Maybe someone here will know? I have a bunch of glass bottles and stuff. What I want to do is hammer it all into little pieces then "tumble" it to get rid of the sharp edges. If it all works well I may use it in a walkway. But I'm thinking there is some way to do this right? All I've found is this: http://en.wikipedia.org/wiki/Tumble_polishing Anyone have any better ideas?
