The striae pattern can be observed in radiated optical quartz with eyes, which can be observed only using striae-checking apparatus before. Contrasting striae observed in polarized light and striae pattern appeared by radiation, we can conclude that striae appear color because of radiation. Crystal lattice distortion brings about stress, and form striae under visible light. Analyzing composition by ICP instrument, higher impurity content Al3+ can be detected in striae area contrast to striae-free area.
