Mason 6500 Sage Gray Stain Size:1 lb. Water Absorption at Cone 04:Stains are a mixture of ceramic oxides and coloring metal oxides that are melted in kilns, quenched, ground to specific mesh size (some are acid washed), and colored with organic dyes to simulate the fired color. Essentially they are fritted colorants.
