Course Content

• This is a practical course in which you will be required to undertake a series of experiments, which will help you to understand the basics of glaze technology and thus help increase your overall knowledge of ceramics.

• Through experimentation, you will learn how to make basic glazes and recognise the differences between different base materials.

• By the end of the course you will have built up group of practical experiments that can be used to enhance your application of glazes.
