This is done by placing a piece of melted glass of one color into another piece of melted glass of a different color and then blowing the glass.The colored glass can be partly or completely etched away (through exposure to acid or via sandblasting), resulting in colorless spots where the colored glass has been removed.Flashed glass can be made from various colors of glass. A finished piece of flashed glass appears translucent.
