Bonbo Heavy Duty 26″ Foundry Crucible Tongs

The Bonbo tongs are designed for handling hot crucibles and flasks during melting and refining. With an opening range of 3 1/8″ to 5 7/8″, they accommodate 3/4 kg casting crucibles and hold crucibles up to 6″ in diameter (ideally 7″). The tool is rated for high-heat conditions up to 1600°C (2912°F), delivering a safe reach for pouring and transferring molten metals such as gold, silver, copper, and brass. Users benefit from a secure grip that minimizes movement around the crucible’s edge, reducing spill risk during critical pours.
26″ ProCast Foundry Tongs By LAIKOU

These tongs are versatile for handling hot graphite foundry crucibles and flasks used in gold and silver melting. Constructed from heavy-duty steel with a black finish, they provide a secure grip and long-term durability. The design emphasizes safe handling at a 26″ reach, enabling a safe distance from high-temperature melts. Capable of clamping 3–5 kg casting crucibles and accommodating up to 6″ diameter (ideally 7″), this tool meets professional and hobbyist needs for precise pouring and transfer of molten metals.
PMC Supplies 26″ ProCast Foundry Tongs

The ProCast 26″ tongs by PMC Supplies LLC are built to hold foundry crucibles up to 6″ in diameter. This heavy-duty option emphasizes durability and reliability for repeated use in melting and refining processes. The product notes emphasize the tool’s length, which provides a safe operational distance from molten metal, making it suitable for professional settings or serious hobby metalwork where precision and control matter during transferring and pouring.
Simond Store 27″ Blacksmith Tong

The Simond Store 27″ blacksmith tong is designed for heavy-duty use with clay graphite and graphite crucibles. The long 27″ length provides an extended reach, while a 3.5″ internal diameter accommodates standard crucible sizes. Constructed from heavy raw steel, the tool offers sturdy performance for metal melting and refining. Red sleeves on the handles improve grip safety during operations, contributing to safer handling of hot metals and crucibles during transfers and pours.
Simond Store 18″ Blacksmith Tong

The 18″ Simond Store tong is another option for metal melting and refining, offering a compact but sturdy design. It is built from heavy raw steel and includes red-sleeved handles for safe operation. While slightly shorter than the 27″ model, this tong remains suitable for smaller crucibles and precise control during transfers, making it a versatile addition to a refining toolbox.
Buying Guide: Key Purchase Considerations
Choose tongs based on crucible size, melting capacity, and safety features. A longer tong provides greater distance from high-temperature melts, reducing burn risk, while capacity and diameter compatibility ensure a secure grip around the crucible. Look for heat resistance ratings that cover your typical metal range, especially if refining gold and silver, which can require temperatures around 1000°C and above. Ergonomic handles and sleeve safety features help mitigate hand fatigue and accidental slips during prolonged sessions. Design variations include straight vs. hinged heads and curved jaw profiles, which influence gripping stability and ease of alignment when pouring molten metal.
Durability is another priority. Repeated exposure to heat, oils, and metal residues can degrade tools; choose steel alloys designed for high-temperature use and corrosion resistance. If you refine multiple metals, consider a universal tong with adjustable opening and robust clamping to handle different crucible diameters. For hobbyists, a 26″ reach often balances reach with control, while professional operations may prefer 27″ or longer for extra safety margins. Finally, verify compatibility with common crucible brands and sizes you routinely use to avoid mismatches during critical refining tasks.
In summary, the selection above provides a spectrum of options—from long, heavy-duty tongs with broad jaws to specialized 27″ models—designed to support safe, efficient metal melting and refining processes. When paired with proper safety gear and furnace controls, these tools help maintain consistent pouring, reduce crucible movement, and minimize slip-related accidents in high-temperature environments.
