1. How is colored glass made?
Colored glass, also called heat-absorbing glass, as its name implies, can effectively absorb heat and create a cool indoor atmosphere. The principle of making colored glass is very simple, that is, adding colorant in the firing process of ordinary glass. Adding different raw materials, the length of firing time and the measurement of colorant will affect the color change of colored glass to varying degrees.
2. What are the colors of stained glass?
Generally speaking, the most important factor affecting the color of colored glass is colorant. Adding manganese dioxide to ordinary transparent glass will turn purple; The color of cobalt oxide glass will turn purple; When ferrous oxide or potassium dichromate is added, the color of glass will turn green; Adding cadmium sulfide, antimony sulfide or iron oxide will make it yellow; Adding calcium fluoride and tin oxide will turn milky white; Adding gold trichloride and cuprous oxide will make it red, adding ferroferric oxide, manganese dioxide and copper oxide. The mixture of carbon monoxide will chemically change into black glass.
Advantages and disadvantages of colored glass
Advantages of 1
Colored glass, that is, endothermic glass, is a special kind of glass. Its biggest advantage lies in absorbing heat and enjoying the cool, which is a very good choice for some buildings in the south that have been in a high heat environment for a long time. At the same time, stained glass can also be used for architectural aesthetics because of its beautiful color changes. Colored glass is suitable for some optical instruments according to its own characteristics. In particular, it is necessary to install colored glass on private cars. With the progress of modern science and technology, the transformation of heat energy is gradually generated in colored glass. Of course, the application of these technologies in Nissan's life needs further study.
Two shortcomings
When stained glass absorbs heat, its temperature will also increase with the absorbed sunlight heat. When the heat reaches the zero boundary value of glass, it is easy to cause thermal expansion and cracking. At the same time, the beautiful color of stained glass also determines its poor light transmittance. Ordinary glass is installed in the living room, and sunlight can effectively penetrate the glass, thus playing a certain sterilization and disinfection role. However, once stained glass is installed in the living room, the sun will be effectively blocked, and the benefits of the sun will not be reflected. Moreover, some studies show that the light color produced by colored glass is not natural light color, which will have a certain impact on people's vision. Especially if there are young children at home, it is recommended not to use stained glass for home decoration.
