A method of making a transparent article includes mixing an oxygen source, a nitrogen source, a magnesium source, a silicon source and a calcium source. The oxygen source, the nitrogen source, the magnesium source, the silicon source, and the calcium source are milled and heated to form a molten oxynitride glass modified by calcium and magnesium. The molten oxynitride glass modified by calcium and magnesium is then cooled to form a transparent body having ballistic resistance with a level of performance satisfying Level IV of National Institute of Justice Standard 0108.01. Transparent articles having transparent bodies formed from the oxynitride glass are also described.
