Review: Good - Just what I needed for silver ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #4,951 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #22 in Jewelry Casting Supplies | | Customer Reviews | 4.6 out of 5 stars 227 Reviews | ## Images ![MAQIHAN Borax 7.4 oz Borax Flux for Melting Gold Silver Bulk for Jewelry Casting Kit Hand Casting Jewelry Making Supplies Metal Melting Kit - Image 1](https://m.media-amazon.com/images/I/71boDeZ9vgL.jpg) ## Questions & Answers **Q: Which metals is this borax flux compatible with?** A: This borax flux works perfectly for gold, silver, precious and non-precious metals.
