Chalk is abundant in west-central Kansas and is as representative of Kansas geology as the sunflower and the cottonwood tree are of the state's plant life or the meadowlark and buffalo are of the animal kingdom. Furthermore, chalk has been a part of the Kansas region not for centuries but for thousands of centuries.National Audobon Society Field Guide to North American Rocks and Minerals. Alfred A. Knopf.

It is often associated with marine environments and is characterized by its distinctive white color and powdery texture.
Calcite. Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3 ). It is a very common mineral, particularly as a component of limestone. Calcite defines hardness 3 on the Mohs scale of mineral hardness, based on scratch hardness comparison. Large calcite crystals are used in optical equipment, and limestone ...Mineral paint is more durable than chalk paint because it is designed with a built-in top coat. This top coat is resistant to moisture and chipping and protects the finish from different elements. On the other hand, chalk paint doesn’t have a topcoat. So, the paint isn’t durable enough to withstand moisture or water for a long time.Clay and quartz are the most common impurities. Most chalk is soft friable rock, easy to mine.

Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.
