Restoration Examples:

In early 2007, we were given the task to restore this historic von Stuck frame. The gesso had weakened in many sections, creating significant loss to the original 1893 gilding. We stabilized the gesso overall and re-gilt (24K), burnished and patinated the repair areas to match the existing coloration.
