Franz Langer Clock – hand carved gilding circa 1830. This project was to replace the top three carvings the eagles and cherub. The pieces were carved in basswood, primed with a bole, and then the 24k gold leaf was applied by hand using traditional methods.

You can see the process in the pictures, we hand carved an original of the duplicate carvings. Once scanned the CNC system cut the rough blanks in two stages. The first shows the main levels and removes the bulk of the material. The second stage imparts some level of detail, but not enough to be considered completed. The examples were are experiment in pine.

It still requires a hand touch; no matter how much computer controlled cutters advance they will never match the dexterity of the human hand. This is one of those perfect examples of a blending of 18th century and 21st century technology and technique.

Once again sign shops are now the most common venues for an age old skill, gilding. Dana Osterman handled the gilding application. Sheets of gold as thin as a hair are applied to the prepared surface and burnished into an adhesive pre-applied to the target. The net result is an everlasting finish.

Nice work! Was the gold leaf sealed with lacquer or urethane? I see them hung in front of a spray booth..

No sealer – gold is the final layer. Just hanging there to dry.
