There was a violent effervescence at the upper surface : at the lower or negative surface, there was no liberation of elastic fluid; but small globules, having a high metallic lustre, and being precisely similar, in visible characters to quicksilver, appeared ; some of which burnt with explosion, and bright flame, as soon as they were formed, and others remained, and were merely tarnished, and finally...

By this process the steel becomes more highly carbonized in proportion to the quantity of flux, and in consequence is more brittle and fusible than before....
