Hey Dave,
When Bob was working as a full time restoration Smith he said he would make
about 100 forge welds per day.
I don't know where he got the info about  anti-caking ingredients in the
20MT Borax, but I know from personal experience, that the Anhydrous borax is
superior to it.
When I weld up my damascus billets, I often start out with 40 layers of
several types of steel and nickel alloys, that = 78 simultaneous welds.
The addition of the fluorspar and boric acid definitely gives me a higher
success rate than borax alone ,on these complex welds.
Chuck
