Research of argillaceous matter and geological observation of clay raw materials have a long history in Czech lands. Details of this history, with 145 citations, were reported by Konta (1961). Roots of the Czech National Clay Group are generally seen in an increased concern and research activity focused on clay minerals and argillaceous rocks at the Department of Petrology, Charles University in Prague, in the years 1950 - 1957 under the leadership of Prof. J. Konta.
In this centre of clay research and teaching at the Faculty of Sciences regular seminars were organised, and diploma works or doctor theses in clay science were defended. The first three conferences on clay mineralogy and petrology (started in 1958) were held at this place.
Officially, the Czechoslovak National Clay Group was founded in 1963 under the organisational mantle of the Czechoslovak Association for Mineralogy and Geology joined with the Czechoslovak Academy of Sciences. The first scientific conference on clay minerals and argillaceous rocks in the former Czechoslovakia was organised at Charles University in Prague. The second one, held in Prague too, had already a broad international participation.
1958: 1st conference in Prague (Bohemia)
1961: 2nd conference in Prague (Bohemia)
1964: 3rd conference in Prague (Bohemia)
These three conferences were solely organised by the Department of Petrology (Charles University).
1967: 4th conference in Košice (Slovakia)
1970: 5th conference in Prague (Bohemia)
1973: 6th conference in Prague and in Kutná Hora (Bohemia)
1976: 7th conference in Karlovy Vary (Bohemia)
1979: 8th conference in Teplice (Bohemia)
1982: 9th conference in Zvolen (Slovakia)
1986: 10th conference in Ostrava (Moravia)
1990: 11th conference in České Budějovice (Bohemia)
These conferences were organised within the framework of the Group on Clay Mineralogy and Petrology being a part of the Czechoslovak Society for Mineralogy and Geology of the Czechoslovak Academy of Sciences.
1992: 12th conference in Bratislava (Slovakia)
1994: 13th conference in Prague (Bohemia)
1996: 14th conference in Banská Štiavnica (Slovakia)
1998: 15th conference in Brno (Moravia)
The above mentioned conferences were organised by the Czech and Slovak National Clay Group.
In 1991 the Czech and Slovak National Clay Group was registered as an independent scientific society. At first, Czech and Slovaks formed a single organization. The conferences on clay mineralogy and petrology were organised alternatively in the Czech and Slovak Republics. After the conference in Brno this jointly working group was split into the Czech Clay Group and the Slovak Clay Group.
The edition of conference volumes after each meeting became a tradition. Conference volumes do not exist for the 12th and 14th conferences, because some papers were preferentially printed in the journal Geologica Carpathica-Clays, published by Slovak Academic Press Ltd., Bratislava. Conference proceedings were not published from 19th conference.

At this opportunity the following program was presented:
The spring meeting was held on June 4. Two lectures were presented:
The autumn meeting was held on December 4. Three lectures were presented :

The Czech National Clay Group organized two seminars in 2004. Both of them took place in Prague in the building of the Czech Geological Survey, Klárov 3, Prague 1.
The first, spring meeting was held on May 26. Following lectures were presented:
The second, autumn meeting was organized on December 1.
Main lecture was delivered by K. Novotná : Mineralogy of kaolin from Kadaň region.
Afterwards M. Šťastný summarized the results of the XVIIth Conference on Clay Mineralogy and Petrology.
In the year 2004 two numbers (28 and 29) of the bulletin Informátor were edited.
It was held in Prague, in the building of the Faculty of Sciences, Charles University, from September 13-17, 2004 and prepared by the Institute of Rock Structure and Mechanics and by the Institute of Geology, both the organizations belonging to the Academy of Sciences of the Czech Republic. Forty six specialists participated in this meeting, 22 of them from abroad, of 15 countries of the world. The conference was opened by K. Melka, chairman of the Czech Group.
To attract people from Czech enterprises, it was decided to arrange Seminar lectures in Czech language, concentrated on sorbent and sealing clays, the first day. Foreign participants obtained printed materials in English and could participate in the discussions. This seminar was prepared by J.Konta and a part informing in the research of the crystal structure and the crystal chemistry of clay minerals was delivered by Z.Weiss. Other days, the lectures were delivered in English. Themes of original contributions were concentrated again on sorbent and sealing clays, on ecology, properties of clays, problems in mineralogy and geology of clays, soils etc. and on the utilization of clays in industrial application. These were also subjects of the poster exhibition. A free poster and a desk were available for publicity of the journal Clays and Clay Minerals by D.C.Bain.
Two invited lectures were presented:
Two excursions were on program:
(1) Foot excursion through the historical core of Prague with the demonstration of weathering effects on stones in buildings and statues.
(2) Geological excursion to Přední Kopanina quarry, west of Prague; visit of the golden opuka(marly chert), which is famous medieval stone used by builders and sculptors mainly in the 9th - 15th centuries in Prague and Czech Lands.
Participants of the Conference had opportunity to take part in the excursion to the ancient mining town of Kutná Hora, organized by the agency ITC Travel and Conference.
On the whole 23 original oral contributions were presented and 16 posters exhibited.
Conference Proceedings will be edited within the journal Acta Geodynamica et Geomaterialia. Roughly 20 contributions will be published.
During the conference the plenary meeting of the Czech National Clay Group took place.
The new council for the next period was elected: K. Melka, M. Šťastný , J. Konta, B. Křelina, Z. Weiss, L. Aron, M. Holý.
K. Melka decided not to put up himself as a candidate for a chairman. Afterwards M. Šťastný was elected to the chair.

Informátor 50 published reviewed article: “Way to microworld” by Vojtěch Kapsa and Lubomír Skála with following abstract: “In this paper, differences in understanding physical reality in classical and quantum physics are discussed. Classical physics, as a result of our effort to describe the world around us, operates with intuitive concepts related to our everyday experience. It assumes that it is possible in reality to approach arbitrarily close to simple idealizations like the perfect isolation of the system from its surrounding, in principal arbitrary accuracy and non-interactiveness of measurement etc. Contrary to it, quantum mechanics, as a result of our ambition to understand the microworld, describes our experimental possibilities more realistically: it is impossible to isolate microsystems perfectly; measurement itself influences the measured system etc. For these reasons, quantum mechanics must use the apparatus of mathematical statistics and its the well-known paradoxes are only consequence of our limited experience with consistent statistical description of the world around us.”
Informátor 51 published article: “Rokytka, river of change” by Martin Šťastný and Pavel Hájek with the abstract: “Rokytka, although the length of the flow of only 36 km, is a very interesting river that flows through the beautiful and pure countryside with nature reserves and the highly polluted industrial area once Vysočany. In the vicinity of the river there are many interesting places, both in historical and in terms of science. Mentions the various buildings in the vicinity and is given the results of mineralogical and geochemical studies of sediments of the little river and its tributaries.”
