This course invites you to explore glaze not just as a decorative finish, but as a material with sculptural potential. Working with mid-range kiln temperatures (1200 degrees), we’ll delve into glaze chemistry, focusing on how fluidity and flow can be controlled through the careful balancing of flux ratios, melting points and additives.

You’ll be introduced to the raw materials that encourage glaze movement and transformation in the kiln. Through hands-on experimentation, you’ll mix and apply your own glaze tests, developing an understanding of how chemistry - not just heat - can drive the sculptural qualities of a surface.

Test bisqueware will be provided for early investigations, but participants are encouraged to bring their own bisqued sculptural work to glaze and fire (suitable for stoneware clays only and size limit of 10×10×10cm). The course will also cover best practices for protecting kilns and kiln furniture when working with highly fluid glazes.

What you’ll learn:

• The fundamentals of sculptural glaze chemistry

• How to adjust flux ratios and additives for movement and texture

• Methods for mixing and testing glazes with intention

• Techniques for safe kiln loading with volatile surfaces

• Application of your glaze to a personal sculptural piece

Outcomes:

• A series of clay and flux material tests

• Colour glaze experiments

• Final sculptural works finished with your own glaze formulation

Level: This course is suitable for potters and ceramic artists who have a basic understanding of glaze chemistry and can make glazes from constituent ingredients.
