Ooh, I like this new blue:

Blue pigments of the past have often been expensive (ultramarine blue was made from the gemstone lapis lazuli, ground up), poisonous (cobalt blue is a possible carcinogen and Prussian blue, another well-known pigment, can leach cyanide) or apt to fade (many of the organic ones fall apart when exposed to acid or heat).

So it was a pleasant surprise to chemists at Oregon State University when they created a new, durable and brilliantly blue pigment by accident.

The researchers were trying to make compounds with novel electronic properties, mixing manganese oxide, which is black, with other chemicals and heating them to high temperatures.

Then Mas Subramanian, a professor of material sciences, noticed that one of the samples that a graduate student had just taken out of the furnace was blue.

“I was shocked, actually,” Dr. Subramanian said.

In the intense heat, almost 2,000 degrees Fahrenheit, the ingredients formed a crystal structure in which the manganese ions absorbed red and green wavelengths of light and reflected only blue.

When cooled, the manganese-containing oxide remained in this alternate structure. The other ingredients — white yttrium oxide and pale yellow indium oxide — are also required to stabilize the blue crystal. When one was left out, no blue color appeared.

The pigments have proven safe and durable, Dr. Subramanian said….

It looks very similar to the famous Yves Klein blue, as in his painting at the Tate:

"In 1947, Klein began making monochrome paintings, which he associated with freedom from ideas of representation or personal expression. A decade later, he developed his trademark, patented colour, International Klein Blue (IKB). This colour, he believed, had a quality close to pure space, and he associated it with immaterial values beyond what can be seen or touched. He described it as ‘a Blue in itself, disengaged from all functional justification’. Klein made around 200 monochrome paintings using IKB. He did not give titles to these works but, after his death, his widow assigned a number to each one."

This one is no. 79 – or, to give it its full title, IKB 79. How it differs from IKB 78 or IKB 80 I really couldn't say, but despite the dubious metaphysical claims these pictures are quite stunning when you see them live. Reproduction here doesn't begin to do it justice. Pure vibrant colour…

I look forward to seeing a large canvas of this new Oregon Blue…unless, of course, Yves Klein's lawyers decide that it's a breach of patent.
