Microcline Feldspar – Pack of 10
by American Educational Products

Microcline is an igneous rock that is rich in potassium, and contains minor amounts of sodium. It can commonly be found within both granite, and pegmatite. It is typically found as white, clear, pale yellow, brick red, or green in color, though this variety appears pink due to the red and white color mixture.

Each rock or mineral specimen measures approximately 1-2 inches in length along its longest side.
