- Understanding Glaze Basics - Glazy
Glaze is essentially a specialized glass formula engineered to melt and fuse onto clay at certain temperatures It makes ceramic ware waterproof, more durable, and visually appealing Without glaze, many ceramic pieces would be prone to leakage, staining, or rapid wear
- Major Oxides in Glazes - Glazy
When you mix a glaze, you’re combining several powdered materials, each of which contributes certain oxides to the final melt These oxides determine how easily the glaze melts, how fluid or matte it becomes, and how it ultimately looks and behaves on your fired pieces
- Material Substitution in Ceramic Recipes - Glazy - Glazy Ceramic Glaze . . .
Step-by-step guidance on swapping raw materials in your glaze or clay formulas, from easy one-to-one replacements to more complex multi-oxide adjustments
- Glazy Ceramic Glaze and Pottery Recipes
If you've got a glaze that you work a lot with, it can be an interesting exercise to do a Stull chart for it, both at your usual firing temperature, and 50 or even 100C higher and lower View more Derek Au
- Common Glaze Defects - Glazy
Here’s a test with a fixed glaze and variable body showing how the composition of the body can affect glaze fit The glaze is Pinnell Blue Celadon (a fairly low-expansion glaze that does not usually craze on porcelain bodies), while the porcelain is a typical high-fire body with Red Iron Oxide (RIO) successively added in 1% increments
- Chemical Analyses and Formulas in Ceramics - Glazy
To understand or adjust how a glaze fires, we track these oxide “ingredients” using percentage analyses and formulas They help us foresee whether a glaze will melt fluidly, stay matte, fit the claybody, and so on
- Introduction to Glaze Calculation - Glazy Ceramics Wiki
The purpose of glaze calculation is to determine the total amount of each element present in a glaze, and the proportions relative to each other With that information at hand, it is possible to calculate materials substitutions, revise melting points, and do other useful calculations
- Clay Glaze Types - Glazy
Learn about different glaze categories based on color, composition, and firing characteristics A comprehensive guide to categorizing ceramic materials, including clay bodies, glazes, slips, and engobes
