It is demonstrated that the color and transmittance of carbon‐sulfur amber glasses are affected reversibly by heat‐treatment. If a specimen is soaked at a given temperature between 1150° and 950°F. for a sufficient period and air‐quenched, the transmittance is characteristic of that temperature. If the same specimen is then soaked at a lower temperature, the transmittance decreases to a value characteristic of the lower temperature. The soaking time required to establish an equilibrium condition as evidenced by attainment of the characteristic transmittance increases from less than 10 minutes at 1100°F. to more than 15 days at 950°F. A change in transmittance at 650 mμ from 54 to 27% was attained in one sample.
