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.

A method of marking a microscope slide, the steps of the method comprising:
- providing a microscope slide having an upper surface, a lower surface, and a marking surface formed of a coating affixed to at least a portion of one of the upper and lower surfaces of the microscope slide;
- and
- etching into the coating a configuration which exposes a corresponding portion of the microscope slide and thereby defines a substantially permanent identifying indicia in the coating of the microscope slide.
