Glaze Chemistry  - Theory



Sunday October 18th
2-4:30pm
Teacher: Mila



This is an introductory course to glaze chemistry. For potters who want to understand the store-bought and studio glazes they use, or want to make their own!


We will go over the basic chemical compositions that make up a glaze, what raw ingredients are commonly used, and how to make sure our glazes are food safe. 


You will learn about different surface effects and how to achieve them by adjusting ingredients. 


We will also discuss colourants, and how they behave when combined with different ingredients, including each other.


Finally, we will look at some examples of glaze recipes and analyse them using a tool called a Stull Map.


Glaze Chemistry  - Practical



Sunday October 25th
2-4:30pm
Teacher: Mila



This is a practical class to go along with our “Glaze Chemistry - Theory” class. 

For this class you will show up with a few glaze recipes you would like to test out, found either online or in a glaze recipe book. The teacher will help you to pick one, and make any adjustments if necessary.

You will mix up a small amount of your glaze, and apply it to a test tile, which is designed to show you what your glaze will look like in different thicknesses and on different surfaces, an important skill for glaze-makers to keep track of your experiments! 

The tile will then be fired to 1240℃, logged in our database, and returned to you!
