It was a fun and unique experience when I studied with the printmaker MITCH LYONS who invented CLAY PRINTMAKING. This technique of printing uses colored clay. The plate (or matrix) is a slab of wet clay and china clay slip with organic pigments are used as the "ink". The slip is applied to the wet slab using a variety of techniques, i.e., slip trailing, stenciling, stamping, etc. to develop the design. A wooden rolling pin "the press" is rolled over a dampen paper that pulls a thin layer of colored clay from the matrix. It is amazing how many monoprints can be pulled from the same slab without re-charging the slab. The print is pulled on Pellon (a fabric used for interfacing)—and so each print has an additional texture. Here my "Guitarist" below:
