Brazil ianmaterials engineer from [http://www.ufscar.br UFSCar] or the Universidade Federal de São Carlos ("Federal University of Sao Carlos in Brazil. He currently teaches glass related subjects in that University for both graduation and post-graduation as he is the head of [http://lamav.ufscar.br LaMaV] , the Vitreous Materials Laboratory.In may 1998, Dr. Edgar Dutra Zanotto wrote an article in the American journal of physics relating to the false notion that observations of thick glass on old windows translated to the fact that glass is a liquid. Zanotto sought to calculate the flow of glass and found that at 414
degrees Celsius (777 °F) the glass would move a visible amount in 800 years, yet at room temperature he found that it would take glass 10,000 trillion times the age of the earth.
