How do I date an antique frame?

Dating relies on the construction techniques, corner joints, moulding profiles, and materials such as gesso and giltwood used by period framers. Changes in decorative motifs across centuries also help align the frame style with the period of the artwork it encloses.

How should I clean antique glass?

Antique glass requires gentle cleaning with a soft cloth slightly dampened with a mild, non-ammonia cleaner applied to the cloth rather than the glass. Care must be taken to prevent moisture from seeping under the rebate and touching the paper, canvas, or pigment.
