Spanish Researchers Make Astounding Mayan Discovery!

May 3rd, 2013|chemical analysis|

 

Recently, a Spanish group of chemists discovered a new pigment in the famous Maya Blue paint.
Known for its resiliency to harsh environmental conditions and vibrant color, Maya Blue has remained more of a mystery than not for centuries.  Through earlier chemical analysis, researchers discovered the two main components of the paint – indigo (pigment) and palygorskite (type of clay).
 
 
Finding these two ingredients weren’t hard.  Researchers and chemists knew there had to be at least two ingredients – 1) a source of color and 2) a thick base that the color could attach itself to.  They found these easy enough, but they knew there was something missing – a secret third ingredient.  It’s speculated that this ingredient is responsible for the paint’s durability and sticking qualities.
But this isn’t what the Spanish researchers found.  They did, however, discover something equally impressive.
Dehydroindigo – a yellow dye. 
The reason this is impressive is because Maya Blue was thought to only contain one dye for centuries.  Indigo and Maya Blue were used synonymously by researchers and the public when, in reality, they had different chemical makeups.
Speaking on the findings, Antonio Doménech, one of the researchers from the University of Valencia said, “We detected a second pigment in the samples, dehydroindigo, which must have formed through oxidation of the indigo when it underwent exposure to the heat that is required to prepare Maya Blue.”
Doménech also said that he believed the Mayans played with the heat temperature during production to make the paint greener or bluer.  The more heat added during the baking process, the greener the paint would become from the higher levels of dehydroindigo.  After the chemical analysis, he made a conclusion that made sense of Mayan Blue’s unique blue color.
“Indigo is blue and dehydroindigo is yellow, therefore the presence of both pigments in variable proportions would justify the more or less greenish tone of Maya Blue,” Doménech explained.
Although the third ingredient of Maya Blue still remains a mystery, the Spanish researchers discovered something equally enlightening, dehydroindigo: a previously unknown fourth ingredient.  Through chemical analysis, though, Doménech and his colleagues are determined to discover the third ingredient in Maya Blue – an ingredient that has remained a mystery since the fall of the Mayans.

Bringing new products to the market is an expensive proposition and our professional chemical analysis services are the proactive way to limit any financial liabilities before they occur. Thoroughly testing goods before they are introduced to the general public is imperative because many consumer goods are produced from chemicals that could potentially pose a serious threat to the planet and life in general. Our team of experts regularly works with leading industries, and our clients always know the best ways to protect consumers and eliminate the introduction of contaminants to the environment.

Our suite of services include expert analysis by a state-of-the-art lab that is staffed with experienced professionals, so clients always get accurate results from our chemical analysis of any products. We routinely test for contaminants and take pride in helping clients ensure the safety of their own customers. Reverse engineering is another essential way to ensure consumer protection, and our services provide further insight into the chemical makeup of a particular product. This ensures that if the component parts break down over time, manufacturers know the different chemicals that may be released.

Ensuring the purity of a particular product is another option that we offer our clients, and our chemical analysis services are the proactive option for clients in the pharmaceutical and food industries. We also offer expert problem-solving that relies on our chemical analysis services to make the minor adjustments that some products require during the manufacturing process. During the research and development phase, we work directly with many of the leading industries and assist our clients with professional service, timely results and a positive feedback loop.

With professional chemists on staff and the latest laboratory equipment at our team’s disposal, our services are the proactive way for manufacturers to address the issues of purity, contamination and consumer safety. We also provide problem-solving services and routinely provide detailed information about deformulation and quality control.
