Abstract

Glass articles with coatings are disclosed herein. According to embodiments, a glass article may include a glass body comprising glass and having a first surface and a second surface opposite the first surface, wherein the first surface is an exterior surface of the glass body. A coating disposed on at least a portion of the exterior surface of the glass body. The coated glass article may have an effective throughput rate greater than or equal to 1.10×R T , wherein R T is the effective throughput rate of an uncoated glass article in units of parts per minute (ppm).
