Color Pastes are ready-to-use water-based, totally inorganic, pH-Acidic pastes that allow foundries and molten metal processing facilities to add color to their operations.  Can be used for adding labels, marking, coding, logos or identification to your ceramics with use temperatures up to 800 C and to metals up to 500 C.  Can be applied by trowel, spatula, putty knife, squeegee or, more conventionally, by brush or roller, and even by pressure-fed air-spraying.  Coating is applied and dried at room temperature, and is then ready to be used in a high temperature environment.  Note that thinner coatings generally give the best results. Black, White, Red, Yellow and Blue will mix to make a nearly infinite number of colors.
