G'day folks, I need a slice of Taza suitable to cut a 20mm - 25mm diameter disc from but would also need to be around 3-5mm thick. It does not have to be etched because it will need to be redone again anyway. If anyone has anything like this could you please contact me off-list. Thanks, Jeff Kuyken I.M.C.A. #3085 www.meteorites.com.au
