Glass Tile / January 11, 2019 / Odette Pinneau
Their craftsmen work the glass by hand to transform each tile into a piece as unique as a snowflake. Bisazza glass tile uses the highest quality ingredients and constantly works to improve the production process to result in stronger materials with more vibrant colors. Shortcuts in production and compromises with materials result in a finished product lacking perfectly squared edges color quality and strength. To the untrained eye the product may look similar in display but it is in fact extremely inferior. Quality producers of glass tile may also apply a bevel to each of their tiles to allow for more level and consistent surfaces during installation.
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.
For the past five years I have witnessed an unprecedented increase in the use of glass tile mosaics in residential and commercial applications. As with many other high end popular products cheaper knock-offs have quickly flooded the market. Unsuspecting consumers purchase these attractive-looking cheap tiles only to become frustrated months later when they learn the investment in their home is not only worthless but also costly. When a glass tile installation or product fails homeowners are left with expensive tear-outs and repairs. To the end user and many untrained contractors the quality differences may seem subtle but these distinctions have a major impact on the final appearance and durability of the project.
