Cone 6: Speckled Plum produces a reddish brown gloss finish (one to two light coats) and evolves to deliver floating maroon-mauve tones with heavier applications (three to four coats). Heavier applications may also yield bands of reddish-mauve specks when used with certain clay bodies. While you’ll enjoy how Speckled Plum moves, the glaze will not run off your ware during a cone 6 oxidation firing.
Cone 10: Color darkens.

Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
