Etching

Metallography is both an art and a science, and the artistic aspect comes into full play with etching. The as-polished surface of a metal sample is not unlike a white canvas waiting for the artist to paint a picture on it. Etching can be accomplished by several methods: optical etching, chemical etching, electrolytic etching, cathodic etching, and heattinting.
