Glass Tile / January 10, 2019 / Karlotta Boule
The reason for doing this is when installing the glass tiles you do not want to see the trowel marks through the glass tiles. Another key to think about when installing the translucent tile is to make sure the surface behind the tile is white. If you have a painted kitchen and the walls are currently a dark or strong color that color could appear through the glass tile. If installing the translucent tile make sure the surface is painted white first and make sure the use of white thin set as well. The second type of glass is where the glass itself is a crystal type glass with the color backed on the back. Most 4mm or 8mm crystal type glass is clear and then the color of the tile is applied on the back of the tile giving it the color.
Although the definition of clear/translucent glass is "allowing light to pass through partially or diffusely" it doesnt mean that all clear glass tiles are transparent in a way that you can see for example an object or your hand behind it. Clear glass is the material used to make these tiles but they can have color or not. There are basically three types of clear glass tiles: back colored stained and plain or non-colored. Back colored clear glass mosaic tiles are by far the most popular in the market. The tiles are made of clear/translucent glass usually from 4mm to 8mm thick and they receive a coating/painting on the back during manufacturing which is what gives the color to the tile.
Usually they are available mesh mounted on a fiberglass sheet or as field tiles such as subway 3"x6" 4"x4" 6"x6" and even 12"x12". Stained clear glass tiles are made of clear/translucent glass that are stained during its manufacturing process and then cut into multiple pieces. In this case you can see all the way through it even if it has a dark stain color and that is the reason they are not mesh-backed otherwise you would see the mesh through the glass even after installed. Instead they are mounted on clear-faced or paper-faced sheet. Plain or non-colored clear glass tiles are made of clear/translucent glass and do not have color in it. Though the word "plain" is used to describe these types of tiles they are extremely elegant and easy to work with if you want to give a special "touch" to a kitchen backsplash bathroom and shower or swimming pool.
