The construction and operation of a micro-cone-softening apparatus [electronic resource] / A. Jongejan, Mineral Sciences Division. Ottawa : Queen's Printer, 1967. iv, 33 p. : ill. Technical bulletin ; TB 89 Cover title. "June 1967." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “The construction and operation of an apparatus with which cone-softening temperatures can be determined are described. The temperature of the furnace, which contains the cone, is controlled and can be recorded. The silhouette of the cone can be photographed with a standard grid as background, so that its extent of deformation can be determined quantitatively. The apparatus is built from components that can also be used in other combinations for other purposes"--Synopsis, p. i.
