15. “Labors of the Months” (Norwich, England, ca. 1480).(the rubycolour is probablyduetogoldnanoparticles mixed intotheglas.)

16. The Lycurgus Cup (glass; British Museum; 4thCentury A. D.) When illuminated from outside, it appears green. However, when illuminated from within the cup, it glows red. Red color is due to very small amounts of gold powder (about 40 parts per million) in glass.
