Black Chasm Cave Black Chasm Cavern are derivative of the marble bedrock, containing primarily calcium or calcium carbonate (CaCO3). There are a variety of formations in Black Chasm Cavern, including stalactites, stalagmites, columns, flowstone, draperies, ribbons, angel's wings, cave bacon, soda straws, helictites, false floors, and others. Black Chasm Cavern is home to amphipods, which live in the lakes of the cave. The amphipods are adapted to life without light, having no pigmentation or eyesight. Also living within the cave, and adapted to total darkness, is the Banksula grubbsi arachnid. Related to the harvestman, the Banksula grubbsi has a multi-segmented body that appears
Sodium carbonate sodium sulfate was blended with crushed limestone (calcium carbonate) and coal, and the mixture was burnt, producing calcium sulfide. The sodium carbonate was extracted from the ashes with water, and then collected by allowing the water to evaporate. The hydrochloric acid produced by the Leblanc process was a major source of air pollution, and the calcium sulfide byproduct also presented waste disposal issues. However, it remained the major production method for sodium carbonate until the late 1880s. In 1861, the Belgian industrial chemist Ernest Solvay developed a method to convert sodium chloride to sodium carbonate using ammonia. The Solvay process
