Crystalline Glazes & Porcelain

June 29 - July 3


Crystalline Glazes & Porcelain

Week One (5-day): June 29 – July 3, 2020. Classes run 9 am – 4 pm daily and students are welcome to stay late in their studio.

Crystalline Glazes & Porcelain

This hands on workshop will focus on the magic of crystalline firing: glaze formulation, glaze recipes, and application both brushed and sprayed. Techniques will focus on high fire oxidation, with information about high fire reduction, reduction post firing and oxidation striking. Glazing techniques will include using encapsulated stains, and post fire acid etching.

While the kiln is firing, Ginny will be demonstrating, and participants will have time to practice, both hand building and throwing altered forms, exploring the particular qualities of porcelain: stretching, altering, joining, and cutting the clay to create pieces that accentuate the crystalline glazes. Please note: these pieces will not be part of the glaze firings.

Finally, essential attention will be paid to the post-firing finishing of the works: removal of pedestals, etching, and striking. No detail will be omitted, though of course, some alchemy will still remain: the spontaneity of crystal formations within the layers of the glaze itself.

This 5-day format allows participants to take the pieces from the beginning to the end of the process with time for experimenting in and out of the kiln. This workshop is suitable for all levels of throwing and handbuilding and all levels of glaze work.

Ginny Conrow has been a studio potter for 50 years, her work evolving from functional stoneware to sculptural/decorative porcelain, including ten years of Cone 6 oxidation and airbrushing on large wall commissions. Her pieces combine a strong interest in form, sculpting the porcelain into out-of-round shapes that are organic, sometimes almost figurative - and surface, spraying layers of glazes to accentuate the curves, shadows and mood of each piece. Currently focusing on crystalline glazes, she uses thrown, slip cast, slab and extruded elements, stretching the porcelain to its fullest.
