Margot, I asked but I'm afraid the response wasn't very positive. Essentially, to be done properly glass restoration requires professional skills and equipment -and plenty of time, which unfortunately is at a premium during the Repair Café. Particularly as you seem to have several chips on several glasses this would be beyond our comfort zone.Can I suggest you search "crystal glass restoration" as I did. You will find several likely candidates for professional restorers. They include https://bluecrystalglass.co.uk/ Certainly worth a phone call or two, though I fear cost may be a factor depending on how much work to how many glasses!
