Sorry if I mssed this somewhere in which case point me to the thread, but firstly, has anyone mixed cerium and tin oxide in the same tumble and if so what happened, secondly any ides as to why a batch of amythest that I am polishing in cerium is doing odd things. It has been polishing for two weeks, some stones are glassy shiny, look dry the same as when wet, but some stones are still shiny but frosty. generally it is the smaller stones that have finished better, is it something to do with the movement of the stone in the tumbler, do smaller stones "travel" further in that they can fall beteewn the larger stones and hence get worked on more?
