Chipped Crystal Glass
We have a chip in the rim of a crystal glass. I have tried emery to smooth
it - but really it needs the whole of the rim grinding down by about 2 mm. Should this be possible? Will it be satisfactory as it seems tha the rim is moulded rather than cut? Any advice on sourcing a repair if advised? |

I saw someone cut a glass jam jar by immersing most of it in water to damp out vibrations that would otherwise cause it to shatter. |

Any advice on sourcing a repair if advised? Not fixable IMO. |

You could grind it, but I'd do it by hand: get a flat sheet of glass, use some fairly coarse carborundum grit (say -80s or -120s) scattered fairly generously on the glass, wet it to make a paste, invert the crystal whatever-it-is and grind away using a circular motion. It'll be slow; you'll probably need to change the grit to finer grades as you get down to below the edge of the chip, and the ground surface will always be matt, never the original flame-polished edge it was. Wot e said, only I'd use wet-or-dry paper, on a sheet of glass, lots of water. Start coarse, maybe 120? Low pressure, too. Thomas Prufer |

When I tried to cut glass goods on an abrasive disc tile cutter they always shattered. I presume the abrasive was too coarse. I was certainly being gentle. NT |

No the inside is often at a different tension which is why one chip leads
to more and more. Horrible stuff if damaged. If it was part of a set, if you know the company they might be able to sell you a replacement.

Ah - I suspect "Flame Polished" is a description of the rim. |

When I was at university, we had a bloke in the basement who made all the special glass apparatus, discharge lamps, etc required for the physics experiments. Every few years, he did a public demo showing how different things were made, and that was something not to be missed - he was amazing. I got to make a small discharge tube in the glass workshop. Apparently, a few members of staff regularly brought in wine glasses to have chips taken out. He did it, but commented on the poor quality of the glasses and that if they were good quality, they wouldn't chip so easily. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Chris Hogg wrote in : https://tinyurl.com/yc4nkcrv Thanks - beyond me! I have seen it done in a glass factory, making fancy drinking glasses amongst mass produced items like milk bottles, beer bottles and cheap molded drinking glasses. For the fancy hand made ones, they had them on an automatic process, a powered revolving table and a small gas flame would come in for just a few seconds on the rotating rim. The cooling glasses would then move along on a conveyor. In my teens I would cut, bend join and carry out the above process on glass tube for chemistry experiments. It was quite a satisfying process, I remember. If it is chipped, you probably have nothing to loose in trying, or take it to a neon sign maker, to see if they could do it. |
