Rub up separately to a fine powder, then carefully mix, and add 10 parts of dextrin and incorporate. Add 5 parts of glycerine and rub up, adding water, a little at a time, until a homogeneous viscid mass is obtained. An aniline color is produced in the material, which boiling does not destroy.

After stamping, expose to the sunlight or use a hot iron. The quantity of glycerine may be varied to suit circumstances.
