Crystalline Bowl

This innovative process allows you to produce macro-crystalline structures in every firing. The crystalline pattern is created by applying Seeding Media in a wash or pinpoint pattern over the Engobe, and applying Crystalline Clear over the entire piece.

Us a kiln with an electronic controller and follow our firing program to complete the process.
