Copper Leaf is only recommended for interior use and will need sealing as it will verdigris and eventually go green. There are two grades of Copper Leaf, a standard grade and an Italian grade which is of a slightly better quality. Imitation Silver Leaf is available in booklets of Loose Leaf and Transfer Leaf, each leaf measuring 140mm x 140mm. Loose Leaf is where the leaves are placed between the pages of the booklet and Transfer Leaf is where the leaves are adhered to a piece of waxed tissue between the pages of the booklet. It is also available in bundles of 100, 500, 1000 or 5000 sheets of loose leaves, each measuring 160mm x 160mm. The gilding process is the same of when using Genuine Gold Leaf, a gilding size is thinly applied to the surface and once a dry tack, like a tack of a post-it note, it is then ready to take the Leaf.
