This is the "tinner's flux" I have been talking of.
Tinner's flux is a mixture of zinc chloride and hydrochloric acid. One can
make this by dropping pieces of zinc metal into muriatic acid (the trade name

will probably tell the tale. The recepie has been around for at least a
century. Muriatic acid is used for cleaning masonry, and can be bought in many
hardware stores.
