摘要

A method of making a glass container with an optically readable graphic data carrier. A glass container is exposed to electromagnetic radiation to produce discoloration within the glass of the container, and then focused beam energy is directed at the glass container in a pattern corresponding to a desired graphic data carrier to heat the glass and selectively remove the discoloration in the pattern corresponding to the desired graphic data carrier.
