Mayan Blue is a 2000-year-old, lustrous turquoise blue that can be seen in ancient Mayan ruins, even to this day. Until relatively recently, no one knew how they made such a vivid paint so resistant to weather, extremes of pH, chemical solvents and biodegradation.
Research conducted largely by PhD student Lori Polette revealed why the mix of organic dye from the indigo plant and inorganic clay is so long-lasting. The clay has a fibrous channel-containing structure. Normally, these channels hold water. What the Mayans did was heat the clay in order to remove the water in the channels. They then mixed it with the indigo. The newly-emptied channels filled themselves with indigo and the result was a paint made from clay which was supersaturated with blue dye.
Nano-technology in action, thousands of years ago!
Our "hero" Lori Polette took her discoveries and, with the help of angel investors, founded a new company, Mayan Pigments Inc. Polette's palette (pun intended) is hoped to generate $10 million in sales within five years by targeting the industrial paints market (plastics, printing, etc.)
Why should we applaud her? Because she is promoting:
You Go Girl!
