Deep Yellow Matte Ink is a rich ochre color that is very rich at cone 05 and is intense under a clear glaze. At cone 5, it is less saturated and becomes muted and darker at cone 10. Like an underglaze, this Deep Yellow Matte Ink fires to a matte finish that requires a clear glaze to be considered food-safe. Too thick of an application of the ink may result in a glossy finish. Cones 05-6.
