A transparent ceramic composite armor is made of a crystalline transparent ceramic material and an amorphous glass phase material. The armor includes a first portion containing 100 per cent ceramic material; a second portion contiguous and integral with the first portion and containing a combination of the ceramic material and the glass phase material; and a third portion contiguous and integral with the second portion and containing 100 per cent glass phase material. Relative volumetric amounts of the ceramic material and the glass phase material in the second portion are inversely related and a greatest volume percentage of the ceramic material is adjacent the first portion. The volume percentage of the ceramic material in the second portion decreases a direction away from the strike face of the armor, while the volume percentage of the glass phase material increases in the same direction.
