Vark, Varak or Varakh (Hini:वर्क) (IPA: [vərk]) is a foil of pure elemental silver that is used for garnishing Indian sweets. The silver is edible, though tasteless. Large quantities of ingested elemental silver can cause argyria, but the use of vark is not considered harmful to the body, since the quantities involved in normal use are minuscule.
