Hello !
Nice to meet you.
I have found this document on : alt.crafts.blacksmithing newsgroup
"recommended flux for mild steel is clean sand and borax. mixed 4
parts sand and 1 part borax..
Ordinary borax contains water, when this is heated, bubbles and is
cooled it becomes borax glass. Pulverize this and mix 4 parts of this
to 1 part sal ammoniac (ammonium chloride). This mix is good for
carbon steels..
High carbon steel flux is 50% anhydrous borax, 25% boric acid and
25%silica sand.
Where would I get these?? Let your fingers walk.. Call chemical supply
houses.."
Do you confirm this method ?
Many thanks
