The work was commissioned by the government and Hellot acknowledges the technical assistance of ‘le sieur Koenig, Ingénieur des Mines’ who had worked in France for ten or twelve years. Hellot (1685–1766) was admitted to the French academy of sciences in 1735 as a chemist. He then travelled in England and was elected to the Royal Society in 1740. The massive series of finely engraved plates showing furnaces and foundries provide details of smelting and metallurgical operations.
