Commemorating Earth's generative nature, this sweries is all about hydrothermal vent granules. They're used as a stain in the vent-shaped area, over which I've written with a brush. Top third exterior is a dip of sediment from a NOAA designated marine sanctuary -- glaze is the Monterey Bay seafloor melted.
Interior shiny brown and exterior matte greenish are glazes assembled from refined materials. Seaglass thumbwell.
