| Description: | Crude naptha sample from the Pumpherston Oil Company Limited at Mid-Calder, a leading company in the former Scottish oil-shale industry. British Geological Survey Petrology Collection sample number MC 7719. A product of the first distillation process where the crude oil is distilled into crude naptha as well as crude distillate (or 'green' oil) and coke. The first distillation process is facilitated by the use of steam which passes through the oil in each still. This lowers the temperature at which the oil distils and so prevents decomposition of the oil and it causes a certain amount of agitation and so tends to prevent any local overheating in the still which may have led to damage. |
