to have experiments made at the Dormsjö blast furnace with this new
refining process, and for this purpose a little Bessemer furnace was
erected there, for which Bessemer had furnished the drawings.
Bessemer Furnace at Edsken, 1858.
These first experiments at Dormsjö were made in the beginning of
1857, under the guidance of a Swedish engineer, John Leffler. The
Bessemer furnace was of a cylindrical form, with flat ends and hung
on two trunnions, placed at the upper edge of the ends. One of these
trunnions was hollow and formed a part of the blast pipe, which
