[QUOTE="Rema Exploration, post: 542548, member: 12586"] Hi there All you need to do is use normal cooking oil Start a charcoal fire in the ground just make sure no drie grass around because some of the stone may cause some firework. Rap the stone in aluminum foils twice. Put them on top the charcoal when they nice and hot and cover them again with charcoal. Leave them in for 10 minutes. After that remove one out and check. If the stone still wet in oil putting back for a nother 5minutes. Make sure they get even heat ? all the way rounds. Repeat the process for all the material. After that leave them out to cool down. Remember some time you might need to repeat carbonizing process couple time Specially if you end up rubbing to mutch. The trick is how to get a good polish Remember sandstone is poress. You must start with fine granual sandstone. The material has to be stabilised and treated after carbonizing. If you need some advice reply I will try upload 1 piece of our product. It's the best finish product on earth [img]https://www.prospectingaustralia.com/forum/img/member-images/12586/1584343434_2012-09-25_12.30.49.jpg[/img] [/QUOTE]
