Identifying Aluminium Foil on Sweets
Adulteration in silver foil can be easily identified by gently wiping the top layer of the sweet. If the silver residue sticks to your hand, it is definitely aluminium. Also the quality can be checked by burning the material, genuine silver foil burns away completely leaving glistening white spherical ball of the same mass while aluminium foil is reduced to ashes of black grey colour.
