Frederic de Blewston
From Graces Guide
1675 Frederick de Blewstone from Germany constructed an experimental furnace in Wednesbury, in an attempt to smelt iron using coal, traditional charcoal being in short supply. Unfortunately the attempt failed because of contamination from the sulphurous gasses emitted by the coal.
Dr. Frederic de Blewston obtained a patent from Charles II. on the 25th October, 1677, for "a new and effectual way of melting down, forging, extracting, and reducing of iron and all metals and minerals with pit-coal and sea-coal, as well and effectually as ever hath yet been done by charcoal, and with much less charge;"
