Glass Tile / January 15, 2019 / Genevieve Brunelle
In this method colors are added to the top or bottom of the glass. Fused glass tiles are characterized with a translucent area and a layer of opaque color visible through the tile. These tiles are further treated with an etching or other coating for aesthetics or abrasion. Sintered tile is a variety made by pressing glass powder into dies and then heated until the particles fuse. The color is either added into the powder or added topically after cooling. Unlike smalti tiles sintered tiles tend to have a uniform look. This milky and scratch-resistant finish makes it versatile. Cast tile is made by inserting chunks of glass into a mold which gives it a layered look.
In situations where glass tile is exposed to extreme temperature differences an elasticizing polymer is added to the mix allowing the grout to stretch and flex preventing breaks from occurring in the delicate glass tiles. Using a grout float scoop a manageable amount of grout onto the float. Start at the farthest or highest spot away from you and spread the grout in between the tiles diagonally across the pattern. Dont worry about getting grout all over the tiles. The grout must be firmly pressed into the grout lines with the grout float covering all spaces and voids. Once a 3x3 section of grout has been applied to the tile use the small rubber edge of the grout float to remove about a third of the grout from between the tiles.
The first type of tile is a translucent glass. A translucent glass is a type of tile that you could actually hold up and see right through it. The most common types of glass that is translucent is a recycled glass or an oval penny round or brick type of tile. Majority of translucent glass tiles are paper faced. The reason that most of these are paper faced is because the mesh backing can be seen through the glass tile. When installing this type of glass tile you want to use a small notch trowel when spreading your mastic on the installation surface. After spreading the mastic you will want to flatten down or knock down the trowel marks.
