Split plate
As a split plate two different types are called of plates, both primarily as wall and floor covering are used:
- on the one hand is according to their stratification split building stone from natural stone and
- on the other hand, after the fire , ceramic tiles made of stoneware and porcelain stoneware split along a defined line .
Natural stone slabs
Split slabs made of natural stone are mainly made from easily fissile sedimentary rocks such as slate and Weser sandstone and some metamorphic rocks such as quartzite .
Slate can often be split with little effort and so thinly and evenly that it can be used to make roofing slate panels and slates up to 6 mm thick .
Ceramic plates
Ceramic split tiles are ceramic tiles that are dealt with in DIN 14411 . The green compacts are produced by extrusion and, like slotted bricks, are given a number of continuous hollow chambers in the longitudinal direction. The hollow chambers lie in the middle on a line and thus define a predetermined breaking point along which the panels are split after the fire. Half of the webs between the hollow chambers remain on the back of the right and left split plates. At around 20 to 30 mm, split tiles are therefore much stronger than modern ceramic tiles and have a grooved reverse side that enables a good bond with the adhesive mortar when they are laid. The stoneware double slabs are fired at over 1200 C.
Glazed split tiles
Split ceramic tiles were often used as wall and floor coverings in the 20th century . They are also suitable as a covering for stairs, terraces and balconies. The rectangular, colored glazed split tiles in light blue, pale yellow and pink tones on the walls of Berlin subway stations are well known. Occasionally, glazed split tiles are also used as facade cladding.
Unglazed split tiles
Split clinker , as well as split facing bricks (flat and economy facing bricks ), are often used as facade cladding .
