A pendant made from modern dichroic glass. Dichroic glass is glass which can display multiple different colors depending on lighting conditions.. One dichroic material is a modern composite non-translucent glass that is produced by stacking layers of metal oxides which give the glass shifting colors depending on the angle of view, causing an array of colors to be displayed as an example of ...
The color is caused by the size and dispersion of gold particles. Ruby gold glass is usually made of lead glass with added tin. Silver compounds such as silver nitrate and silver halides can produce a range of colors from orange-red to yellow. The way the glass is heated and cooled can significantly affect the colors produced by these compounds.
Dichroism, in the second meaning above, occurs in liquid crystals due to either the optical anisotropy of the molecular structure or the presence of impurities or the presence of dichroic dyes. The latter is also called a guest–host effect .
Neodymium(III) oxide is used to dope glass, including sunglasses, to make solid-state lasers, and to color glasses and enamels. [3] Neodymium-doped glass turns purple due to the absorbance of yellow and green light, and is used in welding goggles. [4] Some neodymium-doped glass is dichroic; that is, it
Artistic glass jewelry is occasionally fabricated to behave as a dichroic filter. Because the wavelength of light selected by the filter varies with the angle of incidence of the light, such jewelry often has an iridescent effect, changing color as the (for example) earrings swing. Another interesting application of dichroic filters is spatial ...
Fused and kiln-formed glass sculpture. Glass fusing is the joining together of pieces of glass at high temperature, usually in a kiln. [1] [2] This is usually done roughly between 700 °C (1,292 °F) and 820 °C (1,510 °F), [3] [4] and can range from tack fusing at lower temperatures, in which separate pieces of glass stick together but still retain their individual shapes, [5] to full fusing ...
