Hehe, Sparkafire, some of your replies make me laugh. I was as surprised as you about the glass tip so I checked Google and although there was hardly any info on on it I did find the below link, still sounds bizzare though.
It says....
''Crushed Glass – This type of mulch is not nearly as dangerous as it may sound. Crushed glass has become more popular as container gardeners discover their colors and high aesthetic value. Crushed glass offers superlative drainage and also helps to keep away pesky insects and bugs, as well as offering a more modern look.''
