- Basing on the agreement signed by the Ministry of Culture and Information of the Socialist Republic of Vietnam and the Ministry of Culture and Arts of the Polish People’s Republic, a Polish-Vietnamese conservation mission began in 1980 its activities. Its aim is the protection, preservation and conservation of historic structures left by the Champa tribe on the territory of the present mid-Vietnam. The execution of the works was entrusted to specialists form workshops of monuments conservation. During their a few months stay in 1981 Polish specialists, in cooperation with Vietnamese teams, made a number of architectural recordings and photogrametric measurements, technological investigations and conservation expertises as well as plans for the protection of several structures in the complex of temples in Mi Son, Nha Trang, regions of Qui Nhon and Phan-Rang. They made also constructional stregthenings for one of the towers at Phan-Rang, employing to this end a technique successfully applied in rescue works carried out on the renewal of Lublin. Results of those intensive works will allow the authors to prepare a comprehensive programme for the conservation of the Champa towers which represent the world cultural heritage. According to the hypothesis of French researchers, confirmed by Vietnamese specialists, bricks used in towers were joined together with a special glue obtained, i.a., from the mollusc. Still another hypothesis assumed that the structures were built from dried bricks and then the entire structure was kilned, taking here the advantage of a characteristic arrangement of towers with large portals and oriffices on the top, the construction of which was very similar to ovens used to kiln ceramic materials. The object of the studies made in the Institute of Monuments History and Conservation at the Copernicus University in Toruń was to determine problems connected with a technology of the execution of the ceramic material used to build walls and decor of towers, and to find out a technique of joining the bricks and architectural elements into the whole. In the first stage of the studies samples of the bricks from one of Mi Son’s temple belonging to group С (after Permentier) were analyzed. In the second stage samples taken from the remaining structures are to be examined. The first stage covered also a determination of certain physical and technical properties as well as an analysis of X-ray, thermal and IR spectroscopic difraction. During the studies which were to verify hypotheses of French researchers microchemical tests have been made for the presence of proteins, sugar and oils. Results of the studies allow us to state that samples do not contain organic substances capable of binding the bricks with blue. Interpreting the results of X-ray structural studies the presence of the same minerals as those found in the bricks (i.e. B-quartz and illite) has been found on the surfaces of bricks joining. The conclusion may be hence drawn that the second hypothesis assuming the burning out of the structure as a whole without an earlier thermal treatment of bricks cannot be true either. In the light of the presented initial results of the studies one can assume that the structure was made of kilned bricks joined with a thin layer of clay solution that played the role of building mortar. It is not excluded that some organic substance (e.g. extract from snails) was added to the mortar in order to improve its gluing stregth and then got disintegrated in the kilning process. Still, to fully explain technology of binding ceramic material used in tower temples of the Champa will be possible only after making comprehensive field and laboratory examinations of samples taken from several preserved building complexes.
