Silver still won’t melt!

What pressure is your regulator at, and any chance you could upload a video to Youtube?

Im not familiar with this torch but can you adjust the nozzle on the torch to get more air into it ? the slots at the bottom of the nozzle. this will make it burn hotter

Nah, the Sieverts entrain air according to the gas flow, no other adjustment. A 3941 is the standard nozzle and is plenty to melt reasonable quantities of metal with enough propane driving it, but a hearth also helps.

A few issues I know of that can occur … Sievert tortures run on propane and not butane … mostly running with a hose failure valve and not a small regulator … a jet inside the burner controls the gas flow and can sometimes get partly blocked or corroded.

A common mistake I’ve seen is using a crucible too large for the torch. A 2” Square Crucible/Scorifier is plenty big enough for most jobs and can hold 20-30g of silver. Larger crucibles are much harder to heat properly and mostly need oxygen mixed torches. I have a large variety of nozzles for my Sievert torch and before getting an Oxy/propane set up my go to nozzle for this small size crucible was the 2941 burner I also had to include creating a small reflective ceramic cave surrounding the crucible.

One last suggestion if all else fails, I used to sometimes use pieces of barbecue charcoal placed on top of the crucible and silver. It all ignites and starts to glow radiating heat down towards the silver creating a mass of radiant heat on top of the crucible. When ready to pour it can be flicked off or simply held back as the silver will flow from beneath the charcoal embers … good luck with it … Nick
