Firing Temperature: Δ5-6
Atmospheres: Oxidation
Surface Type: Satin - Matte
Transparency: Opaque

A satin-matte slip based black glaze, great for non-dinnerware decoration. (the name is a joke on mis-reading "satin black"). The barium carbonate helps form a satin surface via crystallization.

Applied too thin- looks like tar.
Applied to proper thickness, forms a silky-satiny black.

This contains barium, manganese, and cobalt, so I don't recommend it for food-surfaces. It is stiff and makes for a great scroffito glaze. It's high clay content allows it to be painted on leather hard clay.
