Top 10 Best metal smelting in 2026

Main highlights

• •Dissolves Oxides and Impurities: When used in the melting process of metals such as gold and silver, borax effectively dissolves oxides and other impurities. This action results in the formation of a fluid borate slag which floats on top of the molten metal, allowing for easier separation and ensuring the purity of the final product.
• •Versatile Uses as a Flux: Borax serves multiple roles in metalworking. It can be used to glaze ceramic crucibles, enhancing their durability and performance. Additionally, it acts as a flux in casting and soldering processes, inhibiting the formation of oxides on metal surfaces, which is crucial for achieving strong and clean joints.
• •Accelerates Melting Speed: By adding an appropriate amount of borax, the melting process of metals can be expedited. This feature is particularly useful in industrial settings where efficiency and time management are critical factors.
• •Handling and Storage Guidelines: Borax must be kept in a dry place to maintain its effectiveness. Before use, a couple of drops of distilled water can be added to the borax in a crucible. Grinding the mixture into a milky paste consistency prepares it for immediate application. Keeping the metal deoxidized during melting and pouring ensures its cleanliness and integrity.
• •NOTE: This product is Professional use only and ideal for professionals and hobbyists involved in melting, casting, and jewelry making and non-precious metals, offering ease of use and superior results.
