Metalworking enthusiasts, this 5-piece crucible kit has everything you need to start melting and casting metals! You get 2 clay graphite crucibles (2.37\ diameter x 2.96\ height, 55ML capacity each), 2 graphite stir rods (5/16\ x 12\), and 1 graphite ingot mold (4\ x 2\ x 1\). These crucibles can handle crazy high temperatures up to 3200°F - perfect for melting gold, silver, copper, and other non-ferrous metals. The rigid construction means they heat up quickly and last 2x longer than cheaper alternatives. The stir rods help you get those bubbles out of your molten metal for better results, and the ingot mold creates nice, clean bars. Super important safety tip though - always wear heavy duty gloves and preheat the crucibles to about 500°F for 5-8 minutes before use. Whether you're into jewelry making, metal recycling, or just experimenting with home foundry work, this kit gives you professional-grade tools without the professional price tag. Perfect for use with propane melting furnaces or standard torch methods!
