Lithographic Crayon, William Korn, in different shapes

Lithographic crayon is made of:

  • Grease
  • Wax
  • Soap
  • Soot
  • Shellack

The proportions of these components depend on the hardness of the crayon. Shellack is not present in the greasy and soft crayons. Lithographic crayon is normally available in five different hardnesses. The lower the number, the greasier and the softer.
The crayons are used to draw the image on a lithographic stone (apart from for eample tusche and lithographic drawing ink)
