A domed mop brush made from squirrel hair or pony hair, this is used to gently brush over the Gold Leaf once applied to the surface you are gilding. This brushes the leaf into place and brushes away any excess leaf. The Standard Mops have a metal ferrule and the Professional Mops have a plastic quill ferrule bound in copper wiring. The mops can also be used for apply water size made from gelatine capsules.
