I bought this Mini Mite muller a week or so back. On Friday I took a trip around the bottom of Lake Michigan to pick it up in north Chicagoland. Cleaned up a bit of old dried petrobond, and some staining. Made up a quick batch of green sand today, seems like it worked pretty well. The sand feels very good to me. I got a pretty good deal on the muller. And when I picked it up, the seller kept giving me other stuff ... to the point I was feeling guilty, LOL. I took 3 pairs of tongs (one with 3' handles), 2 small flasks (one steel, one aluminum), small ingot tray, and a new #8 graphite crucible.
