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. Its mineral density makes it radio-opaque, so it appears bright under fluoroscopy and X-ray much like bone. This radio-opacity makes it usable as a low-cost radiographic bone stand-in in simulation.^[1]
