Skull Small Bowl. Bowls are screen printed, kiln formed glass, 5" round and about 2" high. The bottom disc of glass is cut a little larger to create a lip of color at the top edge. Because the pieces are draped over a stainless steel mold, the inside is slightly matte, creating a nice contrast with the super shiny outside. Small bowls are great for fruit, olive or nut bowls, salsas and dips, hold small trinkets and make cute decorative accents.
