The mug is the buff stoneware Plainsman M340. Firing is cone 6. On the inside is the GR6-A insight-live.com/material/1178">Ravenscrag transparent base glaze. The outside glaze is GA6-C Alberta Slip rutile blue on the outside. The transparent, although slightly amber in color compared to a frit-based transparent, does look better on buff burning stoneware bodies this.
