Redstone Bag (20kg)

Redstone is a fine grained, medium plastic, deep red firing, native material that vitrifies around cone 7. Suitable as a plasticity-neutral ingredient in medium and high temperature red and brown burning bodies.
Redstone is balanced enough that it can be used as-is for many applications requiring deep natural color. 
Note that Redstone contains enough soluble materials that are hostile to the deflocculation process that it cannot be used in casting slips.
