Drops are a rough unit, so we give a range
Liquid candle dye is concentrated: a few drops color a whole pound. That makes it easy to overdo. Suppliers publish rates in drops per pound for a light, medium or dark shade, and the calculator multiplies those by the weight of your batch. Because a drop is not a precise unit and brands differ in strength, you get a range rather than one number. Start at the low end.
We also convert drops to grams, using about 33 drops per gram for a typical liquid dye. For batches over a few pounds, weighing dye on a scale that reads 0.01 g is more repeatable than counting drops, and it lets you write an exact recipe for a color you want to make again.
Rates we use
| Shade | Drops per lb of wax | Source |
|---|---|---|
| Light | 1–2 | Candles Molds |
| Medium | 3–4 | Lone Star |
| Dark | 6–7 | Lone Star |
| Dye block, full shade | 1 block per 2 lb soy, 1 per 4 lb paraffin | CandleScience |
Soy needs more dye than paraffin
Soy wax sets opaque and slightly creamy, so colors look softer than they do in paraffin. That is why dye block makers say one block colors twice as much paraffin as soy. If you switch waxes, expect to retest your colors.
Dye and the wick
Wick charts, including the CandleScience guide we use in the wick test planner, are tested without dye. Dye is a small amount by weight, but heavily dyed wax can make the wick burn a little differently and, at worst, clog it. If you pour dark colors, test one wick size up alongside your usual.
Before you pour the batch, spoon a little dyed wax onto a white plate and let it set for a couple of minutes. That is the color your customers will see, not the color in the pitcher.
When to add dye
Add dye to fully melted wax at the add-oil temperature, before the fragrance, and stir until there are no streaks or flecks. Dye chips and blocks take a minute or two longer to dissolve than liquid. Then add your fragrance oil and stir again.
Keeping colors consistent
Write down the exact amount of dye, the wax, the batch size and the fragrance for every color you sell. Fragrance oils themselves can have a color and can change a dye shade, especially vanilla-heavy oils that turn wax tan over time. If repeat customers expect the same color, use the same oil lot when you can.
Questions makers ask
How many drops of liquid dye per pound of wax?
Lone Star suggests 3–4 drops per pound for a medium shade and 6–7 for a dark one; Candles Molds suggests 1–2 drops for a light shade. Dyes differ in strength by brand, so treat those as a starting point and test.
How much dye block per pound?
CandleScience says one full dye block colors about 2 lb of soy wax or 4 lb of paraffin for a full shade. For pastels, use a quarter or half block.
Does dye affect the wick?
Yes. Dye adds a little material the wick has to burn, and heavy dye can clog a wick. Wick charts are usually tested without dye, so if you dye dark, you may need one wick size up. Test it.
Why does the color look different after the candle sets?
Melted wax always looks darker and clearer than set wax. Soy sets paler and more opaque. Drop a little wax on a white plate, let it harden, and judge that.
Can I use crayons or food coloring?
No. Crayon pigment clogs wicks and food coloring is water-based, so it does not mix into wax. Use dyes made for candles.
