[QUOTE="Lefty, post: 109371, member: 2976"] Cheers all. Yes, it poses it's own challenges. Everything I cabbed before this was agate or petrified wood which were as hard as the hobbs of hell and so was at the opposite end of the cabbing spectrum to to this stuff. You really have to be gentle with it - in addition to being prone to parting on the saw and chipping if too coarse a grinding wheel is used, it grinds away very quickly and you have to be very careful not to overgrind. You can take it off but you can't put it back on :o I don't know of any sorry AtomRat but I think the stuff is found on top of most significant copper ore seams so I would think the chances are good. Exactly how toxic the stuff is I'm not sure. Certainly, absorbing it by ingesting or inhaling dusts or mists must be very bad for you. We used to use copper sulphate as a fungicide when I worked on an organic smallcrops farm. [/QUOTE]
