Antimony ingots question

[19Rams]

I've been blessed with a nice stash of lead, WW, linotype, and tin that I inherited from my dad. On occasion, I would grab an ingot out of the tin box and it would not melt in the pot...just float on the top. I realized those ingots were probably coming out of a small can that was in the box I had designated as all tin. Further investigation showed a tape label identifying those ingots as pure antimony in Dads writing. Question that rises is what to do with that? I'm guessing that heating my propane turkey fryer up to very high and make some #2 alloy with proper weighed ingredients would be the thing to do. Has anybody in the knowledgable world messed with pure antimony?

Did you do a search? Haven’t done it myself, but there are lots of threads describing use of antimony metal to make alloy. Most describe dissolving the metal into the melt, using small pieces kept under the surface. The temps used are around the range typically used for molten lead casting since melting the Sb metal directly at 1167°F to get it into the lead is no more necessary than melting table salt at 1473° to make brine. Pre weighing the lead and antimony metals allows making a precise composition, provided dissolution is complete.

I bought some of Rotometals "super hard" alloy a while back, and attempted to melt it into small ingots. My Lyman pot wouldn't do it, just made "mush"! I finally decided to break it into smaller pieces, I used my hydraulic press and a splitting maul, it shatters easily after a little pressure. My friend said he was able to break it with a hammer.
Added a small amount to a pot of WW it made some nice hard bullets for 357 Sig and 44 Mag

I did that: melted the big ingots into much smaller bars. I used a high btu jet burner and a 12” cast iron pot with a lid. Maybe more heat production and retention than your set up, as I didn’t have any mush to deal with.
