A gold rubber is used by bookbinders to remove excess gold leaf from a binding after tooling a design or title. Being slightly sticky, it lifts the excess gold without lifting the tooled gold and prevents loose flakes of gold leaf from contaminating other work in the bindery. Gold rubbers are hard to come by commercially so this video shows how I make one beginning with a crepe rubber which is readily available from bookbinding and art suppliers. Note: it is worth just testing your new gold rubber before using it on important work to ensure it does not mark your leather, for example if the paraffin has not yet been fully absorbed.
