- The different forms of presence of Spanish merchants in Rome since the beginning of Early Modern Age: ideas for a debate at European level. Between the 15th and the 16th centuries, due also to the political coverage offered by the empire of Charles V, both Castilians and Catalans succeeded in establishing themselves as the most dynamic merchants in Europe. The control they had over strategic raw materials such as wool, iron and alum and their privileged position gave them easy access to monetary flows in the coastal cities from Flanders to the Mediterranean, where a number Spanish colonies were established. These cities were soon granted with major privileges by local authorities, which fostered the settling of merchants and bankers in certain areas therein. The result, as in the case of Bruges, was the creation of districts protected by exclusive jurisdictional rights or, as in the case of Rome, a random scattering of the new settlers, with no real reference points. In the mid 16th century, in Rome the distribution of places of work and residence followed no national or religious criteria. The complex structure of social relations was thus reflected also in Rome topography.

Abstract A series of scientific methods (X-ray analyses, optical and electron microscopy, Raman spectroscopy and thermal analyses) was used to research the ceramic bodies and glazes of forty vessels from Renaissance Prague. The set of Early Modern Age archaeological glazed ceramics contained tableware, kitchenware and technical ceramics. The main aim was to characterise ceramic materials and glazes used over two centuries. Attention was also paid to the identification of defects and corrosion products of the glazes. The research was conducted with an emphasis on the context of the original use of the ceramic artefacts and the environment of the waste pits from which they were excavated. The archaeological finds include three technical ceramic vessels (a rectifier, a bowl and a jar), which together could have formed a distillation apparatus. Since these vessels represent a rare finding, they were subjected to a detailed investigation. Based on the similarity of ceramic bodies and glazes, it was proved that the three technical ceramic vessels were made in the same workshop and were parts of one distillation apparatus. The results of the performed analyses determined that the studied vessels were manufactured from raw materials with a high content of a plastic component and that the raw materials did not change significantly during the period from the 15th to 18th centuries. The firing temperature of most of the vessels did not exceed 1000 °C. It was proved that all the glazes were medium- or high-lead content glazes and were coloured with ionic pigments.

Any change of the raw material sources for glazes, economically, ecologically motivated, and also from the glaze quality point of view, is conditioned by the molecular formula rationalization and by the variation limits of the molecular formula, respectively. The proper glaze compositions are placed within their limit variation intervals with optimized processing and utilization properties. For this purpose, the rationalization criteria and procedures of molecular formulas are summarized in the present paper, as well as the results referring to their rationalization obtained in the authors� previous work. Thus, one starts from a base of raw materials that are selected, usable and also accessible for the design and producing of the glazes. On these bases the groundwork and the design equation for the glaze recipes are developed, exemplified for a single glaze. For an easy access to results, computer programs are used for an easy access to results.
