View Full Version : Propane torch for smelting small batches

This may be a silly question.
Does using a propane torch to melt alloys such as rotometals super hard affect the properties of the alloy? I ask because I am starting to use these metals to adjust the composition of my base alloys and I’d like to make 1/2 pound ingots but I don’t want to get everything all set up just to work on 5 lbs of alloy. I will obvious use proper technique to try to keep the SB mixed in well.

Shouldn't bother it a bit.

I've done it for small batches but just cast my superhard into boolits that I can use as needed. The torch method gets lead awfully hot so you will get a lot of oxide. You also may get lead fumes which isn't good. IIRC roto is now selling superhard as nuggets.
Well, a propane flame produces heat, heat is hot, and hot is the only thing needed to melt lead...[smilie=s:
Not long ago I bought some Linotype "nuggets" from Rotometals and it came in a 5 lb. bag. Nuggets are good for mixing alloys...

Thanks guys. I’m going to look into the nuggets once I’m done with the bars I have.

I don't think that would hold true. The lead runs off of whatever you are melting as it reaches the melting point.

A propane torch and a small pot should work well enough.

A Turkey fryer is just a Propane torch with the flame turned low. Get a good thermometer and you wont have any problems.

I have an old cheese wheel size weight that is 1-1/2”x 14”. I clamp it in the vise and position a torch to where the melted alloy drips into my Lee pot; just have to watch it closely. Carefully done- nothing to it.
