Hi Damian, >Does anyone out there have a source of dental stone in Australia? I asked at my local dentist and she directed me to a Dental Mechanic (Denture Maker) 100m up the road. I called in and explained what I wanted it for and he was happy to place an order for a 20kg tub which cost $70(inc. gst). -- Regards Dave http://www4.tpgi.com.au/users/daveg/index.html
