Ordinary glass, formed by melting sand and other chemicals together.
Ordinary glass, formed by melting sand and other chemicals together, is an amorphous solid with an irregular structure. And the absorption, reflection and transmission of light by glass is an important reason why it can show different colors.
Colored glass is made according to this principle by adding different coloring agents to the glass raw materials, and this method is also known as the overall coloring method. Overall tinted glass can be divided into light-absorbing tinted glass, light-scattering tinted glass, and electron-excited glass according to the glass coloring mechanism.
Light Absorption Tinted Glass
The principle of light-absorbing tinted glass is that most substances have wavelength-selective absorption of light, i.e., the absorption coefficients of substances are different for different wavelengths of light. For example, the red glass of red light and orange light absorption is very small, on the green light, blue light, violet light can be almost all absorbed, so when white light irradiation to the red glass, only the red light can be through, in the visual red. If the red glass is irradiated with green light, the glass seen will be black.
