Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> In the method of tinning, a layer of molten tin is deposited on metals which are called ‘kalhaee’. A greenish layer is formed on the surface of copper or brass vessel which is poisonous and harmful. If buttermilk or curry is placed in such a vessel it gets spoiled. Tinning is done to prevent all such damages.
