CRYSTAL REPAIR CHANDELIER ANTIQUE PRISM

May 8th, 2015 Posted in All Repair Projects, Antique Glass Repair, Chandelier Repair

The  antique crystal  chandelier was in disrepair. One of the crystal spires was broken.   We cast a mold  using one of the old prisms as a pattern . First a rough cast is make of crystal . Then the casting is ground and polish . Then the  brass feral from the old broken prism is attached .
