Amorphous


Definition:

  • (a.) Having no determinate form; of irregular; shapeless.
  • (a.) Without crystallization in the ultimate texture of a solid substance; uncrystallized.
  • (a.) Of no particular kind or character; anomalous.

Lampblack


Definition:

  • (n.) The fine impalpable soot obtained from the smoke of carbonaceous substances which have been only partly burnt, as in the flame of a smoking lamp. It consists of finely divided carbon, with sometimes a very small proportion of various impurities. It is used as an ingredient of printers' ink, and various black pigments and cements.
