What's Your Next Step on the Glaze Journey?

Watch this video if:
  • You know you want to learn more about glazes
  • You're not familiar with my 3 glaze courses
  • You're wondering which glaze course would be the next best step for where you're at on your glaze journey

This video was originally recorded live in Jan 2023. You can read more about each course by clicking the links below. I hope to see you in one of my glaze courses soon!

What Do the Glaze Materials Do? workshop

A beginner friendly workshop that will help you understand the role and function of each of our glaze materials. This is the first step to understanding glaze chemistry, which opens up a whole other world of ceramic possibilities.

If you’re ready to start learning about glaze materials, then you don’t want to miss this workshop where I’ll explain what glazes are made of, how they melt in the kiln, and how each material fits into the the equation.

90 Days Access

Price: $57 USD

Glaze Mixing Essentials

Learn how to mix your own glazes from scratch and do a Colour Run by testing a base glaze with multiple colourants in this online workshop.

Glaze mixing is a foundational skill that will enhance your creative potential, save you money and increase your understanding of the materials you're working with.

You'll get instant, lifetime access to the co when you register, plus an invitation to my monthly membership - The Glaze Lab - for extra support.

Lifetime Access

Price: $197 USD

The Art of Glaze Chemistry

Learn how to use glaze calculation software to analyze your glaze recipes and adjust melting temperature, change surfaces between matte, satin and glossy, and fix glaze fit issues like crazing/shivering/dunting.

Explore how base glaze composition affects colourants so you can design the unique glaze palette you've been wishing for.

This course takes a super deep dive into the science behind glaze composition so you can develop the best glazes for your work. No previous chemistry knowledge required.

Price: $597 USD

Next registration - Sept 2024

Mastering Glaze Consistency

A 4-week, online program that will teach you how to get the best glaze results possible with your existing glazes, and repeat those results from firing to firing.

Learn my step-by-step testing system for improving the consistency of your glaze application and results, and fixing many glaze flaws like running, crawling, peeling, glazes turning out the wrong colour, cloudy clears etc.

Price: $347 USD

Free Guide

Do you have these glaze challenges?

  • You don't know how much water to add to your glazes
  • You get different results every firing
  • Your glazes aren't turning out as expected
  • You can't seem to keep your glaze thickness consistent

Grab my FREE GUIDE

You'll start understanding your glaze results better when you measure specific gravity. It just takes a few simple steps to calculate the water content of your glazes and then it's easy to keep them consistent. No more guessing!

Consistent water content = consistent application thickness = consistent results.

Temperature vs Heatwork – Why We Use Witness Cones

Temperature vs Heatwork – Why We Use Witness Cones

I receive a lot of glaze questions and the first question I generally ask in return is “What did the cones look like?” Knowing whether the kiln was over- or under-fired is important for diagnosing many glaze issues. Sometimes I’m told a kiln temperature in response. But…

A Clay Reclaim Process Using a Pugmill/Clay Mixer

A Clay Reclaim Process Using a Pugmill/Clay Mixer

If you run a community studio or your personal studio is high production, you probably have a lot of clay scraps to deal with. This article will describe the clay reclaim process we use at the very busy pottery studio where I worked as technician for 6 years.

A Low Tech System for Recycling Clay Scraps

A Low Tech System for Recycling Clay Scraps

As clay artists, we’re so lucky that we can reduce the amount of waste we produce by reclaiming or recycling our unfired clay. When we make something that cracks, warps or doesn’t look how we wanted it to, we can reclaim our clay, bringing it back to its original state so…

The Air Bubble Myth

The Air Bubble Myth

There’s a common belief in ceramics that leaving pockets of air in your clay, either due to insufficient wedging or by creating an enclosed form, leads to explosions in the kiln. The belief is often communicated in these ways: “Poorly wedged clay containing air bubbles will explode…”

A Potter With a Paycheque?

A Potter With a Paycheque?

This post is based on an email I sent out this past Fall about my journey from a struggling studio potter to starting my dream job as a studio technician to reluctantly growing out of that position and quitting my job in order to teach online classes full time.

How to Measure the Specific Gravity of Your Glazes

How to Measure the Specific Gravity of Your Glazes

In this video I demonstrate how to measure the specific gravity of a glaze I just mixed using a graduated cylinder and a scale. Measuring specific gravity is a way to calculate the water content of a glaze to ensure that each time you glaze, you have the same amount of water…

Don’t Skimp on Safety in the Glaze Lab

Don’t Skimp on Safety in the Glaze Lab

Most of our glaze materials come to us in their very basic, unprocessed form.  They are dug out of the ground, impurities may or may not be removed, they are ground into a fine powder, bagged and shipped to our suppliers. Working with these minerals in their raw state poses some health risks.

How to Normalize a Glaze Recipe

How to Normalize a Glaze Recipe

When a recipe adds up to 100%, we can easily compare it to other recipes.  This is particularly useful when we have additions like colourants and opacifiers.  The base recipe remains constant while the additions are always relative to 100%. It also allows us to look at 2 recipes side by side and compare the amounts of individual materials. But what do we do if our recipe doesn’t add up to 100%?

"Understanding Cone 6" - Pittsburgh 2018

My NCECA presentation Understanding Cone 6 is all about using glaze chemistry, the Unity Molecular Formula and the Stull chart to understand how different surfaces are created at cone 6.

Which glaze formulas are likely to be matte or glossy? Which ones are likely to be crazed or be under-fired? How does flux ratio impact fired results?
