This is a Level 1 class for ceramic artists who make their own glazes (or plan to) and want to better understand how glazes work. (Note: This isn’t a class about how to mix or apply glazes. Those subjects may be covered in future classes.)
To find out if this class is right for you, read the full class description here.
- What is a glaze? The basic components that make up our glazes.
- ThePeriodic Table of Elements – which elements are used in ceramics and why?
- Glaze materials and the function they perform in a recipe.
- Glass formers, stiffeners and fluxes – where they come from, why we need them and how they all work together in a glaze.
- Opacifiers and colourants – how to go about finding the colours you want?
- Cone 10 vs Cone 6 vs Cone 04 – how to change the firing temp of your glazes
- Glaze Chemistry – why we need to learn it and why it’s not as complicated as we might think.
- Unity Molecular Formula (UMF) – what it means and how to use it
- Glaze durability – what makes a glaze durable and why durability is important for functional ceramics.
- The Stull map – a guide to creating matte, satin and glossy glazes, and avoiding crazed or underfired glazes.
- Glaze Calculation Software – how to use it to analyze, adjust and create glaze recipes.
- Material Substitutions – how to substitute one material for another, while keeping the chemistry the same.
