I recently bought some roughly 35 pound ingots of 3-4% antimony lead and someone asked how I was going to get it into the casting pot. 3 such ingots fit safely in a standard 5 gal propane cylinder with the top cut off. The burner is a $50 Bayou Classic 50K BTU. I tried tipping it before I fired it and it was solid. I still need a windscreen around the pot. After the alloy was melted I stirred in 1.1 pounds of Tin, for the 110 lbs of Alloy, with a wood stick. I used a stainless ladle to pour 4+ pound ingots. Oh and guess what makes a nice lid for a propane tank pot between sessions.
The Rotometals Alloy was really clean.
