Components of an electronic device, such as glass components, are susceptible to surface damage. Glass components can be strengthened by providing ceramic particles at the exposed surface of the glass. Ceramic particles can also provide optical features, such as color, opacity, and haze to enhance the appearance of the resulting composite article. Where ceramic particles are provided at the exposed surface, the ceramic particles can also produce a desired tactile feature.
