Has anyone here tried making damascus without flux, yet? If not, are you considering it? In case you don't keep up with the trends, a growing number of makers are turning to fluxless welding. No more Borax, no more drippy mess, no more relining the forge. In simplistic terms, fluxless welding substitutes the borax for a longer, hotter soak in an oxygen poor environment so almost no oxides form. Basically that means getting your forge up to a high temp (approximately 1260C or 2300F) then reducing the air flow when you put the billet in, so all the available oxygen is burned up.
