| Description: | A large specimen of 'Torbanehill mineral' or torbanite. It is a cannel coal very rich in gas constituents. In appearance it is dull and when burnt it makes a chattering noise. For this reason it was sometimes known as 'parrot coal'. This specimen is from the R. Muir and Company pit at Armadale, West Lothian. British Geological Survey Petrology Collection sample number MC 7681. Torbanehill mineral was used as a source of oil. Whereas a rich oil shale would give 60 or 70 gallons of crude oil per ton, Torbanehill mineral or torbanite as it is known today would give a yield of 90 to 130 gallons of crude oil per ton. The Torbanehill or Boghead Cannel Coal was found over a small area in the Armadale district. It was worked from about 1850 to 1862 until the field was exhausted. It has mainly historic interest and when available it was in great demand due to its very high yield. |
