TissueDB/Materials/Chalk

Chalk is a soft, white form of calcium carbonate (CaCO₃), most familiar as inexpensive, widely available blackboard chalk sold in solid sticks. In medical simulation, chalk sticks embedded between foam layers give a firm, dense insert that is visible under fluoroscopy.^[1]
