Abstract: A glass photo tile is formed by edge slumping an optically-correct glass front in a mold at a superheated temperature substantially above the annealing temperature of the glass, then cooling down the edge-slumped glass front in the mold through an anneal-cooling curve followed by cooling to room temperature. A photographic print is laminated in the glass front with a transparent adhesive layer, and a back mounting is installed with an adhesive layer against a back side of the print to seal the print in the glass tile. For optically correct glass having an annealing temperature of about 1000.degree. F., the pre-heating temperature is within about 100.degree. F. of the annealing temperature, and the superheated temperature is about 1400.degree. F., and the anneal-cooling curve is a Fibonacci-formula curve. Preferrably, the photographic print is laminated to the front glass with a silicone adhesive layer, and the back mounting is a ribbed glass sealed to the print with a silicone adhesive layer.
