Borax Flux Cone


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.
