Borax Cone

Borax cones are a dry form of flux. Used with water
and a Borax Dish (999 AAI) to form a paste.
The amount of water required is minimal - wet surface of
the dish and tip out excess - what remains is sufficient
Move the cone in a circular motion (whilst applying a
little pressure) in one area of the dish. Due to the
ceramic texture fine deposits of the cone are left in
the water and in turn form a paste. The paste is then
used as a flux to keep the joining area clean while
soldering.
