While warm, coat the interior surface with a light glaze of Borax powder.

The deep-welled, high-back engineering of this silica crucible traps intense heat around the metal payload, ensuring a thorough, uniform melt even when using larger multi-orifice torch tips. It is an indispensable, studio-grade tool built for professional metal casting benches and high-volume refiners.\u003c\/p\u003e","brand":"Miami Jewelry Supply","offers":[{"title":"Default Title","offer_id":48769390870760,"sku":"16-216-H","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0782\/9395\/8888\/files\/CRUCIBLE20OZ.jpg?v=1784665066","url":"https:\/\/miamijewelrysupply.com\/products\/high-back-fused-silica-melting-dish-crucible-20-oz-capacity","provider":"Miami Jewelry Supply","version":"1.0","type":"link"}
