"A heat may be obtained sufficiently great to diddipate Platina, being equal to 44,000 of Farenheit's Thermometer, the combustion of cast iron, copper, iroon wire, or the melting of silver, copper &c. -- Several of these experiments will be shewn with the formation of water, and the explosion of these gases with electricity, &c. The world is indebted to the ingenious Mr. Joseph Cloud, of the mint, for this very simple and beautiful Instrument."
Notes:
Joseph Cloud (1770-1845) was the chief assayer at the U.S. Mint at Philadelphia from 1797 to 1836. His device was an improved oxy-hydrogen blowpipe, which could generate a flame hot enough to melt or fuse metals.
