Kyanite is a blue, fibrous metamorphic mineral that forms in distinctive thin blades. This mineral only forms under high pressure within the Earth's crust, which can tell you A LOT about the tectonic history of an area. Because kyanite crystallizes as thin blades, it also crushes up into progressively smaller, elongate crystals during the crushing process.

Our powdered material consists of mostly silt and clay sized particles. Our powders do have a slight grit to them. Please see the corresponding sediment size chart.
