Hey all, got a quick question. I’ve been using my Dutch oven over a Turkey fryer to melt a bunch of scrap lead. Most of the lead is scrap Linotype that was taken from a printshop. Most of it has been melts or scrap from remelts but some has been Linotype letters or slug bars. I’m ladle pouring from a cast iron ladle into RCBS and Ohuas ingot molds. I have 5 molds I’m using. 3/4 of a ladle pours one ingot and pour one at a time. I’ve noticed on many of my ingots I’m finding a slight cavity in the side of the ingot. Sometimes more than others. Some none at all. It’s not siecifuc to a mold and just happens randomly. I’ve tried to speed up and slow down my pours and haven’t seen much of a difference. I’d say out of the 20 ingots I pour at a time, 30-50% of them have a variation of this cavity. I let the molds cool after pouring for about 10-15 minutes before dropping them out. What am I doing wrong??
