Borax Flux Cone

£8.75

This cone can be used to make a flux used during the soldering of gold or silver. This is done by rubbing the wide end of the cone in a flat bottomed dish with a little water.

The cone will dry out afterwards and can be used repeatedly.

We also sell ceramic dishes to use with borax flux cones.

Please read the safety information prior to purchase and use:
