anthracites

Many a time, instead of enjoying the company of lads of my own age, I had preferred dusting these graphites, anthracites, coals, lignites, and peats!

Each ball was of precious stone; one an amethyst, another an African carbuncle, the third an opal, and the fourth an anthracites.

The Willson Bank and Massillon and also Briar Hill grades of coal are principally handled by this firm, who are also operators largely in the Pennsylvania anthracites.

As the variation in character of bituminous coals is much greater than in the anthracites, any rules set down for their handling must be the more general.

Steam, Its Generation and Use

Fire damp and choke-damp, common names for the gases mentioned above, are produced in large quantities in the mines where Tertiary or Cretaceous lignites, or Carboniferous coals or anthracites are mined.

Scientific American Supplement, No. 362, December 9, 1882 Various

A comparatively light draft is best with the free burning bituminous coals and the amount to use increases as the percentage of volatile matter diminishes and the fixed carbon increases, being highest for the small sizes of anthracites.

Steam, Its Generation and Use

It kindles quite readily and burns more freely than the true anthracites.

Steam, Its Generation and Use

However, some bituminous coals have a higher calorific power than some anthracites, because a large part of their volatile matter is combustible and yields more heat than the corresponding weight of fixed carbon in the anthracite.

Many of these woods have become true anthracites, but others again, like those you see before you, have only undergone one phase of fossil transformation.
