In the 19th century the glassmakers were experimenting with old techniques, colors, and new materials. They wanted to reinvent the techniques, developed by Murano glaziers in the time of 14th to 16th centuries. 19th century is also the time of fakes. One of the most prestigious materials was ruby glass. It was made by adding gold into the glass mass. We wanted to find out if the real ruby glass was used on certain artifacts, or there were cheaper surrogates. The difference is not visible by naked eye. The results showed that the glassmakers have used copper compounds. The manufacture of these was much cheaper and thus much wider circles of consumers were able to buy the »objects of prestige«.

Unlike the double-edged »knightly« sword, the messer has received relatively little attention so far. A seemingly plain cutting weapon, it was highly popular throughout the 15th and 16th c. with all classes of the central European society, particularly the peasantry. In-depth analyses of a specimen uncovered in central Slovenia were carried out to provide an accurate overview of its methods of manufacture. In terms of raw materials and workmanship, the messer not merely an inexpensive »peasant« weapon. In quality, it was entirely comparable to cut-and-thrust weapons of the social elite and professional soldiers.

The enormous development and production of plastic materials in the last century resulted in increasing numbers of such kinds of objects. Development of a simple and fast technique to classify different types of plastics could be used in many activities dealing with plastic materials such as packaging of food, sorting of used plastic materials, and also, if technique would be non-destructive, for conservation of plastic artifacts in museum collections, a relatively new field of interest since 1990. In our previous paper we introduced a non-destructive technique for fast identification of unknown plastics based on EDXRF spectrometry, using as a case study some plastic artifacts archived in the Museum in order to show the advantages of the nondestructive identification of plastic material. In order to validate our technique it was necessary to apply for this purpose the comparison of analyses with some of the analytical techniques, which are more suitable and so far rather widely applied in identifying some most common sorts of plastic materials.

Before the First World War considerable efforts were made in Ljubljana to compile the first publicly accessible collection of paintings. Josip Manutani was among the most important persons working on the project. In this article, a collection of drawings by Ladislav Benesch, which Mantuani strived for three years to include into the collection of the Provincial Museum of Carniola, is used as an example of Mantuani's efforts to reconcile the needs and desires of the collection owner with the administrative and financial restrictions emposed by his “employer”, the Provincial Committee of Carniola.
