Burnt Plate Oil: Burnt Plate Oils are used to lower the viscosity of the ink. Burnt Plate Oil should be added to inks sparingly as the detail of a print may be lost if the ink becomes too fluid. Burnt Plate Oil #000 has less tack and is a good match for use with Gamblin Relief Inks. Burnt Plate Oil #2 has a higher tack and is the primary oil binder for Gamblin Etching Inks.
