Non-Fiction: Rock and Gem magazine, Nov 2008 edition.
Feature article on rock tumbling. Something went horribly wrong with the most recent batch. I think maybe I only put in 1 or 2 TBL of cerium oxide instead of 3, and it wasn't enough to make a nice glassy surface.
Next weekend when the new batch finishes this first rough tumble, I think the botched batch will go back in for another week with the cerium oxide. Also maybe some plastic pellets for rubbing up against? I've got them but have never used them.
