Some of the fine decorative filigree has been damaged and burned out in this antique slag lamp shade frame. For this repair, it is necessary to create a metal casting. A clay mold is formed usng a section of the good undamaged filigree. The clay mold is cured and hardened then filled with a molten metal alloy. After curing, the new metal casting is trimmed to fit into the empty space then carefully soldered into place. The new metal casting is then given a patina finish to match the rest of the slag lamp shade. |
