Attention metalworkers, jewelers, and blacksmiths! These Bonbo heavy-duty crucible tongs are exactly what you need for safely handling hot crucibles and molten metals in your workshop. At 26 inches long, they give you plenty of safe distance from the heat while maintaining solid control over your crucibles. The opening range adjusts from 3 1/8 inches to 5 7/8 inches, making them versatile enough to handle 3/4kg casting crucibles up to 6 inches in diameter (and they can work with up to 7 inches ideally). These bad boys are rated to withstand temperatures from 1560°F all the way up to 2912°F (that's 850°C to 1600°C for our metric friends) - serious heat resistance for serious metalworking. The heavy-duty steel construction feels rugged and durable in your hands, finished with a non-slip wax coating that protects against rust and corrosion over time. The rounded head design makes storage easy, and the grip is comfortable enough for extended use without causing hand fatigue. What's really impressive is how securely they hold crucibles - they grip the edges firmly without slipping or moving around the circumference, which is crucial when you're pouring hot molten metals like gold, silver, copper, or brass. Whether you're a beginner just getting into metal casting or a seasoned professional, these tongs are an essential safety tool for your forge or workshop. Remember to always use proper safety gear like heat-resistant gloves and eye protection when working with these tools. They're built to last through years of demanding use while keeping you safe from burns and accidents.
