What is the difference between gesso and carved wood?

Carved wood refers to the structural timber shaped directly by hand tools, whereas gesso is the plaster-like compound built upon the wood to form fine surface details. Many antique frames combine both methods, using carved wooden foundations embellished with moulded gesso ornamentation. Examining the underside or unpainted edges often reveals the transition between the solid base timber and the applied preparation layers.

How should I clean a antique gilt frame?

Dust these surfaces gently using a soft, dry brush or a feather duster without applying moisture or commercial cleaning sprays. Water and chemical solvents can strip the delicate gold leaf and soften the underlying gesso. If stubborn grime accumulates, consult a professional conservator rather than attempting chemical intervention at home. Gentle preventive care preserves the original patina and metallic finish.

Can I replace the mirror plate in an antique frame?

Replacing the glass is possible, but original silvered plates with foxing and minor imperfections contribute significantly to the historic character of the object. Retaining original glass maintains the visual continuity between the frame and its period context. When a replacement is necessary for functional reasons, traditional silvered glass cut to match the exact bevel and thickness preserves the historical presentation.
