Silver staining

In pathology, silver staining is the use of silver to selectively alter the appearance of a target in microscopy of histological sections; in temperature gradient gel electrophoresis; and in polyacrylamide gels.

In traditional stained glass, silver stain is a technique to produce yellow to orange or brown shades (or green on a blue glass base), by adding a mixture containing silver compounds (notably silver nitrate), and firing lightly. It was introduced soon after 1300, and is the "stain" in the term "stained glass". Silver compounds are mixed with binding substances, applied to the surface of glass, and then fired in a furnace or kiln.
