This is my second casting session. First session had a little bit of what you see in the picture, but this time it looked really bad. I was using a lee pro 20# bottom pour, lee 2 cavity molds, and bullplate sprue lube. I was fluxing with sawdust and using a paint stick to stir the lead. The lead was bought off a reputable member and the ignots looked clean. I was using 1-2% pewter with this lead. (cowws) I was thinking I need to drain and clean my pot, but am not sure. The pot was new when I got it, so this was only its second session. Any suggestions? Thanks in advance.
