How to Fix Chips in Crystal Glass

Updated February 21, 2017

Crystal glasses can be an elegant and beautiful addition to any dinner party. Your sparkling, flawless glasses can impress even the wealthiest of guests. However, your glasses won't be very impressive if one of your guests finds a chip--or worse, cuts a lip on a dinner glass. If you find a chip on one of your glasses, don't throw it away just yet. You may be able to fix the chip, or at least round it out so no one can get cut on it.

Buy a diamond file. These can usually be found for about £26 at home improvement stores, or online at websites such as Amazon or eBay. Diamond files can fix chips because diamond is harder than crystal. The files have two sides to them, one flat and one curved, that can handle the various angles of the crystal. There is also a thin handle attached to the file .

Locate the chip on your crystal glass. Be very careful. If you run your fingers across it, you could end up with a nasty cut. Instead, visually inspect the glass to find the chip.

Hold your diamond file with your dominant hand, much like you would hold a toothbrush. Hold the crystal glass with your other hand. Be sure you have a good grip on both, preferably while sitting down to increase your stability. This process takes a combination of strength and precision.

Move the file back and forth across the chip in your crystal glass. You need to push hard enough to file down the chip, but not so hard that the glass shatters in your hand. Use the flat edge of the file on the crystal, except if you are fixing a dip in the glass, which will required the curved edge of the file.

Continue filing until the entire chip has been worn down. This will dull the crystal so that the chip can no longer cut your skin. Large chips can be filed down enough to make the glass safe to drink from. Smaller chips can be fixed and rendered barely noticeable.


Wear gloves with excellent grip while filing the crystal to make sure your hands are safe if it shatters.
