The information in this glaze course has been written with idea of synchronising practical experiments in glaze making with the theoretical knowledge of glaze chemistry. This course has been developed with my glaze teaching in India in mind, so I have kept out a lot of confusing detail and simplified the concepts where possible. During the lesson sessions additional information is given out if students require either more detail, or if a particular student's problem requires more information. The analysis of materials and results is also done blackboard style and so no notes are available.

If you intend using this information in a course please credit your source - me!

If you are using this information for your own development then good on you, and good luck with your tests.


Much of my early understanding about glaze chemistry arose through the use of a piece of software called HyperGlaze. This software analyses glazes and is immeasurably useful when learning about what materials do in a glaze and how the relationship between materials and oxides works out in a glaze. Of course much testing is still needed, but at least you have a tool that can quickly get to the heart of glaze chemistry. The tests listed above have all been initially developed using HyperGlaze although additional tweaking was done after the glaze tests were fired.

Practical Course

This practical course covers the basic ideas of experimentation and ties in with the thereoy pages. It does require access to a range of common glaze materials and equipment, including a kiln capable of reaching 1280 degrees.
