As a plagioclase feldspar, oligoclase is endlessly useful as a tool to teach mineralogy. With a standard hardness of 6 on the Mohs scale, 2 planes of cleavage, and a characteristic nonmetallic luster, feldspar makes for a wonderful example of many mineral physical properties. This 1" sample can be used to great effect in any geology classrooms learning about mineralogy or igneous petrology. It is also a great addition to any identification exercises, especially when paired with an alkali feldspar. Each sample is approximately 1" long and comes in a labeled plastic bag.
