[TheForge] Re: New Discoveries: Ersatz EZ Weld

[David E. Smucker]

Some smiths around here use a flux that is a mixture of boric acid (roach 
kill) and iron oxide.  They get the iron oxide from the pottery suppliers. 
I don't understand the chemistry of what is happening at the melt 
temperatures.  This flux seems to work very well for them.
