Silver solder will not melt ?

[flynnboy]

Try the solder on another item, does the solder melt on it's own eg. on a solder block, did you buy the solder from your usual supplier, are you fluxing the join or just dipping the solder ( you say you are using a powder flux )
is the solder Jewellers grade or industrial type silver solder

Hi, it is the same solder, same flux and same method I have used for years. I put a small cut of the solder wire and flux on a brass plate and it did melt and flow, although it did seem to take a while longer than I would have expected. I cannot recall the exact name of the solder wire but it is Cookson, 1mm and the lowest melting point available, the flux powder is what I have always used - easy flo - Thanks
