Some dikes of alkali olivine basaltic dolerite from the Egersund area contain glass as a border zone. This glass was heated partly dry, partly under controlled water pressure. The dry heating was made in nichrome or platinum furnaces, the heating under water pressure was made neither in cold seal bombs or in a bilaterally heated hydrothermal bomb. Similar experiments have been made by H. S. Yoder jr. and C. E. Tilley (1956) .
