Two methods that are widely used to enhance the color of gemstones are irradiation and heating, usually in that sequence. Table 36.11 summarizes some of the heat and irradiation treatments that have been used. The reason for treating (processing) gemstones is invariably to enhance their appearance and thus increase their value. We will review the general features of the different treatments and the science behind them, but refer discussion of the details to the sections on particular materials. All irradiated samples will be heated. 

A second series of two articles was published by Toyota Research in the same year, 1993, in the Journal of Polymer Science Part A Polymer Chemistry. The first article [23] was similar in theme to the above work published in Journal of Materials Research. The montmorillonite was intercalated with -caprolactam in an aqueous HCl solution. This orga-nomontmorillonite was treated in the same way as the 12-aminolauric acid-exchanged montmorillonite in the above work by blending it with e-caprolactam and aminocaproic acid and producing the polymer nanocomposite at 160 °C for 6h. The montmorillonite content varied from 1.9% to 7.1%. The Young s modulus and heat distortion temperature of...
