Usage of Gold in Glass

Gold has a great number of uses when it comes to the production of glass. For the most part when it comes to making glass is the pigment that is used. A little bit of gold is suspended in the glass and when it is annealed it brings about an impressive crimson color. Gold is also utilized for making special glass for climate controlled buildings as well as in cases. This process is carried out by a little bit of gold being spread inside the glass or coated onto the surface of the glass that helps to reflect the solar radiation out and assists in keeping the buildings cool during the hot summer months and then it can also reflect internal heat inside and keep the building warm during the winter months.
