Will craft glass fade or deform under long-term sunlight exposure?

Craft glass is widely used in many fields for its exquisite appearance and unique decorativeness, but people often care about whether it will fade or deform under long-term sunlight exposure.
Generally speaking, the performance of craft glass depends largely on its manufacturing materials and craftsmanship. If high-quality glass raw materials are used and well processed, such as high-temperature tempering or special chemical treatment, its weather resistance is usually relatively good.
However, even high-quality craft glass may change to a certain extent under long-term direct sunlight. For some craft glass with colored coatings, painted or printed patterns, ultraviolet rays in the sun may cause the color to fade gradually. This is because ultraviolet rays destroy the chemical structure in the pigment, causing it to lose its original color and brightness.
As for the problem of deformation, ordinary glass will soften and deform at high temperatures, but if craft glass is properly tempered, its heat resistance will be significantly improved. However, extreme high temperatures and long-term sunlight exposure may still affect it, especially when there is local stress concentration or quality defects in the glass.
In addition, the peripheral seal and support structure of craft glass will also affect its stability under sunlight. If the seal is not good, moisture and air may enter the interior of the glass, accelerating aging and deformation under the action of sunlight and temperature changes.
In order to reduce the risk of fading and deformation of craft glass under sunlight, you can choose a coating or film with UV resistance, or install it in a location that can avoid direct sunlight. At the same time, regular cleaning and maintenance will also help maintain the performance and appearance of the glass.
In short, whether craft glass will fade or deform under long-term sunlight cannot be generalized and depends on many factors. However, through reasonable selection, installation and maintenance, these adverse effects can be minimized, the service life of craft glass can be extended, and its aesthetic effect can be maintained.
