Testing for purity, Patna, ca.1857
By Shiva Lal

Painting; gouache on mica

This Company Painting (a painting made by an Indian artist for the British in India) is done on mica (talc) and comes from a series of nineteen illustrating processes in the manufacture of opium at the opium factory at Gulzarbagh in Patna, Bihar. According to the artist Ishwari Prasad, his grandfather, Shiva Lal (c.1817-1887), began to make the designs for these paintings in 1857. They were commissioned by Dr D. R. Lyall (the personal assistant in charge of opium-making) for a series of wall paintings in the Gulzarbagh factory. However, Lyall was killed in 1857, during the so-called Indian Mutiny, and the scheme was abandoned.

This picture shows the opium being moulded into balls and put into brass cups.
