Silver foil paper is used to decorate South Asian sweets and food. The silver is edible, though flavorless. The silver foil is called Vark, and is made by pounding silver into sheets less than one micrometre thick, typically 0.2 μm-0.8 μm1. Edible silver foil is also made by pounding non-ionic bioactive pieces of silver into paper-thin sheets. The silver sheets are placed between pages of booklets, and the exact materials used in these booklets differ2.
