In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0• t to about 0.3• t ). In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a point between the first surface and the second surface and increases from the point to the second surface. The concentration of the metal oxide may be about 0.05 mo1% or greater or about 0.5 mo1% or greater throughout the thickness. Methods for forming such glass-based articles are also disclosed.
