Bronze was commonly used to cast containers such as cups, urns, and vases. People also shaped bronze into weapons and armor such as battle-axes, helmets, knives, swords and shields. Bronze casting in Bhutan was introduced only in the 17th century and was mainly spread through the visiting Newari artisans that came from Nepal. The Newars were first invited by Zhabdrung Nawang Namgyal to cast bronze statues and religious items such as bells and water offering bowls. It was through these artisans that the art was introduced and today, quite a few Bhutanese practice bronze casting.
