Crystal objects, from figurines to punch bowls, are highly prized for their enduring, multifaceted beauty and practical strength. When a crystal item is broken, cracked or chipped, owners might count it as ruined. It is, however, possible to repair damaged crystal, even at home, and while the result may not be as good as new, the item will be usable once more.
Repair cracks or breaks
Apply the glass glue sparingly and let it dry in the sun if the item is only cracked. Glass glue is ultraviolet sensitive and dries stronger in the sun. The glue is very thin and seeps into the crack for an inconspicuous but strong repair. Do not try to use superglue or other thick adhesives which will be visible and rough to the touch when dry.
Lay the pieces out like a jigsaw puzzle if the item is broken, so that you can quickly place them together with the glue on the edges.
Place the glue on the broken edges according to the directions on the glue package. Carefully stick them together one by one according to the directions on the glue package. It may be useful to have a helper to hold the pieces while you bond the edges.
Polish tiny chips with 600-grit sandpaper. Note: Chips are harder to repair. The process typically involves grinding with felt wheels and pumice, and should be done by a professional glass restorer.
