- Sheet: Sheet glass is a 12x12 plane of glass that comes transparent, opaque, striped. In my fish I used yellow opaque for the body, orange opaque for the tail, blue transparent for the fin, and solid blue and striped blue for the detail. - Frit: Frit glass is crushed up glass and is sprinkled on glue. For my fish I used green and blue fish around the face and body. - Stringers: A stringer is a thin string of glass like a noodle. In my fish I placed blue stringers on the end of the orange tail and in the center of the body to represent another fin. - Frit Balls: Frit balls are pieces of broken glass melted in the kiln to create a ball shape. I placed a light grey frit ball as the eye of my fish.
