Glass Tile / January 4, 2019 / Astrid Hachee
In addition there are two other eminent glass surface treatments for these tiles: slumping and etching. Smalti tile is type of tile which is an opaque glass. It has been in use from ancient times. "Smalti" is an Italian word and refers to a glass paste. Smalti is made by mixing molten glass with metal oxides for color. Translucent Smalti is a popular variant of smalti glass tile. It looks like stained glass with uniform colors. Byzantine Glass is another smalti variant made from thinner slabs of glass. Metallic Smalti is a swirl of a copper-bearing mineral added into the molten glass before it is pressed. Gold Smalti are made by applying a gold leaf and a thin layer of blown glass. Fused Tile is manufactured using the fusion method. In this type a flat glass is cut into tiles shapes and then fired in a furnace. The clear glass will show the tile until treated with a color.
What that means is glass expands and contracts at a greater rate than other materials someone might use in their pool e.g. ceramic or stone. Since the tile is adhered to the bottom of the pool while its expanding and contracting it can easily crack and break if the cement its laid into doesnt stretch with it. Therefore the question often heard from customers is "How do I install glass tile in my pool without having to repair the broken tiles year after year?" The answer has not always been an easy one. However with advances in technology and contractors growing experience installing glass tile we are now able to provide customers with the right recommendations so that their pool installation experiences minimal problems.
The most important step in putting glass tile in a swimming pool is choosing the right installation materials. To reiterate the high rate of expansion and contraction of glass caused by temperature changes is the leading cause of cracks and damage to installed tiles. In order to compensate for this special thin-set adhesives and additives have been developed that expand and contract with the glass. The leading manufacturer of glass-specific tile adhesive systems is MAPEI and their Adesilex P10 thin-set and Keraply additive can be combined into an installation system that is specifically designed for applications where the glass tiles are completely submerged.
