Platinum is a precious, silvery-grey metal. It is a highly valuable commodity due to it's scarcity and very little of it is mined each year. It is a non-oxidising metal.
Loose genuine platinum leaf sits loosely between thin rouged paper sheets in the booklet. It has to be handled using a gilders tip (brush) and is used to gild onto moulded,carved and embellished areas. Also used for watergilding and glass gilding.
