Candle Dye Calculator

Dye normally runs 0.1–1% of the wax weight. Half a per cent of 500 g is 2.5 g — a fingernail-sized piece of a dye block. Add 8% fragrance and the wax is carrying 8.5% in total, and it is that total the manufacturer's maximum load has to be compared against.

Formula

Dye = Wax needed × Dye load ÷ 100

Dye and fragrance compete for the same capacity in the wax. Deepening the colour while the fragrance is already at maximum leaves oil weeping on the surface or clogs the wick. Do not use wax crayons — the pigment particles do not dissolve and choke the wick. Coloured wax lightens a shade as it sets, so judge the colour cold, not molten.

Frequently asked questions

Q. How is Candle Dye Calculator calculated?

Dye = Wax needed × Dye load ÷ 100 — Dye normally runs 0.1–1% of the wax weight. Half a per cent of 500 g is 2.5 g — a fingernail-sized piece of a dye block. Add 8% fragrance and the wax is carrying 8.5% in total, and it is that total the manufacturer's maximum load has to be compared against.

Q. Can you walk through an example?

With Wax needed 500g, Dye load 0.5%, Fragrance load 8%, the answer is Dye 2.5g.

Q. What do I need to enter?

Enter Wax needed, Dye load, Fragrance load. The result recalculates as you type, and an empty box counts as zero.

Q. How much does the answer move if I change a number?

Changing only Wax needed (g) moves the answer to Wax needed (g) 250 → Dye (g) 1.25 and Wax needed (g) 1,000 → Dye (g) 5. The table below lays out five steps.

Q. How are the numbers rounded?

Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.

Q. Anything to watch out for?

Dye and fragrance compete for the same capacity in the wax. Deepening the colour while the fragrance is already at maximum leaves oil weeping on the surface or clogs the wick. Do not use wax crayons — the pigment particles do not dissolve and choke the wick. Coloured wax lightens a shade as it sets, so judge the colour cold, not molten.
