Cream of Tartar

Cream of Tartar is naturally procuded during the process of wine making (fermentation). During the making of wine crystals are formed and deposited at the bottom of wine casks.

Why is Cream of Tartar used in Grandma's Approved bath bombs? This substance does a couple of things. First, it compliments Citric Acid and make the bubbling action of our bath bombs a little more vigorous. Secondly, it helps to harden the bath bomb uniformally and keep the bath bombs stable in their final shape.
