Click to enlargeMariana Trench and Havre Volcano

4.25" high x 2.75" wide

On porcelain, Havre pumice-mud glazes interior and top exterior. Below it, the chattered area is glazes with sediment from the Mariana Trench, of which I got a tiny amount, thanks to a romance of people I never met (one of whom was on the cruise).

Lower exterior is unglazed porcelain.
