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.

The 1KG is suited for small jewelry casting and single-piece work. The 2KG handles medium batch production. The 3KG is for larger casting runs. It is better to use a crucible that is slightly larger than your charge than one that is too small.\u003c\/p\u003e\n\n\u003cp style=\"font-size:16px; line-height:1.8; margin-bottom:0.5rem;\"\u003e\u003cstrong\u003eIs this compatible with my electric melting furnace?\u003c\/strong\u003e\u003cbr\u003eThe crucible is compatible with most electric melting furnaces rated for 1300°C or higher.

It also does not react with gold, silver, or copper at casting temperatures.

Red clay contains iron oxides which contribute to its durability and high-temperature resistance. The red clay bowls (71mm and 88mm) are larger than the white clay (62mm) and alumina clay (65mm) options, making them better suited when you need more capacity per melt.

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.

A round crucible is deeper and better suited for larger volumes. The 87 x 9mm boat is designed for small-batch precious metal work.\u003c\/p\u003e\n\n\u003cp style=\"font-size:16px; line-height:1.8; margin-bottom:0.5rem;\"\u003e\u003cstrong\u003eWhy use quartz instead of ceramic or graphite?\u003c\/strong\u003e\u003cbr\u003eQuartz does not react with gold, silver, or copper at melting temperatures, so it introduces no contamination to the melt.
