Learn what your glazes are made of

Do glaze recipes feel like reading a foreign language to you?

Potters use all sorts of seemingly complicated and technical materials like Wollastonite, Feldspars, Nepheline Syenite, Gerstley Borate etc.

What are all those materials there for?

Many potters just weigh out these materials without having a clue why they're in the glaze or what function they perform.

I was mixing my own glazes for 5 years before I really started learning about the glaze materials I was using.

For 5 years, I had the same question that many of you have "What do the glaze materials do?"

This is the most common question I hear from potters when they first start using glaze recipes and mixing their own glazes from scratch.

In fact, I posted a survey in my Facebook group to see what people most want to learn about when it comes to glazes. Here are the results:

Glaze materials are clearly the missing piece that potters want to learn most.

A class for beginners

Understanding the role each material plays in our glaze, even on a basic level, can feel very empowering. It's the first step to understanding glaze chemistry, which opens up a whole new world of ceramic possibilities.

If you’re ready to start learning about glaze materials, then you don’t want to miss this beginner friendly class where you'll learn:

  • An overview of what glazes are made of
  • How glazes melt in the kiln
  • How each material fits into the equation
  • Different categories of materials and how materials in the same category can be substituted for each other
  • The chemistry behind each material with reference to the periodic table of elements

No experience with glaze chemistry is required, we'll start with the basics.

After you take this class, you're going to feel so much smarter the next time you're adding a material like Whiting to the glaze bucket and you think to yourself "Whiting is also known as calcium carbonate, which is a secondary flux that helps the glaze to melt."

Nerd alert! Get ready to embrace your inner nerdiness.

If you've ever looked at a glaze recipe and thought “I have no idea what any of this means” then this class was made for you!

Frequently Asked Questions

How long will I have access to the class for?

You will have access to the class and everything in your Student Dashboard for 90 days from the date you sign up. Watch it as many times as you like for 3 months.


Is this class just for cone 6 glazes?

This class is about the materials used to make glazes at all temperatures.


Will this class teach me how to mix glazes?
No, we’re just covering the function of the glaze materials in this class. If you’ve never mixed a glaze before, this workshop might not make a lot of sense to you. I recommend having at least some glaze mixing experience so you can relate to the topics covered in this class. If you want to learn to mix glazes, you can learn that in my Glaze Mixing Essentials course. This workshop is the perfect compliment to that course!


Why are the prices in US Dollars?
My students are international and USD is the most universal currency option.


What's your refund policy?
Since you get instant access to this digital workshop in its entirety, no refunds will be offered.


Your Instructor – Sue McLeod

I’ve been fascinated with glaze chemistry since I first learned to mix glazes from scratch in 2009. I really started to take it seriously when I started unloading kiln load after kiln load of runny glazes and cracked pots. I could no longer afford to not understand glaze chemistry. It’s been a passion of mine ever since and I continue to learn more and more with each kiln unload.

From 2015-2021, I worked as a ceramics studio technician at a busy public studio in Victoria, BC, Canada, where it was my job to mix and maintain large batches of glaze and fire the kilns. During this time, I was able to study the thousands of glazed pots coming out of the kiln and use my knowledge of glaze chemistry to improve many of the glazes so studio users could have more successful glaze results.

I now work out of my home studio and teach online glaze courses full time.
