Dec 18, 2011 Hi, Here is the key to the Civilian Chemtrails: They use Boron that is placed in a Lubricity and Fungal / Bacterial chemical placed in the jet fuels distribution. Burning Boron chemicals in jet engine’s makes compounds of Boron that are hygroscopic, such as Boron Nitride and Boric Oxide, BN and B2O3

A boric oxide coating can also generate boric acid layer in ... The friction products were composed of B2O3, H3BO3, SiO2, and FexOy. ... Arc jet test has been utilized to

Borosilicate glasses are basically a combination of silica sand, boric oxide (B2O3), soda ash, and alumina (Al2O3). Lead silicate glasses are composed of silica, lead oxide, and significant amounts of alkali oxide. Opal glasses consist of silica, alumina, zinc oxide, and limestone and dolomitic limestone. Flat Glass

The chemical composition of borosilicate glass typically consists of around 81% silicon dioxide (SiO2) and 13% boron trioxide (B2O3) with lesser concentrations of sodium oxide and aluminum oxide. (Note that the concentrations of boric oxide can vary, 5-13% is typical)
