Hydrate Ridge (a Lost Seismometer Brought this Mud to Me)

4.5" x 2.75"

On porcelain, unusually fluxed lavender glaze and whether that's because of higher heat or chemistry of clay body interacting with glaze is a mystery to me. Note top exterior where white interior glaze overlaps Hydrate Ridge sediment, that mottled metallic chemistry in the sediment is revealed.
