Instructions

This recipe is not food safe. This recipe is nice in Raku. Nice over shiny glazes. Crawly, beaded surface. Shown in the image here on top of a blue terra sigillata and Faux Lead Hulk Smash  glaze and Faux Lead Amber.

Published in "Low-Fire Surfaces" by Ronan Kyle Peterson, in the September 2017 issue of Ceramics Monthly.
Works best layered over Faux Lead glaze. It's dry, flaky, and sharp when used by itself.
