[QUOTE="Bushbear, post: 305982, member: 9334"] Hi shivan. Whilst I have never had anything to do with this type of opal during my last cutting course the instructor touched on this method. My understanding is the sugar /acid treatment is instead of polishing as it leaves the matrix with a clear gloss finish. The liquid glass is a two pack that is applied to a stone to fill in any imperfections and as before it cannot be polished after application. But the results are supposed to be quite good. [/QUOTE]
