I did my first smelting of WW today and it was a success. I used all the information I got from you guys here on the Cast Boolits site. I fluxed a few times with candle wax, and that seemed to get it really clean. If I understand correctly, the wrinkly stuff floating on the top in this first pic is the tin from the WW? It went into the muffin tins with the rest of the melt. I accidentally let the temp get up as high as 825 degrees, but then I turned it down a little. I think I had picked out the only zinc wheelweight in the bucket, so I don't think any zinc got into the melt. I didn't see any 'oatmeal' floating on top anyway. I plan to cast my first bullets next weekend. I blackened the muffin tins over a fire, and none of the ingots stuck.
