ABSTRACT:
A microscope slide having on a first side an opaque, scratchable coating located at a marking region of the slide, and on a second opposing side located generally behind the scratchable coating at the marking region, a contrastingly-colored coating. Upon scribing an identification mark into the scratchable coating and thus removing the scratchable coating where scribed, the contrastingly-colored coating on the second side of the slide becomes visible from the first side of the slide in the area scribed.
