meerschaum. A mineral resembling white clay that is used mostly for making tobacco pipes, meerschaum is German for “sea foam.” About as heavy as water, frothy pieces of it some- times float to shore. Ancients, coming upon it, erroneously thought it was a kind of petrified sea foam, giving it its name. Because meerschaum is absorbent, tobacco pipes made of it become brown with use. In mineralogy it is called “sepiolite.” |
