Your path to consistent glaze results

Do your glazes turn out how you expect them to? Have you ever opened the kiln, expecting your pots to look the same as last time, but they look completely different? They are the same glazes, fired to the same temperature. What went wrong?

There could be a number of reasons why you’re getting inconsistent glaze results. Glaze application thickness is a common reason and an easy one to get a handle on.

This course will focus on establishing the best thickness for your individual glazes, first by finding the right water content and then adjusting the viscosity by flocculating or deflocculating as required. (If these words don’t make any sense to you, don’t worry. I’ll explain in detail what these words mean and why they matter for glaze application. By the end of this course, you’ll be able to confidently use the word flocculation in a sentence!)

Once you’ve figured out the best adjustments for your glazes, you’ll have a method you can repeat as often as you need to.

Did you know that the thickness of your glaze can dramatically affect the fired appearance?

  • some glazes change colour depending on whether they’re thick or thin.
  • some glazes will run when too thick, but lose their depth and variation when too thin.
  • clear glazes can be cloudy when too thick, but feel rough to the touch when too thin.
  • some glazes won’t thin down in the bucket, no matter how much water you add.

Glaze application thickness is one of the main reasons glazes don’t turn out the same every time. measuring specific gravity, and then flocculating or deflocculting if required, is the simplest way to control your application thickness.

In this course, you will learn:

  • which tools and materials you need to keep your glazes consistent
  • how to measure the specific gravity of your glazes
  • how to decide when your glaze has enough water
  • how and when to flocculate or deflocculate your glazes
  • what to do if your glaze settles in the bucket
  • how different glaze compositions and materials behave differently in the bucket
  • other factors that affect glaze application thickness
  • systematic testing methods to get to know your individual glazes
  • how to keep the right records so you can repeat your results

I’m Sue McLeod

I’ve been a studio potter since 2010 and ceramics studio technician at a community studio since 2015.

After exploring ceramics through a mainly artistic lens for a few years, I gradually moved over to the technical side.

Learning about the materials I’m using, how they work together and the chemical reactions that are taking place has been the most inspiring part of my artistic journey. I now have a clearer path to follow and am compelled to share all I’m learning with the greater ceramics community.

I spend a lot of time studying glaze formulas, testing and experimenting to improve the glazes where I work and in my home studio.  

Having knowledge of the chemistry of ceramic glazes gives me the freedom to be more creative. It allows me to turn my inspirations into physical creations.

I believe that all ceramic artists could benefit from exploring the chemistry of their clay and glazes, even at a very basic level. I strive to take complex subjects and make them applicable and understandable to even the most “right-brained” of ceramic artists. Please join me on the glaze journey!
