The HS-7GV's 1.625-inch drop-hole allows you to load glass pieces in the chamber, heat them to melting point (typically 1500–1700°F depending on glass type), and draw controlled strings of molten glass from the bottom opening. Artists use vitrigraph glass for jewelry components, decorative stringers, sculptural elements, and mixed media work.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eCan I use this kiln for fusing or slumping when I'm not doing vitrigraph work?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eYes, when the drop-hole is plugged with a ceramic fiber plug (recommended optional accessory), the HS-7GV functions as a small fusing or annealing kiln. The 7″ × 7″ × 7″ chamber is suitable for small test tiles, jewelry-scale fusing, or pendant work. The 1850°F maximum temperature is adequate for most fusing schedules with COE 90 and COE 96 glass, though the chamber size limits project scale.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eDo I need an electrician to install this kiln?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eNo. The HS-7GV operates on standard 120V household power and plugs directly into a standard wall outlet. Confirm your outlet is on a dedicated 15- or 20-amp circuit for safe operation, but no hardwiring or electrical service upgrade is required. This makes it ideal for home studios, classrooms, or spaces without 240V access.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eWhat types of glass work best for vitrigraph in this kiln?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eCompatible glass includes COE 96 (Bullseye, Spectrum), COE 90 (Oceanside, Wissmach), and soft borosilicate varieties. Hard borosilicate requires higher temperatures than the HS-7GV's 1850°F maximum and is not recommended. Stack compatible glass colors in the chamber to create multi-colored pulls, or use single colors for uniform stringers.
