Later, pieces of obsidian were ground flat and highly polished to improve their reflective abilities. [15], Pumice can be found all around the globe deriving from continental volcanic occurrences and submarine volcanic occurrences. The elongation of the microvesicles occurs due to ductile elongation in the volcanic conduit or, in the case of pumiceous lavas, during flow. Most pumice contains tubular microvesicles that can impart a silky or fibrous fabric. Small earthquakes occurred at the rate of about 10 per hour during 26-28 February.
