These are some examples of a fused glass technique called Fossil Vitrea that Jill and I tried. Basically, you take some organic material, e.g. leaves, flowers, weeds…anything that will burn away and is flat. Spray the material with hair spray and sprinkle glass powder in color of choice over the material. Gently remove excess glass powder (you should be wearing a mask while working with the glass powder). Carefully place the material on a kiln shelf covered with kiln paper and put a piece of fusing glass over the material. The glass is kilned to a tack fuse.
