<p>[QUOTE=&quot;Kentucky, post: 2350164, member: 33176&quot;]Have to get a chuckle from this one.&nbsp; One of the labs I teach asks the students to rank elements they are examining as dull or lustrous.&nbsp; I am often asked just what luster is, and I respond that it means if it is shiny or not.&nbsp; Since we are in a forum with specific definitions for terms, luster to a coin collector obviously means numismatic luster, however we do enjoy beating each other over the heads with the club of definitions.[/QUOTE]</p><p><br /></p>
