Shell Gold gets its name historically as it used to be stored in shallow shells such as clamshells. Shell gold is made from mixing genuine gold powder, palladium powder or silver powder with gum arabic into a tablet form. It is applied by using a slightly damp brush and gently agitating the gold pan. Shell Gold can be used for calligraphy work or for touching up areas such as intricate frames where Gold Leaf will not get into.
