Banded coals grade from dull banded ("splint coal") to bright banded, depending on whether dull bands or bright bands are dominant. The bands are divided into four major lithotypes: durain (dull, grainy texture, tough), fusain (dull black, charcoal texture, hands get dirty), clarain (bright, satiny texture, brittle), and vitrain (bright, black, glassy, brittle). 3, record 1, English, - durain

Les charbons sont classés en six lithotypes en fonction de leur aspect macroscopique. On distingue les charbons humiques(lithotypes vitrain, clarain, fusain et durain) qui provienne de débris de plantes macroscopiques [et les] charbons sapropéliques(lithotypes cannel coals-spores et pollens, bogheads-algues). 2, record 1, French, - durain

Le durain est une substance, grise à brun noirâtre, à éclat mat, formant des lits fréquents mais peu abondants de quelques millimètres à plusieurs décimètres d’épaisseur. Il est fait de débris végétaux ayant perdu leur caractère originel. 3, record 1, French, - durain

Coal that absorbs rather than reflects light, containing mostly durain and fusain lithotypes. 2, record 2, English, - dull%20coal
Record number: 2, Textual support number: 1 OBS
An early division was into three types: bright coal, dull coal and mineral charcoal (or mother of coal). Another system [divided coal into] four types: fusain, durain, clarain, and vitrain. This coincided with the classification put forward by ... the United States Bureau of Mines where coal is divided into anthraxylon - bright layers of plant material and attrius - darker debris material. Today coal classification is based on the organic material seen using different optical microscopic techniques. There are three main groups: liptinite (or exinite), vitrinite and inertinite with many further divisions [within these three groups]. 3, record 2, English, - dull%20coal

Le boghead est un charbon dur et terne à très haute teneur en matières volatiles (55 à 60 %), qui brûle en laissant beaucoup de cendres, ce qui le rend impropre au chauffage domestique. Il est imprégné de matières bitumineuses qui peuvent être libérées par chauffage pour donner des hydrocarbures liquides (huiles). 4, record 3, French, - boghead
