Medium Blue Velvet Underglaze is a bright, primary blue. It provides a distinct color at Cone 05 and will deepen in tone at Cone 5 while maintaining its blue hue. Applying a clear glaze over Medium Blue will noticeably intensify the color at all temperatures.
Due to variations in raw materials used in the manufacturing process, we recommend firing test tiles before using each new batch (lot number) of glaze.
