While Ron Roy's Licorice is beautiful, I too have been looking for a ^6
oxidation satin black glaze formula. If it were food safe, barium and
manganese free, all the better.

I think maybe asking for a manganese free black colorant at any temperature=
i=3D
s wishful thinking. You need it to balance the cobalt and iron in the mix t=
o=3D
prevent dominance by either.=3D20

I'm already using some of that in conjunction with my ash glazes, but not t=
o=3D
produce Black.=3D20
I'll give that a go.=3D20
However because I'm firing 9 +, I'm not that concerned about MgO. except wh=
e=3D
n handling it, and that's rare!
