Vases, drinking glasses and other collectibles can all be made of lead crystal. Consisting of a marriage between zinc oxide and crystal, lead crystal is what is commonly used in making a variety of objects including glassware for a dinner table. Chips along thin edges such as the rim of a glass can occur even when the utmost of care is practised. Smoothing a chip can often be accomplished with careful work and patience at home.
Put on safety glasses and gloves for protection. Examine the chip in the crystal glass or other item to determine the extent of the damage. Look for signs of cracks that could signal the need for more extensive professional repairs.
Wet a small piece of silicon carbide cloth and wrap it around a small-diameter dowel. Hold the cloth securely so that it is tight around the dowel.
Rub the cloth across the surface of the chip in the crystal. Begin at the thickest point of the crystal and begin smoothing. Work your way up to the thinnest part of the crystal taking care with the amount of pressure being applied.
Wet the silicon carbide cloth as needed. Work the cloth across both sides of the crystal glass or object as needed.
Apply a small amount of toothpaste to a clean soft cloth. Rub the chipped area on the crystal to further smooth and polish the damaged area. Do not use gel toothpaste for the project, and wipe all excess paste from the glass.
