He was able to melt sizeable quantities of platinum with this blowpipe. Later, it was discovered that when such a blowpipe flame acted on a block of calcium oxide, a brilliant white light resulted—limelight. His device was also the ancestor of the modern welding torches. He presented a paper describing his invention on 10 Dec 1801 to the Chemical Society of Philadelphia. |
