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
