Click to enlargeMolten Earth to Rock to Glaze (on porcelain)

4.75" x 4.5"

Red is often human's symbol for intense heat (fire), which is why I like the red glass thumbwell on this porcelain mug that's glazes with remagmized rock slurry from the Mid-Atlantic Ridge.

Interior glaze is shiny white and when sun hits the exterior, light shines thru the thin wash of Earth crust slurry.
