  8. The experiments show that the color of the iceland spar can be changed when heated to a certain temperature, that is, light yellow iceland spars will fade when heated to 360 - 370, while dark yellow iceland spar will fade at 440 - 450, brownish yellow iceland spar at 460 - 470 ; and the color of light purple iceland spar can be removed when heated to 390 - 400, while the color of deep purple iceland spar can be removed at 440 - 450, deep reddish purple iceland spar at 460 - 470. on base of the u - v absorption spectrum, we find that the u - v absorption spectra of the faded iceland spars are paralleled to the x axis, the transmittance of them are also greatly improved

    實驗表明，冰洲石在加熱到一定溫度時顏色會發生變化：淺黃色、深黃色和褐黃色冰洲石分別在360 - 370 、 440 - 450和460 - 470完全褪色；淺紫色、深紫色和深紫紅色冰洲石分別在370 - 380 、 440 - 450和460 - 470時完全褪色。通過對褪色后冰洲石進行紫外-可見光吸收光譜測試表明：完全褪色后的冰洲石在紫外-可見光的吸收光譜上表現為一條近平行x軸的直線；紫外、可見光區的紫區的光透過率有了很大了提高。
