Speedball Underglazes are formulated to be more versatile than competitive brands. Now totaling 48 bright and bold colors, these glazes have been fired from Cone 05 -10 with vibrant results across this broad firing range! Though the new formulation provides amazing workability out of the jar, artists can easily adjust these glazes to their desired consistency, maximizing the yield of every pint up to two times to deliver an even more unbeatable value! Even better, the bold, eye-catching color of Speedball Underglazes won't be compromised, no matter how much you thin or mix them together to discover new colors, making for a happy kiln opening and studio budget every time!
