A base glass composition which undergoes phase separation was chosen in the system Na 2 O‐ZnO‐B 2 O 3 ‐SiO 2 . Spontaneous and reheat‐treatment opal glasses were synthesized by addition of different amounts of oxides such as P 2 O 5 and ZrO 2 . To clarify devitrification, visible spectroscopy was performed for all samples. Reheat‐treated samples showed Tyndall effect in low temperatures, while they were completely opacified after soaking in 800°C for 3 h. P 2 O 5 ‐or ZrO 2 ‐containing samples opacified spontaneously. The mechanism of opacification in glasses containing the MgO and ZrO 2 was partial crystallization, while in the mechanism of P 2 O 5 ‐bearing one was liquid–liquid phase separation.
