Lithographic tusche in paste form, can of 125g.
Mixing can be made with water (distilled water ideally), turpentine or petroleum solvent.
If mixing is made in the can, one can should be used for water mixtures and a second can for solvent.
Tusche mixed with water flows easily and dries slowly.
Tusche mixed with turpentine is more viscious and penetrates deeplier in the stone. The image so produced is deeplier seated and more resistant to etching. The image prints also darker than the drawing on the stone.
