What is French polishing?
French polishing is a wood finishing technique that results in a very high gloss surface. French polishing consists of applying many thin coats of shellac dissolved in alcohol using a rubbing pad lubricated with oil. The rubbing pad is made of absorbent cotton or wool cloth wadding inside a square piece of fabric (usually soft cotton cloth) and is commonly referred to as a fad. "French polish" is a process, not a material. The main material is shellac, although there are several other shellac-based finishes, not all of which class as French polishing.
