How Do You Melt Down Black Soap?
To melt down black soap, start by breaking it up into small pieces. Place the pieces in a double boiler or a heat-proof bowl over a pot of simmering water. Stir the soap occasionally until it melts completely. You can also use a microwave to melt the soap by heating it in 30-second intervals, stirring in between, until it has melted. Once melted, pour the soap into a mold or container and let it cool and harden before using.
