Instructor: Sue McLeod

This is a class for ceramic artists who make their own glazes (or plan to) and want to better understand how they work.

Ceramic glazes are a complex subject that often leave us scratching our heads. A recipe calls for a material we don’t have access to.  We try a new recipe and the glaze runs or crazes. We want to change a glaze in some way. Adjust the colour? Make it glossier?

When we understand our materials and how they interact with each other, we can alter our glazes to make them better.

Topics include:

  • the basic parts to a glaze
  • glass formers, fluxes & stiffeners – how they function and which materials fall into each category
  • an intro to glaze chemistry
  • the periodic table and the most common elements used in glazes
  • why colourants react differently in different glazes
  • how to determine if a recipe is ideal for functional ware
  • material substitutions
  • how to read a Unity Molecular Formula to analyze a glaze recipe
  • how to use glaze calculation software

Class is presentation style, handouts and note taking paper provided. Presentation slides will be emailed to participants after the class for future reference. There will be a visual display of test tiles to demonstrate class concepts. Includes interactive activities and time for questions and discussion.

Supply List

Bring a tablet or laptop if you would like to follow along during the last portion of the class where we learn to use glaze calculation software. (Optional)
If there is a glaze you have a question about, bring both the recipe and a physical sample. Time permitting, we will examine and analyze it as a group. (Optional)
