Ingredients:

Board with plaster lathe attached (to grip and secure the plaster to the board)
Dam is built around the board so wet plaster does not run
Large Scale collagraph plates are inked and at the ready.
Plaster of Paris, mixing bowl and rubber gloves

Method:

Once I have all my components prepared, I pour the plaster over the board (sometimes I put the plate down first and cover it with the plaster then board for different effects). The plate is pushed gently into the wet plaster and allowed to cure. The plate and board are separated, leaving the impression of the plate and ink. After it dries, I treat the “print” as an underpainting for layers of encaustic painting.
