Word origin

The word 'cobalt' originates from the German word 'kobalt' or 'kobold', which means goblin or evil spirit. This is because miners in the past found cobalt ore difficult to smelt and believed that it contained evil spirits. Cobalt was discovered by Swedish chemist Georg Brandt in 1735. It has been used for centuries in the production of blue pigments for ceramics, glass, and paints. Today, cobalt plays a crucial role in various industries, including battery production, aerospace, and healthcare.
