Our 1/2 oz. blocks (14 grams) are super concentrated candle dyes. Each 1/2 oz. block is sufficient to color 20 pounds of candle wax or candle gel. Please use a knife or "potato peeler" to shave off small amounts as you can always add more dye - but you can't take it away! These dyes can be blended with each other to make your own perfect shade. Don't plan on coloring large batches? Visit our soap dye page for smaller pieces - works just as well and can also be used to dye regular and gel candles.
