The Middle Glazes

The Story Of Mid-Temperature Glazes

Workshop Overview

The Middle Glazes is a comprehensive, 54-part study into Mid-Temperature glazes. Also known as Cone 6 or Cone 5-6, these glazes are one of the most popular firing temperatures in ceramics. They can be beautiful, enticing, engaging and incredibly frustrating. In this workshop we will explore in depth, what we know to make the most out of Mid-Temperature glazes.

We will take the mystery of materials, formulas and firings and translate them for real working artists. Some of the topics we will explore: What is a glaze?, What is Cone 6?, Chemistry basics, Glaze chemistry, Materials, Understanding glaze formulas, Understanding cone 6 formulas, How temperature works, Glaze mapping (prediction), Matte glazes and fake matte, Glaze durability, Converting Cone 10 glazes, Effects, Identifying Cone 6 glazes, Altering glazes, Problems with Cone 6, and even more! Join us and we will change your work, forever.

What Students are Saying

★★★★★

“I have just finished your Middle Glazes online workshop, and wanted to drop you a line to say thank you. Matt, I will miss you talking to me on my screen – but more importantly, I have learned so much! I have a totally new approach to glazes (and clay bodies) and so many insights… now I just need to put them into practice, and try and remember all the amazing things I have learned. I am busy printing out reminders to dot around my studio!”
