ABSTRACT:
A glass article having at least one edge of which at least a portion has been laser melted. The laser melted portion scatters light, thus enabling the glass article to be properly aligned. In some embodiments, the laser melted portion also provides a roughened edge having a coefficient of friction that facilitates handling of the glass article. The laser melted portion is formed by irradiating the peripheral surface with a laser beam to cause localized melting.
