Abstract

This research aims to investigate the effects of heat treatment on color and clarity of ruby. The ruby were heated at 1200, 1300, 1400, 1500 and 1600ฐC in oxygen atmosphere for 40 hours, respectively. Each ruby before heated and after heated, the color measurement by spectrophotometer, to observe color changing and clarity. Found that, the samples had beautiful red and clarity more than before heated. So that, heat treatment of ruby at high temperature in oxygen atmosphere, could to increment valuated of natural ruby. ฉ (2013) Trans Tech Publications, Switzerland.
