Hi Bill

It is time consuming but if you position your stones in a good
mechanic's vise one by one I think you should be able to crush them,
then again maybe you have to find someone from the railway co. and have
him ride the locomotive over them (G)

Have fun and take care

The only problem is that short of taking it out onto the sidewalk and
hitting it with a sledge hammer the stuff will not break.

Any suggestions?
