Glaze Chemistry 101

10 Week Glaze Chemistry 101 Course

In this course you will learn basic glaze chemistry – why glazes do what they do – what works, why it works, and why it doesn’t work.

You will learn about the raw materials, fluxes, colourants, opacifiers, and more

Glaze faults, why and how to correct them

Basic formulation and bucket level testing

Different types of glaze – atmospheric conditions, firing cycles, temperatures, and more….

The next course will be in 2020.
