New is a high temperature red burning fireclay. These fired test bars show how high the iron content is, turning it bright red at all temperatures, even cone 10R (top bar). Other bars are cone 11, 10, 9 and 8 oxidation (top to bottom). Notice it does have some soluble salts that darken the color in reduction.
