This is really exciting news. I wonder how long it will be before we see the practical application of this new blue pigment. Some laboratory testing involves outcomes that are not always planned. The following is from a northwestern university very close to my home state of Washington.

“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. 

Through much of recorded human history, 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. Cobalt blue, developed in France in the early 1800s, can be carcinogenic. Prussian blue can release cyanide. Other blue pigments are not stable when exposed to heat or acidic conditions.

But chemists at OSU have 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 don’t fade after a week in an acid bath.”
