French Polishing: Technique, History and Care

French polishing is a method of applying many thin shellac layers with a rubbing pad, producing clarity and depth rather than a single heavy film. It became closely associated with fine nineteenth-century furniture.

What to look for

A high gloss is not proof of an original French-polished surface. Period finishes may have been renewed, partially stripped or polished differently over generations.

Common mistakes

Routine refinishing can erase patina, tool evidence and historic coatings. Silicone furniture products also complicate later conservation.

Care and repair

Clean gently and protect from heat, alcohol and water. Where renewal is justified, match sheen and colour to the object rather than imposing a showroom gloss.
