What is the difference between gesso and composition ornament?

Gesso is a liquid plaster mixture brushed onto the wood base to receive hand-carving or smooth preparation layers. Composition, often called compa, is a pliable paste pressed into moulds and applied to the frame for repetitive decorative motifs. Finer pieces rely more heavily on hand-carved gesso work rather than moulded composition.

Can antique mirror glass be replaced?

Original mirror glass often shows foxing, distortion, and dark spots acquired over centuries of use. While replacement is possible, collectors generally prefer retaining the original plate for authenticity. The aged imperfections contribute significantly to the visual character and historic value of the piece.

How do I identify a Rococo Revival frame?

Rococo Revival frames feature asymmetrical scrollwork, C-scrolls, and organic motifs such as shells and foliage. Popularised during the nineteenth century, these designs emulate eighteenth-century French Louis XV aesthetics with exaggerated curves. The carving is typically deep and energetic, creating a strong sense of movement around the glass plate.
