If you need just one reason to consider mosaic tiles, then it has to be the plethora of unique designs or artworks. Mosaic itself is a work of art, unlike other types of tiles where the best you can do is go for some patterns and distinct colours. Mosaic tiles would not be a whole different category without the artwork because it basically uses the same materials that are already used to make other tiles.
It is unfair to simply call mosaic tiles a work of art without delving into the details of creative brilliance that is achieved by most credible makers. You can always go for an organic mosaic tile, which is made from a completely natural material without any added chemical or other ingredient. You can go for limestone or basalt, granite or marble. These natural stones have little impact on the environment and there is no chemical residue, fume or traces to deal with. You could buy mosaic tiles as individual squares or sheets. However, where the creativity gets interested is when organic materials such as natural stones get blended with different materials, from glass to ceramic and china, thereby creating amazing mosaic tiles!
Many types of creative tiles are made from smaller pieces of different materials. Some makers crush wine bottles, marbles, glass, china and even jewellery, blend them in unique compositions to come up with a special kind of mosaic tiles. These can be handmade or mass produced. The uniqueness is starker in handmade mosaic tiles. It is not just the use of different materials, as sheets or individual pieces or as crushed. It is also not just about the colours. Many tile manufacturers weave magic into mosaics by playing with the treatments meted out to the glass.
You will come across three distinct types of mosaic tiles made from glass. These are iridescent, metallic and swirled. Iridescent is a process of glass firing wherein mineral salts are added to create a pearlized appearance in the tile. The result is amazing. Metallic glass mosaic tiles are made by adding very small flakes of metals that are then swirled in the glass before it is fired. This process lends a spectacular shimmer firmly embedded in the tile. The swirled process involves mixing glass of different hues to complement the base colour. The result is different levels of depth marked by distinct colours. The effects usually vary among the pieces of mosaic tiles.
