A Deep Dive into Crystalline & Special Effects Glazes

A Deep Dive into Crystalline & Special Effects Glazes

This workshop will provide an in-depth exploration of crystalline and other special effects glazes.  It is intended for potters with some previous experience with crystalline glazes.  Detailed discussions of new techniques and materials will be accompanied by many of Holly’s crystalline and specialty glaze recipes and tips on the use of rare earth metals.

Participants will learn about strike firing methods in both oxidation and reduction and cone 10 firing schedules, as well as process descriptions including acid etching. Holly will provide detailed information on making, glazing, and marketing, accompanied by slides of current and historical work plus commentary on studio layout and events.

There will be a hands-on glazing session on day one, with a cone 10 firing.  On days three and four there will be two more strike firings with critiques and troubleshooting on the glaze results. Participants will enjoy firing a small reduction kiln and will learn how to make this inexpensive and effective, portable fiber kiln for post fire reduction.

Holly will also demo her wheel throwing and altering techniques in porcelain while discussing forms well suited to Crystalline glazes. Expect a fun “how to” session on making Christmas ornaments and altering both cast and wheel thrown pots.

Pre-course instructions will be provided so that participants can bring along suitable cone 10 bisque pots to glaze and fire, plus some already fired crystalline pots appropriate for “strike” firing.

Each day will end with a Q&A troubleshooting session, so bring your questions for this knowledgeable Instructor.
