These concentrated color blocks work well in paraffin, soy, palm and beeswax. The base of these dyes are made from paraffin wax and have a melt point between 120* and 130*. Depending on the wax you are using and it's opacity, a single block will color between 10-25 lbs of wax to a deep shade. Use less colorant to achieve lighter shades.
*Colors are approximate. Actual colors of the dyes will vary somewhat in each wax.
