Borax as a flux

[Emerald]

Thanks

So is Borax really that old fashioned? It's what we use in class, but if there is an easier way...

erm well grinding a bit of borax down is hardly the most strenous exercise it is lol, people tend to use the auflux cos it doesent bubble as much but i usually put my borax on heat it till it bubbles and then put my solder on, its cheaper and doesent end up all over the bench when you have forgotten to put the lid back on!
