Anthracite iron as an ingredient into a reverberatory furnace (and in later years, a Bessemer converter). Anthracite, also known as stone coal or rock coal, is very difficult to ignite, mine, clean, and break into smaller chunks and requires correct conditions to build heat or hold temperature and sustain burning—which oft depend upon the size and uniformity of the coal particles. Yet American cities were cramped for fuels, woodlands were exhausted near bigger towns and Philadelphia, largest city in America needed fuels for mills and foundries as well to sustain manufacturing.

Anthracite budgerigar mutation just one Anthracite allele correspond to the splits of recessive mutations. A single Anthracite factor has a similar effect to the Dark mutation, causing a Skyblue to become Cobalt in appearance - as was suspected with the English Grey. In fact, the similarity of the Anthracite to the English Grey is striking. The description is virtually identical, and the cobalt appearance of a Skyblue with a single Anthracite factor is exactly what was suspected for the English Grey. The interaction of the Anthracite and Dark budgerigar mutations has not yet been investigated. It is expected that a combination of the
