Pigments do not dissolve in wax. They are a suspension of particles, which needs to be stirred before pouring or dipping. Pigments are not recommended for coloring a candle all the way through; the particles may clog the wick, and/or some particles may settle to the bottom of the mold and leave dark specks on the top of the candle. It is best to reserve pigments for overdips. 1 oz. block will color approximately 16 lbs. of wax.
