Borax Flux Cone for Soldering
- Make your own flux for both precious and non-precious soldering with this borax cone
- The borax dissolves to form your own flux paste by grinding down the bottom of the cone in circular motions against a borax dish (sold separately here) with a little water
- After use, the cone will dry out to be used over and over again
- The flux created will help keep the joint clean when being soldered
- A great tool for both professional jewellers and beginners too
