What Color Glass Blocks UV Rays? The Theory Behind Colors

Glass bottles have been made as early as 1000-1500BC, and the glass and bottle industry started in America in the early 1600s. If you’re a skincare maker or user, I am guessing you have heard of ultraviolet glass jars. This is a special type of glass that many formulators use to maintain the integrity of their products naturally. Even though it looks violet, the color seems to be black.

Ultraviolet Glass Bottles and UV Rays

When something is exposed to light, it is bound to react. Moreover, plants exposed to light tend to grow, which causes dead plants to wither. On the other hand, light fades our wood decks and wrinkles our skin over time. It can be degrading as it is life-giving at the same time. Furthermore, clear glass allows light in the visible spectrum to penetrate through. Hence, this causes products to degrade more quickly and encourages microbial growth. Additionally, violet glass is different, it filters out light in the visible spectrum, letting in only UV light and infrared.

With help of visible light being absent, this helps the product resist degradation. Hence, this increases its shelf life. Additionally, even though violet glass filters out visible light, it also lets in UVA and UVB rays, which actually suppress microbial growth.

The Science of Color and What Makes the Color of Glass Important

There is some information you need to learn about ultraviolet and amber glass bottles. We promise to not make this a science class but let’s learn a bit more.

Sir Isaan Newton brilliantly discovered that light has different colors, every color has its respective frequency, which makes them unique from each other. Moreover, visible light is called “visible” because it’s what we humans see.

Fun fact: did you know that the colors you see on every surface or object are the reflection of light? according to Infinity Jars. When we speak literally, the color orange doesn’t have the color orange and the apple doesn’t have a yellow color when we bite into it. So, why is the color of the glass bottle so important?

The sun can be quite a bully when it comes to ultraviolet rays and radiation. Moreover, UV rays and radiation has harmful effects. This includes sunburn, skin cancer, eye damage, and the premature aging of your skin which causes sagging and wrinkles, and we don’t want that!

The glass’s color is significant because it indicates the types of light that can enter through its surface. The red glass allows for red light, blue glass allows for blue light, and so on. Different impacts on the contents of a glass bottle or container can result from the sort of light that can pass through its surface.

Light sensitivity varies based on the following:

• The intensity of the light source
• The kind of light that the source is emitting
• The length of exposure
• Component of food’s oxygen
• Temperature Source separation from the food

Ultraviolet Glass Bottles: Protection from UV Rays

If you look at an ultraviolet glass bottle, it may appear to be black. However, they are actually violet when you hold them to the light. Moreover, almost all colors are absorbed by ultraviolet glass, making it black in appearance.

Due to its effectiveness in preventing the growth of microorganisms, UV light is also employed in laboratories to purify water and air. Only UV light may penetrate through the surface of ultraviolet glass containers, which shield contents from germs and other pathogens. So, if you are wondering what color glass blocks UV rays, ultraviolet glass is the one!
