http://www.glassmessages.com/index.php/topic,17154.0.htmlMy new hobby is learning to restore glass (for personal use only) and I had a little success removing the shallowest of scratches and scuffs using cerium oxide on some of my own collection, but it was
very laborious and time-consuming. I recently gave diamond lapping paste a whirl, with great (and fast) results. Lapping paste is generally used in the restoration of woodworking tools to sharpen metal blades - but it also works wonders on glass. To get rid of a fairly deep scratch on the side of one of my favourite vases took about 10-15 minutes with medium grit lapping past on a felt bob and left it with a near-perfect shine. Another 10 minutes with fine grade cerium oxide slurry will finish it off. Needless to say, I'm
very chuffed.
Although, be warned, it's quite pricey if you go for the best quality stuff (I've found around £8 - £12 for 2g, depending on the grit) but a little does go a long way. You can get much cheaper on eBay, especially if you buy from Hong Kong, but I don't know what the quality is like.
