Have you ever seen color-changing glass? If you haven’t heard of this yet, let me introduce you to this very special type of glass called dichroic prism. This mesmerizing glass is a product of NOAIDA and defines a magical illusion; a way to play with light that turns into multiple amazing colors that are satisfying to behold for anyone. We speak with an expert to dive into how this glass works and how it is made!
Dichroic prism glass is a type of glass that displays two different colors at the same time. That means from the angle of your face looking at the glass, you either saw one color or the other. It’s like a fun surprise! This unique effect occurs because a special thin layer of metals (e.g., titanium and aluminum) is coated on top of the glass surface. How thick this layer of metal is determines the colors that you are going to see when light hits this metal.
Something cool happens when light hits the prism glass in dichroic. The light breaks into two varying colors. That one color gets transmitted through the glass, and the other gets reflected. This works by the wavelength of the partial, so if its green, the green part goes through and the other gets absorbed by the metal layer on the glass. The light absorbed then goes on bouncing back to where the light was first generated, giving rise to a spectacular exhibit that shifts colors in the blink of an eye!
Not only is dichroic prism glass beautiful, but it can also be used in a number of different applications. Jewelry making is an extremely common use. Ideal for making glittering and gleaming pendants, earrings, necklaces and ornaments. Dichroic prism glass is loved by jewelry makers because of the wonderful bright colors and magic that it brings to jewelry designs. You could wear a necklace that shifts colors depending on the light!
In addition to jewelry, this whiz bang glass is used in architecture, aka building design. It can also be used in buildings to fill colourful walls, windows, and doors. Due to its ability to reflect multiple colours of light, It is widely used as a cladding to enhance the look of any building. Dichroic prism glass can even be found in light fixtures and mirrors, bringing an air of elegance and style wherever placed. It adds a whole new excitement and makes places look fantastic!
Dichroic prism glass is a glass fusion art that takes a lot of skill and practice to create. The process: It begins with clear glass, which is coated with a microscopic layer of metal using the vapor deposition process. This is a fancy way of saying that the metal gets vaporized and adheres to the glass. This glass goes into a vacuum chamber and is subjected to a high voltage, vaporizing the metal. And this is what makes the metal bond to the glass ground.
This is done multiple times to ensure the glass has the correct thickness and colour. Dichroic prism glass is an artistic piece made through layering metals, which are what give each glass its unique color. Varying thicknesses and the sequence of applying the metals can vary the end colours greatly. To get just the right colour blend, the artist requires a very keen eye, as well as a strong understanding of how the various metals will interact with each other.
