Kiln-Fired Art Glass by TCg. "Warm glass" is what it is formally called, as opposed to "hot glass". I hand make fused glass dishes of various sizes and shapes through a variety of techniques. I also make glass rings and pendants using art glass of compatible (COE) sources, including repurposed "hot glass", dichroic glass, brass wire, or other media. I also will present stained glass items that I have made using copper foil and solder, referred to as "cold glass.'
