The structure of the electronic database of natural stones used in the Czech Republic (named Deka) has been completed. The system is based on MySQL, and is comprised of the following crucial items: general data, data regarding the geographic location and status of the quarry; petrographic description, associated mineralogical data and chemical analyses; technical data covering physical and mechanical properties as well as sculptural workability; parameters about the deposit (quarry); and data describing historical exploitation and utilization. Along with the structure of the database, other practical problems such as access to the database, insertions, corrections, erasing a record or reference, etc. are discussed. The database is designed for geologists, historians and restorers resolving problems of a stone's provenance from monuments, architects involved in the selection of promising stone types for new projects and for educational purposes to geologists, restorers, etc.
Appendix 1: A description of the eight types of data used in the dimension store database is provided at http://www.geolsoc.org.uk/sup18394
Figures & Tables
Natural stone is considered to be a versatile, durable and aesthetically pleasing building material. From the beginning of civilization, important structures and monuments have been built from, or based on, natural stone. Until the end of the nineteenth century, the use of local stone resources was mostly in balance with the local environment. Strict environmental legislation has resulted in the closing of many long-standing quarries in industrialized countries, which has led to a shortage of traditional stone varieties. This has caused problems for restoration practice. Cheap, imported stone from less industrialized countries has become more widely available in recent years.
Some of the issues related to built stone conservation and restoration covered by this volume are: the establishment of inventories of possible replacement stones; understanding the decay mechanism and use of preventive conservation methods for slowing down decay processes; evaluation of the properties of natural stone; and assessing the risks of using replacement stones of different qualities.
