An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that has occupied mankind for thousands of years.

An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that over thousands of years has absorbed the energies of ancient Egyptians, the Han dynasty in China, Mayan cultures and more - the creation of a "near-perfect" blue pigment. People around the world have sought inorganic compounds that could be used to paint things blue, often with limited success. Most had environmental or durability issues. Chemists at OSU have now discovered new compounds based on manganese that should address all of those concerns. They are safer to produce, much more durable, and should lead to more environmentally benign blue pigments than any being used now or in the past. They can survive at extraordinarily high temperatures and do not fade after a week in an acid bath.
