This beautiful 19" diameter plate features rare dichroic rods that are black with a thin layer of dichro on one edge. They must first be carefully bent over a flame so that when layed on the glass they will melt in without rolling and losing the dichro edge. The dichro is in shades of blue, green, purple, and gold. The piece is 1/4" thick and has a 2" rise at the outer edge. The surface of the plate is flat. A great piece to lay flat or display on a stand.
