5 lbs. Deco Black Glaze. Cone 10 (Dry Material)
Description: A super-stable, opaque black with a nice silver crystal formation possible in the surface. It's a solid black on it own. Or, it works really well in combination with Sperry Crack Glaze. In fact, all of our Deco Colors work well under Sperry Crack. Directions below.
Mixing: Add water and screen twice thru an 80 mesh screen. Works well at 45-48 on a hydrometer.
Application: Can be dipped or sprayed. To apply under Sperry Crack: Apply it to work that's been bisque fired to cone 010 (it's still absorbent). Dip or spray Deco Black onto your work and re-bisque to cone 010. Then, dip or spray Sperry Crack it a good, medium thickness. Fire to cone 10 in an electric kiln or a gas kiln.
Firing: Cone 10 oxidation or reduction.
