The study presents 175 artefacts from the settlement center in Gniezno – beads and rings. The materials come from settlement levels from around the mid-10th to the 13th centuries. The latest chronological findings based on 14C dating have made it possible to refine the dating, especially of the early settlement levels of the stronghold, where the vast majority of glass artefacts come from. Threeba sic groups of beads have been distinguished based on the technique of their production – beads made of a drawing a tube, the technique of winding a glass strip, as well as casting and sintering. The results of 7 physico-chemical analyzes of the glass composition (performed with the X-Ray Fluorescence, XRF method) are presented. Physicochemical analyzes of the chemical composition of the tested beads made it possible to determine the technological group and the type of glass. An attempt was made to explain the origin of the starting material (glass) for jewelery. A comparative analysis made it possible to indicate in a general manner possible manufacturers and to outline the likely directions of the influx of these glass ornaments to Gniezno.

Continuous casting process is used for the solidification of molten steel into semi-finished shapes. Due to lack of reliable sensors online, manual monitoring was often essential to cooling control, which was time consuming and inefficient. This paper proposes an approach to automatically monitor high-temperature casting strand based on radiation thermometry, with the help of CCD (charge coupled device) camera and digital image processing technology. The bicolorimetric temperature measurement method is introduced in detail, as well as the working principle of CCD. Programs developed by Visual C++ 6.0 complete the acquisition, processing, calculation and visualization of casting strand image data. Besides, some experiment of temperature test was carried out for bloom casting (section size of 260 mm×300 mm) in a domestic steel plant so as to verify the monitoring model. Consequently, the purpose for monitoring casting strand is achieved, which is beneficial to cooling control in the process of continuous casting.
