Abstract
A microscope slide having a glass plate, a marking surface coating on an area of the glass plate, and indicia formed by etching away portions of the marking surface coating. The marking surface coating may comprise an epoxy resin material, a ceramic material, or any other substance capable of being affixed as a layer onto a glass surface. The indicia may include machine-readable indicia, human-readable indicia, or both machine-readable and human-readable indicia. In order to produce accurate, high-quality indicia, a laser directed by a computer controller may be used to etch away the portions of the marking surface coating.
