3.6 – Aliens & Ancient Engineers (9.1.11)


In Aliens & Ancient Engineers, Teotihuacán

…But perhaps the most intriguing aspect of Teotihuacán is the finding by archaeologists, of the extensive use of mica embedded in numerous structures. A mineral only found 3,000 miles away, in Brazil.

“Mica has some electrical properties that make it very good for being an isolator. It resists the transformation of electricity, it’s also very good at being able to be stable at high temperatures so that it can be used in furnace windows and oven windows. It is clear so you can see through it, and at the same time, it stands up to the temperature and electrical discharges.”
