right buy after the formula passes, not before.
