YInMn Blue (/jɪnmɪn/; for the chemical symbols Y for yttrium, In for indium, and Mn for manganese), also known as Oregon Blue or Mas Blue, is an inorganic blue pigment that was discovered by Mas Subramanian and his (then) graduate student, Andrew Smith, at Oregon State University in 2009.
Chemists at Oregon State University created the world's most flawless blue pigment and say the groundbreaking development was pretty much an accident. When the perfect color came into being, the ...
YInMn Blue is an inorganic pigment with an intense blue color that was discovered by Mas Subramanian and his graduate student, Andrew Smith, at Oregon State University in 2009. [ 17 ] [ 18 ] It has been used in water, oil, and acrylic paints from paint vendors including Derivan, [ 19 ] [ 20 ] Golden, [ 21 ] and Gamblin.
Copper pigments. Egyptian blue: a synthetic pigment of calcium copper silicate (CaCuSi 4 O 10). Thought to be the first synthetically produced pigment. Han blue: BaCuSi 4 O 10. Azurite: cupric carbonate hydroxide (Cu 3 (CO 3) 2 (OH) 2). Basic copper carbonate: Cu 2 (OH) 2 CO 3. Iron pigments. Prussian blue (PB27): a synthetic inert pigment made ...
In 2009, his team discovered a novel durable blue pigment, YInMn Blue, [17] the first discovery of a new blue pigment since cobalt was discovered in 1802. [3] [18] Subramanian has given numerous public lectures all over the world on YInMn Blue, including TEDxSalem [19] and TEDxUNC. [20]
The earliest known blue dyes were made from plants – woad in Europe, indigo in Asia and Africa, while blue pigments were made from minerals, usually either lapis lazuli or azurite, and required more. [64] Blue glazes posed still another challenge since the early blue dyes and pigments were not thermally robust.
Cobalt blue is a blue pigment made by sintering cobalt(II) oxide with aluminium(III) oxide (alumina) at 1200 °C. Chemically, cobalt blue pigment is cobalt(II) oxide-aluminium oxide, or cobalt(II) aluminate, CoAl 2 O 4. Cobalt blue is lighter and less intense than the (iron-cyanide based) pigment Prussian blue.
Ultramarine is a deep blue color pigment which was originally made by grinding lapis lazuli into a powder. [2] Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from and as expensive as gold.
