[QUOTE="rough2cut, post: 227108, member: 3816"] I stopped using Perspex 30 years ago. My Special alloy is a lap I developed that just seems to work. Cant take good photos so I get cutters who I know are good to test my laps and polish, who also have the overseas laps and polish in there kit to test against. I would hate to drop that stone on a glass lap while its rotating. Im on wolfram Id bleed out and probably create a new polish at the same time. Oxides have long past there use by date. Diamond is fast and efficient for most stones and plastics aren't very consistent. Quartz has always been hard to master a good polish and I avoid it as it always takes far too long to achieve a very good finish. I haven't seen your faceting under a halogen light with a 10X lense to see if your results are good. My faceting class is all about reckonising a good polish. That why I always get my laps and polish tested elsewhere for independent verification. Regards Anthony [/QUOTE]
