The dichroic glass cabochon for this brooch was handmade, by me, with love. It was fused in my glass kiln to very high temperatures, 1500 degrees F and annealed for strength. The brooch comprises 2 layers of carefully hand-cut fusing glass Coe 90. At the base, a layer of coloured bullseye glass. Ar the top, a patchwork generous arrangement of precious dichroic glass, richly coloured and patterned. I've included one piece of clear backed dichroic to let the base colour showthrough. The dichroic layer rather magically reflects or refracts different colours as they catch the light. Dichroic glass has to be the most perfect glass for a glass addict like myself. What I put into the kiln is never what comes out. I call it Magic. Note the word Dichroic means showing different colours when viewed from different directions. The cabachon is attached to a silver plated brooch pin back with E6000 strongest adhesive. My brooches vary slightly in size but are all approximately 3 cm x 3.5cm. I make no promise of symmetry and they are not designed to be, they are handcut glass and glass has a mind of its own and once fusing the kiln that does its own thing too. I post them out in a little white gift box as shown in the photos. You can find all my brooches by clicking the "Patchwork dichroic glass brooch joysofglass" tag on this listing. You will see that each brooch is different, very much one of a kind.
