Copper was extensively used in India for utensils, jewelery and many other things. But the bowls, jugs, trays, goblets and other items that are on sale in Agra are a class apart.
The copper objects are actually meant for daily use, but what make them markedly different from their counterparts are the engravings done on them. They are then embellished with enamel colours to give added beauty. This is yet again an art that is supposed to have originated in Persia.
If I remember right, there are a few pieces of it collected by my dad.. a miniature set of hookah, jug, matching goblets and tray and also a dancing peacock.
Just check the pictures to see how you like them...
