the data it was found that if the concentration ratios are used instead of the concentration the results are more representative. The information about the pigments was complemented with data received by using X-ray diffraction to determine the structure. The X-ray fluorescence method was also used to compare its results with those of optical emission spectrometry.

Magyar Színképelemző Vándorgyűlés előadásai Eger, 1985, pp. 197—203, (In Hungarian) Illuminations of some codices from the famous library of King Mathias (15th century) were examined before restoration. The greatest problem was the sampling of the illuminations and the selection of the methods giving the most information using the micro samples. The about 0.04 mg mass of samples was first tested by X-ray diffraction method then the Lindemann capillary containing the sample was placed in a graphite electrode and excited by D.C. arc for optical emission spectroscopy. With the joint use of the two methods it was possible to identify the pigments of the illuminations.

The so called levelling plaster supporting the paint layer (the intonaco or the upper layer of the intonaco if it has more than one) of Roman wall paintings was examined by X-ray diffraction. According to the composition four large groups could be identified: plasters containing 1. calcite and a little quartz, 2. calcite, a Utile quartz and dolomite, 3. dolomite, calcite.and a little quartz, 4. dolomite, calcite and a lot of sand. The levelling plaster containing mainly dolomite (3rd group) was frequently utilized in Pannónia. Levelling plaster with a high quartz content is not mentioned in the special literature. From among the fragments examined, those from one of the buildings of the Pannonian capital Aquincum and the bath of the town Gorsium had been painted on such a largely paint-absorbing, non white layer.

The fragments of Roman raw pigments from Baláca (West Hungary) are very valuable pieces for those who study the pigments and wall paintings of the ancient Roman province, Pannónia. These fragments are unique Roman raw pigments excavated up to now in the territory of Hungary. Morphological study of the pigments has given useful infor-
