Oxynitride glasses begin to oxidize in air when they are heated above 800°C. The oxidation starts with bubble formation on the surface. Continued oxidation leads to a white oxide layer on the surface. Magnesia‐ and lithia‐containing glasses formed crystalline layers, whereas soda‐ and baria‐containing glasses formed bubbly glass layers. The lithia‐, beryllia‐, and magnesia‐containing glasses have good oxidation resistance
