This Frida Skull is made of fumed glass tile, black and red ceramic tile, and dichroic glass. Its framed size is 12.625” x 14.625” All my mosaics are framed and ready to hang . You can take the frame off and install them in a wall. All mosaics are on backerboard, cemented in and grouted. My mosaics are one of a kind, hand made by me.
