Diorama of a laboratory interior depicting the discovery of nickel by Axel Frederik Cronstedt in 1751. This diorama illustrates the type of laboratory in which metallurigical chemists worked in the middle of the 18th century. Cronstedt pioneered the use of the mouth blowpipe for the analysis of minerals. The furnace on the right shows the use of bellows which were used for urging a draught in a fire so it would burn brighter.
