Very interesting, Dan.

Can you make sandpaper with that ground glass?
WOW !! great idea !!
But you need to figure out the right size of the grain and glue to the paper with the right type of glue... and make it smooth and even without any clusters...

Another idea: why not try to make some polishing compound? you could mix it to some sort of paste like... toothpaste? and then use it to brush things and make them shiny, mabe even mirror-finish !
