Product Overview
One of the most common minerals in the earth's crust, feldspar has a variety of physical properties that make it a quintessential mineral to study. It distinctly shows two planes of cleavage & is part of Bowen's reaction series. Great for lessons in hardness, cleavage, and crystallization temperature. The color variety among samples offer a visual demonstration of chemical variation. While each specimen will vary slightly in shape, size and color, it will measure approximately 3" in length. Each is individually packaged, labeled & barcoded for easy identification and storage.
