Korn's Lithographic Stick Tusche can be dissolved to make liquid tusche. Simply break off a small piece and dissolve it in either turpentine or distilled water, mixing to whatever strength you need.

This makes it a versatile, economical option for artists working with tusche washes, letting you mix up only as much as a session requires. It is recommended that you silo your stick tusche – using it with either solvent or distilled water, but not together.
