Optical brighteners: Colorwise

01 Mar 2014

Optical whiteners, Britemax, are fluorescents or molecules that absorb wavelengths of dark colors and UV-light. The result is that an electron in the fluorescent molecule is excited to a higher energy level. When that electron fallsback, it sends out a photon; aka energy in the form of light. The wavelength of this emitted light is… Read more

Metasilicates: protective and aggressive

01 Feb 2014

Sand is the raw material for metasilicates (Na2SiO3). Sand is a mixture of silicates, with quartz as the most known crystal form. When sand is molten together with soda at 1000oC, the reaction product solidifies at room temperature and forms glass. Glass, as a consequence, is also a mixture of silicates. This glass is dissolved in… Read more
