Materials

Ornamental stones represent a natural building material whose usage is dating far back into the period of Ancient history.

Interest in ornamental stone has increased in the Czech Republic lately; not only in context of repair and reconstruction of historical or church buildings. Nowadays, ornamental stones are used when building new, modern houses and other projects.

Characteristics
of ornamental
stone

Stone as a raw material for products must meet a wide range of requirements. Physically-mechanical properties are the primary criterion. A product made of stone will permanently work by its shape, structure, colour and surface finish. Stone-cutting products are made of a good quality material, i.e. a compact one without apparent disruptions. Besides that, as for some kinds of products a clear structure with a minimum occurrence of nodules, schliers or other anomalies is required. The Czech raw material base has limited sources of balanced mineral reserves of a quality meeting these requirements. Over recent hundred years many small quarries have been exhausted the while other ones have been left as a result of low exploitation effectiveness or due to the fact that mining of sufficiently sized blocks, which are necessary for effective processing by means of slabbing/ stone saws, was not feasible.

Clasiffication of

by origin
Variety of stones are based on many processes of mineral forming. Physico-mechanical and technological parameters of stones are different because of magmatic, sedimentary and metamorphic origin. Schéma hornin

rocks

According to a place of origin, rocks are sectionalised into three basic categories of abyssal, hypabyssal and effusive rocks. Then, based on their structure, size and shape, they are divided into coarse-grained, medium-grained, fine-grained and compact rocks. An even habit of some rocks is in places eroded by phenocrysts, which add interest to these rocks. Structure of the coarse-grained rocks is determined by a very long time of magma solidification and a possibility to create larger crystals of individual minerals. Time of fine-grained structures solidification was significantly shorter. The texture presents an arrangement of rock-forming materials in space. As for processed rocks it is usually omnidirectional with regularly laid out particles. Both the structure and texture influence the durability and workability of stones.

The most frequently processed kinds of igneous rocks are granites and granodiorites. They mutually vary in the proportion of represented minerals (feldspars).

Other kinds of igneous rocks such as syenite, diorite, diabase and gabbro belong to notable materials mainly with respect to their colour and structure. Their other properties are not very different from the granite category features nor otherwise significant as for the term of their erosion resistance.

Speaking about light igneous rocks, trachyte is worth mentioning. Because of a limited choice of igneous rocks´ colour classes an import from other countries and continents is rising.

When classifying sedimentary rocks we distinguish sedimented and consolidated particles of disintegrated rocks (so called clastic deposits) from rocks arisen from a chemical or biochemical process. The clastic rocks, which are used for the stonemason´s production, include mainly sandstones, marginally also marlstones and arkoses.

Individual classes of rocks vary both in their composition of elements and syntaxial cement, which significantly influences workability and durability of the stone. For processing other classes of sedimentary rocks so called ´carbonaceous rocks´ - limestones containing a vast proportion of C and CO3 may be used. Though these rocks are very solid, they have a lack of resistance when used for exteriors. Therefore, they are used especially in interiors.

Sandstone and marlstone are easily processible materials. In the history, they were locally used for various constructions. Sandstone and marlstone deposits were created in sea and lake basins of Česká křídová tabule (Bohemian Cretaceous Basin), and in Moravia in Carpathian flysch. The contemporary state presents just a fraction of mining locations. The raw material was partially exploited and limited because of housebuilding. Prohibition of using minerals in nature conservation areas (Adršpašské skály, Český ráj, Hřensko) have also not inconsiderable influence on this state. Extraction is performed in only few regions - mainly in quarries in Podkrkonoší and Teplicko or, in isolated cases also in Bohemia and Moravia. In past centuries, graywacke used to be locally utilised for constructions in Drahanská vysočina. Today it is a main raw material source for gravel production.

Limestones are created by calcite containing various admixtures, colour of which varies according to the rock structure. Chemical sediments were created by a precipitation from a water solution or its crystallisation. Organogenetic sediments have their origin in skeletal remains and bodies of miscellaneous animals (Barrandien region). Considerably larger amount of limestones is extracted for different utilisation (production of gravel, lime and cement, chemical and food processing industry) but only a little amount of quarries offers sufficient solidity and compactness. Unfortunately, the rainbow of colours of limestones and marbles extracted in our country is poor as well.

In particular geological phases, both igneous and sedimentary rocks either underwent a contact metamorphism or by means of this metamorphism they affect a larger regional area. While some limestones gave rise to marble, slate originated from claystone sedimentary rocks. Marble deposits are of a smaller size, they often create just a pocket in surrounding rocks, e.g. in paragneiss. Olivenes gave rise to marmolite, a variety in the serpentine group minerals. It is deep green, colour-attractive rock which occurs in Czech Republic only in little pieces. Its weather-proofness is rather limited. Rare occurrence of earlier extractions of marmolite doesn´t enable its more extensive use (Kremže u Českého Krumlova, Kutná Hora, Letovice).
