How Colored Glass Works

Colored glass is a widely used material in all walks of life. It has applications in architecture, automotive design and even eyewear. It controls light transmission, reduces heat gain and protects personal privacy. Therefore, it is a popular choice for both functional and aesthetic display.

To understand the working principle of colored glass, we must first master the basic knowledge of light transmission. Light is made up of electromagnetic waves, including visible, ultraviolet and infrared. Colored glass selectively filters out a portion of the light in the spectrum. So only part of it gets through, and the other part gets blocked.

Visible light is the part of the spectrum we normally see. Ultraviolet light is a type of radiation that can cause damage to skin and furniture. Tinted glass usually blocks most UV rays. Infrared carries heat, and blocking this light helps reduce the heat gain in the room. Further, it also reduces the use of air conditioning. Thus, energy consumption is reduced. The colored glass balances the amount of light entering the space by controlling these three types of beams. Improved personal comfort and building safety.

The function of colored glass depends on its ability to absorb, reflect or transmit light of different wavelengths. This ability also depends on the materials used in the production of colored glass. In general, the working principle of colored glass is divided into the following three parts: light absorption, light reflection and light transmission.

Absorption of light

In the manufacturing process of the colored glass of the body, the colorant added will absorb certain wavelengths of light. Green tinted glass, for example, absorbs ultraviolet and infrared light. This light absorption reduces heat generation in the space while making the interior more comfortable.

Colored glass has the function of absorbing heat. It can absorb a lot of infrared radiation. And infrared radiation is responsible for most of the heat increase in buildings and vehicles. By absorbing this heat, the tinted glass helps to keep the temperature inside and inside the building low. Colored glass can also absorb some of the visible light. Tinted glass reduces glare and improves visibility and comfort in bright conditions.

Reflection of light

Coating or reflecting colored glass works by reflecting light from its surface, especially infrared and ultraviolet rays. This reflection reduces heat and prevents harmful UV rays from penetrating the glass, helping to protect people and furniture inside the building.

Reflective coatings can reduce the production of solar heat by reflecting infrared rays. This will reduce the use of air conditioning, thereby reducing energy consumption. At the same time, reflecting colored glass itself can provide some privacy protection. Because it presents a mirror-like effect on the outside. We can also see things indoors.

Transmission of light

The visible light transmittance of colored glass depends on the degree of coloration. The darker the color, the less light comes through. The lighter the color, the more transparent it is. Visible light transmittance is usually expressed as a percentage, and the lower the percentage, the darker the glass color.

The tinted glass is designed to find the best balance between letting plenty of natural light into the space and reducing heat gain. This is important in the field of architecture. Because what is needed in the architectural field is the effect of natural lighting. Too much heat will only cause distress. In addition to functional advantages, tinted glass can enhance the appearance of buildings and vehicles. A variety of colors and finishes provide architects and designers with a wide range of applications to choose from.
