Filigree Repair Slag Lamp Shade

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.
