Abstract
A glass vial which includes a tubular glass container having a closed bottom end and an open top end is disclosed. The bottom end of the container is painted with a ceramic paint. The vial is then fired so that the paint bonds to the bottom end. A laser beam is then used to etch a data matrix code into the painted bottom end of the container. The bottom end of the container may now be read by a machine in order to perform various tests on the sample contained within the vial.
