I have used an iron red glaze for years now. Tested it, thick and thin. Thin
is better. My Iron Red recipe calls for bone ash. I only use original 100%
bone ash. No Tri-calcium phosphate. As soon as the mad cow scare came up I
ordered mucho pounds from a source. It looks like off white 1/2 inch
pellets. I have to put them in a mortar and pedestal and grind it down
before including it into the mix. Then sieve the whole glaze several times
to make sure it is mixed thoroughly. I use rain water. The glaze in the
final mix needs to be applied thin. About like the thickness of buttermilk.
( only southerners in the U.S. will know about the thickness of buttermilk)
Fired to cone 10 +. Cooled ever so slowly. Crystals sparkle. Killer Iron
Red.
Big red bowl www.sanantoniopottersguild.com members work. The results will
depend on your clay body. I tend to believe a lighter firing clay body
produces a extremely beautiful Iron Red glaze. Porcelain is tops!
