Mosaics guarding the past – commemoration of the battle of Cedynia
1972 was the thousandth anniversary of the battle of Cedynia. The authorities decided to use as information Mieszko's First victory over the German Army of the Margrave Hodo. They decided to create three big mosaics at Cedynia which were built as permanent reminder of the anniversary. Two of them depicted the Battle and the third depicted Cedynia's Coat Of Arms and proto- Slavic vessels. Today they are considered as interesting works of art and a valuable decoration of the area.

Modern glass artefacts from “Shakespeare Theatre” site on Podwale street in Gdańsk
We present glassware from the site of “Shakespeare Theatre” on Podwale Street in Gdańsk. Among the monuments found there are imported products and from the native glassworks, probably from the circle Kartusko- Kościerski. For imports we have categorized wine-cups type Römer, a dekorative glass Stangenglas, Kuttrolf bottle and a wine-glass in the Venetian style. Other products except for typically Polish bell beaker could be both products of Polish factories and brought in from European markets objects. The majority of the collection dates from about the seventeenth and eighteenth century.

Glasses for nuclear waste immobilization
Radioactive waste vitrification is a one of the most effective method of its immobilization. It is based on the incorporation of the waste constituents into the structure of chemically durable glasses. It is one of the few methods which can bind radioactive elements and prevent their spread over a very long period of time. For this purpose a borosilicate or phosphate glasses are used. The paper presents the division, the sources of origin and the basis for radioactive waste management, as well as methods of its immobilization. A review of currently used glasses to the vitrifi cation and the rules applied in the design of their composition is presented.

Influence of temperature and humidity on the spectrophotometric properties of the coated glasses
The article discusses the characteristics and role of the coatings used in construction glazing. The conditions aging which were subjected to antirefl ection coating glass were presented. The light and energy parameters of coating glass that were not exposed to high and low temperature and humidity and coating after aging were determined. The obtained spectrophotometric characteristics of coating glass before and after aging were compared. Elemental composition of the coating surface of the glass before and after aging by scanning microscopy method was determined. The analysis of the results and assess the degree of degradation of coatings after exposure to high and low temperature and humidity was performed.
