Instructions

A gorgeous, smooth black glaze, Silky Black plays well with others, but can be a little runny in combinations, so put a cookie underneath your work. Because this glaze is so dark, sometimes I will use it only three-quarters of the way up on the outside of a piece and line the pot with a lighter glaze that also spills out over the lip and top ¼ of the pot, overlapping with Silky Black in some interesting ways and creating a lighter visual effect overall.
