Mosaics are an art form used since ancient times as an alternative to painting. Many different types of mosaics can be found, stone, marble and common tiles being the most popular. Nowadays, mosaic tables are coming back in fashion but these kind of tables have been around for a long time with notable differences according to where they have been produced. For example, the mosaic tables in the North of Africa are called "Zellige" style and use natural stone or marble while the European style might use burned clay tiles which are later glazed to give them colour. Each kind of mosaic will have a different resistance and durability depending on it's composition. The core of a mosaic table can also influence the overall hardness and durability of the mosaic. Creating an accurate mosaic depicting real life scenes is an extremely hard and time consuming task.
