When a piece of crystal is cracked, those who enjoy displaying the object may believe that it's a total loss. However, repairing the crystal isn't a laborious task. While the item won't be in perfect condition, the crystal will be restored and the cracks practically unnoticeable.
Remove the glass glue from its packaging. Pierce the top of the glue container with a safety pin.
Apply the glass glue carefully to the spots where the crystal is cracked. The glass glue is very thin and will slowly seep into the cracks and repair the crystal. Let dry for an hour.
Use a cloth to shine the crystal.
