Compound Blowpipe (replica)

Robert Hare (1781–1858) was a Philadelphia chemist who, in 1801, introduced a blowpipe that produced a particularly steady and intense heat. The compound blowpipe that he introduced a dozen years later used jets of oxygen and of hydrogen to produce an even more intense heat. This replica of that instrument was made in anticipation of the opening of the National Museum of History and Technology in 1964.
