I saw a posting that stated that they had Linotype biscuts, dross'd but not fluxed.
I have always heard the proper tecniw=que when you melt any alloy for use OR to cast into biscuts you HAVE to flux to get the Tin and Antimony back in solution, then dros which is hopefully just oxides.
If you don't flux, don't you end up with a softer alloy because you remove some of the hardening alloys? Ingots look shiny, but I think not fluxing is bad???
Thanks
