Archaeological exploration often produces clay daub, a material which has not been fully appreciated so far. There is mainly a lack of its being documented in the context of discovery situations. It becomes mainly a source for archaeobotanical analyses and its evidential value is not used. In connection with discovery circumstances it may help reconstruct the shape of a settlement feature, and in interaction with the other scientific disciplines it may provide information on the course of destruction or on the intensity of heat, or be a basis for the creation of more objective views about static limits of a construction. The given facts, lack of the studies of daub, inevitability to emphasise its meaning for architectonic reconstruction, as well as non-existence of a more integral form of descriptive system, and a lacking database, led the author of the paper to the creation of a unified system of description and comparative database of daub. What is important from methodological aspect is the selection of samples of daub and the creation of a group for a detailed analysis through descriptive system. The first group is selected directly in material depository, with quantitative and basic information and documentation discovery data. The second group is selected in laboratories and makes up a starting group for the final selection. The third group is intended for the detailed analysis in laboratories; it is defined by criteria for the creation of documentation catalogue. Descriptive system reflects specific features of architecture from Neolitic Era and Late Stone Age. The description contains concrete analytical criteria that form and subsequently create a needed comparative database, which becomes a basis for the creation of typology of architectonic construction elements, or a basis for the creation of spatial typological groups of daub. The description itself is always in the process of completions and innovative changes conditioned by the influence of new discovery information. Solutions of several of these problems are objectivised by interdisciplinary exploration and confrontation with the results of experimental archaeology.
