Ceramic steps - practicality and durability
Practicality and durability -is a suitable and well known variant. All Mediterranean architecture, since the most ancient times, has been based on application of ceramics level with a stone. And many ladders of the Middle Ages reveted with tile, serve not only museum pieces. Today, when we choose materials for facing the ladder, there are complexities - the list of possible variants is so much longer. We shall try to announce it even in general.
If to describe “know-how” of ceramics in brief, it is possible to reduce all to temperature of roasting - the higher the temperature of roasting is, the more strongly material will be. Though, everything depends on structure of clay weight, technology, modes of roasting.
Red (yellow) clay:
Terracotta - clay, burnt at the temperatures from 500 up to 900 degrees. It is not covered by glaze. Moisture absorbs very actively. Durability is low. Products from terracotta are used as decorative or as capacities for dry substances and products. At the negligent reference becomes soiled. Usual building brick of red color is also terracotta.
Majolica - it is the same terracotta, but covered with glaze or ceramic enamel. Durability is higher than at terracotta. If glazing technology was kept (in glaze there is no lead, the factor of expansion of glaze coincides with similar factor of clay weight - it means there are no cracks), it can be used as utensils for foodstuff, otherwise - only as a decorative product. If roasting has been made on the maximal temperature mode, it can serve as a covering of walls, a floor, a ladder in an interior of the individual house in conditions of sparing operation. It is traditionally used in furnish of fireplaces and furnaces.
