Kaolin is a form of clay mostly composed of kaolinite, which is cytotoxic to erythrocytes and macrophages.1 It is found to have pathological effects on the lungs, sometimes leading to radiological lung abnormalities in kaolin mine workers who have inhaled the material, resulting in a tentative diagnosis of kaolin pneumoconiosis. Pneumoconiosis can result in lung inflammation, leading to fibrosis and restricting carbon dioxide and oxygen exchange.2
