Details Potassium Carbonate, is a white salt, soluble in water (insoluble in alcohol) that forms a strongly alkaline solution. It is the primary component of potash and the more refined pearlash or salt of tartar. Historically, pearlash was created by baking potash in a kiln to remove impurities. The fine white powder remaining was the pearlash.

Potassium carbonate (called pearlash in old recipes) was often used to harden rosin in varnish recipes, especially for use on musical instruments. It is also used to emulsify wax to make Punic wax. The recipe for making Punic wax follows:

Werner of Neustadt found the following process very effectual in making wax soluble in water. For each pound of white wax he took twenty-four ounces of potash (potassium carbonate), which he dissolved in two pints of water, warming it gently. In this lye he boiled the wax, cut into little bits, for half an hour, after which he removed it from the fire and allowed it to cool. The wax floated on the surface of the liquor in the form of a white saponaceous matter; and this being triturated with water produced a sort of emulsion, which he called wax milk, or encaustic wax. This preparation may be mixed with all kinds of colours, and consequently can be applied in a single operation.
