The 18″ × 18″ shelf accommodates large platters, bowls, decorative panels, and jewelry components. The 10″ interior height provides clearance for most slumping molds and stacked fusing projects.

This reduces the risk of dropping expensive glass work and makes it easier to position elements precisely on the shelf. The fully-opening top provides complete access for placing large sheets, removing molds, or inspecting work mid-fire. Clamshell kilns are especially popular with artists working with full sheets of glass or heavy slumping molds.\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\"\u003eYes. The HS-18G requires a dedicated 240V, 40-amp circuit with 8 AWG copper wire. This is not a standard household circuit. A licensed electrician must install a new circuit from your breaker panel to the kiln location, terminating in either a NEMA 6-50 receptacle or a hardwired connection. Do not attempt to run this kiln on an existing circuit or use an undersized wire gauge. Improper wiring creates a serious fire hazard and voids your warranty.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eWhat's the difference between the HS-18G and other glass kilns in this size range?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eThe HS-18G includes a solid state relay as standard equipment, which many competitors charge extra for or omit entirely. SSR provides infinite power switching for smooth temperature control during critical annealing phases where precise cooling rates prevent stress fractures. The clamshell design is also less common than top-loaders in this size, offering easier loading access. Hot Shot kilns are built for technical users who prioritize control accuracy over price.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eIs this kiln covered by warranty if I buy from Peach State Pottery?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eYes.
