Repairing Glassware Scratches
Everyone will come across this issue and some point or another. A favoured piece of glassware has been dropped or just mishandled and has picked up some ugly marks and scratches. Most people just chuck the offending item away, or hide it in a dark corner, even though it can be repaired with not much effort at all. With the right knowledge and materials, you can get your glass looking spotless again.
1.) Trying to rub the scratch out using harsh abrasives will not work. This may work on wood, but on your favorite whisky glass, youll end up with a horrible opaque patch that will look even worse and be even more difficult to remove. Cerium oxide is the very fine abrasive that professionals as this is much kinder to the glass. You should be able to find this at glassware shops or jewelers.
2.) You now need to get a polishing wheel. This is form of spin buffer that has a soft pad and is fitted onto a hand drill. When abrasive is added to the pad and it spins up against the glass surface, it buffs any marks away. It is very important that the polishing wheel is clean and free from any grit. The drill should not be used on a high setting as the pressure on the glass may be too large. Crystal glass is stronger and so can withstand higher spin speeds.
3.) If the scratch is quite large or deep, you may find that a polishing wheel is not enough. Special resin is often used for serious scratches and this can be found at most hardware stores or glassware specialists. Youll need to ensure that the resin you use has the same refractive index as the glass, otherwise it will stand out like a sore thumb, especially on crystal vases and glassware. Once you have filled the scratch, you can then use the fine abrasive and polishing wheel to smooth the glass off.
