This Multi Colored Cross is made of fumed glass tile, and dichroic glass. The fumed glass and the dichroic glass change color as ambient light shifts. It’s framed size is 11” x 14.5” 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.
