Glance

Glance. A number of minerals, chiefly the "sulphides," are designated by the name "glance" - e.g. copper glance, silver glance, cobalt glance, etc. The term is derived directly from the German glanzen, to shine or glitter, and is therefore only applied to certain substances which exhibit a high lustre.
