Upgrade your bench setup with the F10 Straight-Back Melting Dish, a professional-grade crucible bowl engineered for precision torch-melting and hand-pouring. Measuring 77mm in diameter by 40mm in height, this compact yet heavy-duty dish features a 7.5 oz (500 gram) capacity, making it the ideal size for small-to-medium casting runs, scrap refining, and custom jewelry creation.

Whether you are working with gold, sterling silver, copper, or brass, this straight-back melting cup ensures stable heat retention and a controlled pour every time.

Key Features & Benefits

• Space-Saving Straight-Back Design: The classic vertical back design provides a stable backdrop for your torch flame, helping to pool heat inside the dish while allowing for easy manipulation with standard crucible tongs.
• Exceptional Thermal Shock Resistance: Made from a premium, clay-bonded fused silica compound, the F10 is built to withstand extreme temperature fluctuations without cracking, ensuring long-lasting durability through repeated heating and cooling cycles.
• Generous 500g Capacity: Perfectly sized to hold up to 7.5 oz (500 grams) of brass/silver (or slightly more of dense metals like 24K gold), offering the perfect balance between portability and volume for studio jewelers and hobbyists.
• Integrated Pouring Spout: Features a precision-engineered groove that prevents dribbling and ensures a steady, narrow stream of molten metal into your ingot molds, water-shott buckets, or casting flasks.

Specifications

• Model: F10
• Dimensions: 77mm Diameter x 40mm Height ($77 \times 40\text{ mm}$)
• Capacity: 7.5 Troy Ounces / 500 Grams (based on gold/silver weight standards)
• Material: Clay-Bonded Fused Silica
• Compatible Metals: Gold, Silver, Copper, Brass, Bronze, and other non-ferrous precious metals.

Preparation Tip for Best Results: Like all high-quality silica crucibles, the F10 should be properly seasoned before its first use. We recommend preheating the empty dish slowly with your torch and glazing the interior with a light layer of Borax powder to create a slick surface that helps the metal flow smoothly and prevents sticking.

Why the F10 Belongs on Your Jewelry Bench

When casting precious metals, consistency is everything. Cheap ceramic dishes can degrade quickly, introducing impurities into your metal and putting your safety at risk. The F10 Straight-Back Crucible is an industry-standard choice because it maintains its structural integrity under intense torch heat, keeping your metal pure and your pours clean. It is an essential, reliable tool for independent jewelers, dental labs, and scrap gold refiners alike.
