Because the liquid color is consistent with the fired color

Mason 6388 Mazerine Blue Stain Brushes Pyrophyllite is a hydrated aluminumStains 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. They are made and manufactured for several reasons: to provide a consistent and stable form of colorant that doesnt dissolve in the glaze melt as easily as coloring metal oxides; to make colorants safer
