Hey everyone, I can't imagine that this question hasn't been asked before, but I must be using the wrong keywords. I used a small electric crucible (for lead and pewter) to heat up pewter and pour it into a coin shaped plaster mold. Truthfully, I'm pretty pleased with the level of detail, but I've got some 'burned' colored discoloration on the coins. I've tried gently washing with soap and water which got off some of it. 1) am I doing something wrong to produce that coloring? 2) will silver polish clean it up, or will it damage the pewter? (almost certain it will be fine, but thought I'd double check) Should I just be scrubbing harder with soap and water? For whatever reason, the image uploader isn't working. I'll try to get one into the comments after I post this. many thanks!
