5" x 3.25"

No glaze but that which came from the inside of Earth, exploded pumice that broke through the ocean's surface, flew about and then settled back onto the seafloor where it continued morphing until humans picked it up, tightened the bucket lid and delivered it to me. Now it's melted pumice/mud on a chattered clay surface. Red glass was a gift of a manufactured tumbler.
