Anthracite iron combined those experiments and the new hot blast processing. In the United States, where the Lehigh Coal & Navigation Company (LC&N) had begun shipping anthracite to Philadelphia in 1820 because the principles could not obtain sufficient fuels for their iron works at "the 'Falls of the Schuylkill' "—so had built the Lehigh Canal and taken over the works of the haphazard Lehigh Coal Mine Company—by the late 1820s having established works that were running smoothly, after building America's second operating railroad in 1827, they'd great interest in exploiting the great anthracite deposits of Schuylkill County for ironmaking, which mills foundries
Anthracite budgerigar mutation Anthracite budgerigar mutation The Anthracite budgerigar mutation is an extremely rare mutation that occurs in the budgerigar. The mutation, similar to the Violet budgerigar mutation, causes a difference in the coloring of budgerigars. Anthracites have black or very dark gray feathers, possibly with some white depending on the budgerigar in particular. The mutation is believed to have started in Germany, and tends to be local to that area. Currently, most owners wishing to obtain an Anthracite need to import these budgerigars from Germany. The description and genetic behaviour of the Anthracite and English Grey are identical, insofar as this can
