ABSTRACT:
The invention relates to a microscope slide formed from a transparent glass plate on which a first coating (3) and a second coating (4) contrasting therewith are located aligned one above another in a marking region (1b), the second coating (4) being designed for providing a marking (6) by removing the material of the second coating (4). In order to improve the microscope slide, it is proposed that the two coatings are located on one side (2) of the glass plate (1), the second coating (4) lying over the first coating (3), and wherein at least the surface of the first coating (3) is designed by comparison with the provision of the marking (6) on the second coating (4).
