Product Details This is the fine powder form of Borax used for all precious metals, silver, gold as well as copper. Jeweller’s and Silversmith’s soldering flux: Prevents oxidisation of the solder and soldering area. The powder should be mixed to a smooth paste with tap water to form a toothpaste consistency and applied to the clean and de-greased solder joint. Apply on soldering joins where necessary using fine borax brush Coating for crucibles prior to metal melting: New crucibles need to be glazed with borax before melting your metal which ensures the molten metal flows freely. Sprinkle the borax in the crucible and apply heat with your torch or kiln. Continue to add small quantities until the whole interior is glazed. During the melting process a little borax sprinkled on the molten metal will help to maintain flow and prevent oxidisation. Helpful Tutorials & Guides Health & Safety Data Sheet – Download Here
