Turbo-Aire Portable Smelting Furnace for Gold and Precious Metals

Take small-scale melting and assay work into the field with the Turbo-Aire Smelting Furnace. This portable, lightweight propane furnace is designed for rapid sample testing, helping prospectors evaluate material without sending every sample away for a separate assay.

The Turbo-Aire can melt gold in approximately 15 minutes from a cold start or 10 minutes when already hot. Its self-drafting design does not require a separate blower or regulator—simply connect it to a compatible propane tank and follow the manufacturer’s operating instructions.

Critical Safety Information

Smelting and melting metal involve extreme heat, open flame, pressurized fuel, molten metal, hazardous fumes, and a serious risk of fire or injury. This furnace should be operated only by trained, responsible adults who understand propane equipment and molten-metal safety.

Use the furnace outdoors or in a properly engineered, noncombustible workspace with adequate mechanical ventilation and fume control. Never operate it inside a home, vehicle, tent, enclosed garage, or other occupied space. Keep combustible materials, moisture, children, and bystanders away from the work area.

Always wear heat-rated gloves, a face shield, safety glasses, protective clothing, and appropriate footwear. Use properly sized crucible tongs and approved molds. Inspect all fuel connections for leaks before ignition, follow the furnace and propane-supplier instructions, and comply with applicable fire codes. Never introduce wet or sealed material into a hot crucible.

Crucibles are sold separately. Confirm that the selected crucible, flux, metal, fuel system, and safety equipment are compatible before operating the furnace.

This furnace is portable, lightweight, and fast. It’s developed to take into
the field for quick sample testing to reduce costs of several assays. It
melts gold in 15 minutes from a cold start, 10 minutes from a hot start.
No blowers or regulators needed. All you need is a propane tank. Fuel
is controlled by valve on fuel tank. Fuel hose and crucible pedestal
included. Crucibles sold separate.
