 The word cobalt is derived from the German kobalt, from kobold meaning "goblin", a superstitious term used for the ore of cobalt by miners.
 Cobalt compounds have been used for centuries to impart a rich blue color to glass and ceramics. Cobalt has been detected in Egyptian sculpture and  jewelry from the third millennium BC.
