USED MATERIALS
The saxonian sandstone has been successfully used for centuries as material for contructing al like as sculpturing. Although there is a wide variety of different types of this stone all can be carved very easily in comparison to granite, limestone or marble. When I became acquainted with the snow-white Laaser marble from South Tyrol, I had to change my working methods completely. In fact it is a relatively hard and extremely brittle stone, which does not allow for much flexibility and clearly shows any flaws. Unique to this stone however is its silky, delicate surface, which has a translucency characteristic of marble.
The saxonian/bohemian sandstone resulted from sedimentation at seaground during the cretaceous period around 100 million years ago. There are tree different qualities and characteristics. Hardness, grit, colour, pressure strength, absorbency and weather proofness are part of it. While the grain consists of quartz, silicic acid (likewise quartz, but in liquid form), lime and clay occur as binder agents. Therefore the different types of sandstone are characterised according to their binder:
Posta sandstone (silicac acid bound)
Reinhardsdorf sandstone (silicac acid/chalk bound)
Cotta sandstone (silicac/clay bound)
There are naturally used other types of stone that come originally from the region:
Lausitz granites, gabbros, basalts,
Red-Meissen granite,
Hilbersdorf and Rochlitz porphyry tuffstone,
Oberdorla shelly limestone,
Loebejuen quartz-porphyry,
Beucha granite-porphyry,
Neuensalza diabase
