Lucifer Furnaces supplied Lycian Stage Lighting, a U.S.-based manufacturer of theatrical follow-spot lights, with a bench-style box furnace. The model has chamber dimensions of 6 x 6 x 9 inches and heats to 1850°F. Temperature is controlled with a Honeywell microprocessor-based digital time proportioning controller with accuracy of 0.25%. Built with 5-inch insulating brick and mineral-wool block for lower outside-shell temperature and energy efficiency, the insulation is dry fit for better refractory expansion, contraction and replacement. Seams are overlapped to reduce heat loss and increase thermal storage. A 1-inch-thick hearth plate supports the side heating elements, protects the floor insulation and provides a flat working surface.
