Decided to melt a 5 gallon bucket of CWW I have had for a while and noticed my angle iron molds had oil on them. I figured the oil would burn off rather quickly at 650 degrees but after a partial bucket I noticed the molds still had oil on them and the ingots were oily. Went back to the box where the molds were stored and found a quart of synthetic gear oil had partially leaked onto them. I guess this is a testament to the synthetic stuff holding together at high temps. Had to break out my acetylene wrench and give the molds a good going over to get rid of the oil residue and hit the ingots with brake cleaner which pretty much cleaned them up. Ran the rest of the bucket with no problems and only had 3 zinc weights mixed in with them. Now I have to melt the SWW's which is gonna be fun, with all that stickum stuff they have on them. Will move my lead pot to a place to where I can get up wind of it. I might wait a while to do those.
