About Glazes

As you can see for each of the glaze recipes, I have provided photos of the pages from my glaze book. I have done this for a reason. While some of the pages are not that soiled, it is pretty easily to see that these glazes have been developed over years and through thousands of pots.

As I am able to round out this glaze section on this website, I will speak more about the lineage of glaze technology passed down over time. 

Some abbreviations you will see are:

• RIO = red iron oxide
• BIO = black iron oxide
• SIO = silica or flint
• CAO = calcium carbonate or whiting
• F4 = Kona F4 (use minspar, Kona F4 is no longer available)
• EPK = Edgers Plastic Kaolin 
• Ball = OM4
• PV = Plastic Vitrox
• Dolo = dolomite
• Neph = Nepheline Syenite
