Not actually sure what clay this was. Brittany gave it to me when one of her students rejected it. Rolled out a slab, cut from a pattern (3.5" top, 4" bottom) and cut a circle for the bottom. Pulled the handle, but attached it when it had gotten a bit too dry. The matte white might be very thick inside; I'm a little worried about it!
Final note: the clear glaze did me in. I'm pretty sad about it. The studio clear caused the red underglaze to run and spatter and just got weird and cloudy on the black. The matte white inside is fine.
