Cone 6 oxidation:
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 reduction:
Color darkens.
TIP:
Thinner applications will produce darker browns and reds; heavier applications will begin to show an opaque, maroon-mauve float.
