Got a pair of these 35-40lb chunks given to me along with a pile of keel weights and have no clue what they are. My best guess given the proximity to the ocean they were either bouy weights or counter weights for some tool.
I finally gathered up the courage and dropped one into into the Dutch oven to melt down. It started to melt at around 475deg. Except for the epoxy paint and an odd steel pin it was a really clean melt and was fully melted around 575deg. I filled my available muffin tins and killed the burner. As it cooled I tried to catch when it started to solidify which was somewhere around 450deg if I picked the right time.
I grabbed one of the fresh mini-muffins and brought it in to the house and did a Lee bhn test and it came out to a perfect 14bhn, I’ll check again in a few days to see how much more it hardens.
Based on my initial research did I luck into 2 big hunks of #2 like alloy?
