Both pieces have a transparent glaze, G1947U. The Fire-Red (a blend of Plainsman A1/M2 and St. Rose Red) was mixed as a slurry, dewatered to plastic form and then wedged in to the B-Mix (left piece has 10%, the other 20%, the bar in front shows the pure material). The A1 supplies most of the speckle, the St Rose and M2 impart the color. This addition does not affect the working properties of BMix (it still throws very well). An added benefit is that pieces dry better. Fired strength and maturity are minimally affected (porosity stays around 1%). With a 20% addition the surface of the unglazed clay is almost metallic. Silky matte glazes, like g2571a, are stunning on a body like this.
