Class Description:
This class is intended for newer members to the workshop that are making pots and using
house glazes or commercial glazes but want to mix up a small test batch of a specific glaze.
Mixing your own glaze can be quite economical and gives you complete control over the batch.
Students will bring a glaze recipe to class, and we will go over how much to make for a test
batch, how to measure and test different SG (specific gravity), how to keep good records and
lastly how to record and pay for the glaze ingredients you used. This class is intended to be a
practical hands-on day to support and encourage new members in making their first batch of
glaze.
The class will be casual, with lots of opportunities to ask questions. I will book a kiln to fire the
test tiles and then we can go over the results a few weeks later.
Required Materials:
• • Test tiles, or small test pots (no bigger than 2-2.5 inches). Small hand-built bowls work well
for this.
• • One or two glaze recipes- recommended to be from John Britts The Complete Guide to Mid-
range Glazes. But can also be from another source. I recommend that students look at the cost
of ingredients from the studio first before deciding on the recipe, as some ingredients are quite
expensive.
• • A notebook
• • a mask
• • 2-3 large yogurt containers for mixed glaze
• • gloves
• • small towel
