Tongs that slip, flex under load, or do not fit the crucible diameter create a serious safety risk and can ruin a casting. The Tooltos Stainless Steel Crucible Tongs are designed specifically for this task — the adjustable jaw opening covers crucibles from 2 to 5-3\/4 inches, the anti-slip jaw surface maintains grip on the curved crucible body, and the 355mm length keeps your hands clear of the furnace and the pour.\u003c\/p\u003e\n\u003cp style=\"font-size:16px; line-height:1.8; margin-bottom:1.25rem;\"\u003eStainless steel construction handles the thermal cycling of repeated furnace use without warping or corroding.

The 99.9% purity rating means minimal impurities in the graphite body, which reduces the risk of contamination in the melt and extends the working life of the crucible compared to lower-purity alternatives.\u003c\/p\u003e\n\u003cp style=\"font-size:16px; line-height:1.8; margin-bottom:1.25rem;\"\u003eThe pouring slot is a practical feature for studio use — it gives you a defined channel to direct the molten metal flow when pouring into a mold or ingot form, which improves pour control and reduces spatter compared to pouring over the rim of a plain cylindrical crucible. The three capacity options (1KG, 2KG, 3KG) cover the range from small single-piece jewelry casting to larger batch production runs.\u003c\/p\u003e\n\n\u003cdiv style=\"background-color:#fff3cd; border-left:4px solid #e6a817; padding:12px 16px; margin:16px 0; line-height:1.7;\"\u003e\nPreheat the crucible gradually before bringing it to full furnace temperature — sudden thermal shock can crack graphite. Never exceed 1300°C. Allow the crucible to cool completely before handling or cleaning. Inspect for cracks before each use — a cracked crucible can fail during heating. Always use appropriate heat-resistant tools and personal protective equipment when working with molten metal.\n\u003c\/div\u003e\n\n\u003ch2 style=\"font-size:20px; font-weight:600; margin-top:2rem; margin-bottom:0.75rem;

The flask diameter determines how many pieces you can cast in a single run and how large those pieces can be. The 2.5 inch diameter is a mid-size option — larger than 1.5 inch flasks used for single small pieces, and more precise than 3.5 inch flasks used for high-volume production. It is well suited for casting 2-4 rings simultaneously, medium pendants, earring sets, and bracelet components.\u003c\/p\u003e\n\u003cp style=\"font-size:16px; line-height:1.8; margin-bottom:1.25rem;\"\u003eThe perforations and flanged design are the two features that distinguish this flask from a plain cylinder. The perforations allow the vacuum to act on the investment from the sides of the flask, not just the top, which produces more uniform air removal and reduces the risk of porosity. The flanged rim provides a positive seal surface against the vacuum machine plate, which is necessary for maintaining the vacuum pressure required for bubble-free investment.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:20px;

The 65mm diameter and 28mm depth provide enough capacity for melting small quantities of precious metal scrap for re-casting, alloying, or refining, while remaining small enough to heat quickly in a bench-top furnace or with a torch. The round bowl shape allows the molten metal to pool centrally, making it straightforward to pour into a mold or ingot form.\u003c\/p\u003e\n\u003cp style=\"font-size:16px; line-height:1.8; margin-bottom:1.25rem;\"\u003eAlumina clay is a traditional refractory material that handles repeated thermal cycling well and does not react with gold, silver, or copper at typical jewelry casting temperatures. It is more robust than quartz for general workshop use and better suited for the bowl form factor where the vessel needs to hold a volume of molten metal rather than just channel it. The 65mm bowl is a practical size for jewelers melting scrap metal, casting small ingots, or preparing alloys for rolling or drawing.\u003c\/p\u003e\n\n\u003cdiv style=\"background-color:#fff3cd; border-left:4px solid #e6a817; padding:12px 16px; margin:16px 0; line-height:1.7;\"\u003e\nPreheat the crucible gradually before bringing it to full furnace temperature — sudden thermal shock can crack refractory materials.

The boat shape allows the molten metal to pool along the length of the vessel and makes it easier to pour or transfer the melt compared to a deep round crucible. The 87 x 9mm size is suited for small-batch precious metal work — melting scrap gold or silver for re-casting, refining small quantities of metal, or assay operations where precise small-volume control is needed.\u003c\/p\u003e\n\u003cp style=\"font-size:16px; line-height:1.8; margin-bottom:1.25rem;\"\u003eQuartz is the preferred material for precious metal work because it does not react with gold, silver, or copper at melting temperatures and introduces no contamination to the melt.
