    has anyone in Aussie land been succesful in creating a sand mold to fuse glass.  I tried a combination of washed river sand (purchased from a local landscaping supplier) and bentonite – when I fired it to dry parts of the mold looks as though it burnt?  I’m guessing the sand must have had some kind of particals which didnt like the 700deg Cel.temp.  The percentage of bentonite to sand was about 10% with the water added to be able to grap a handful of mixture for it to stay in a ball.
