Hoping someone can help me out here as I'm becoming very frustrated today.

I'm new to silversmithing and I'm trying to melt down some fine silver grain today... Without success.

I've got a Sievert torch running on propane, and two nozzles ( needlepoint and burner 3939 which is a larger ).

My question is, do I need a much larger nozzle than the 3939 in order to get enough heat? The silver starts to glow red then becomes a tad molten in places but never quite becomes molten.

If this is the case then which nozzle would anyone suggest?

Many thanks, much appreciated.
