Achaeometrical Research in Hungary II., 1988

BIBLIOGRAPHY - SUMMARIES - ANALYSES

Magdalensberg (Austria) and from other places (recently in Hungary, Slovenia, Croatia) of the Roman province Pannónia. The following types and workshops were represented among the amphorae studied: Dressel 6B (dominant type), Dressel 2-4, Dressel 5, Dressel 6A, Dressel 7-11, Portorecanati and Schörgendorfer 558. Both the clasts and the matrix (groundmass) of the pottery were characterized. The data were summarized in several tables. The following clasts of amphorae were determined by polarizing microscope: Minerals quartz, K-feldspars (orthoclase, sanidine and few microcline), plagioclase, micas (biotite, muscovite), chlorite, opaque minerals, pyroxene (few), amphibole (few), accessories (zircon, rutile, titanite, tourmaline, apatite, garnet, epidote, zoisite-clinozoisite, kyanite). Rock fragments - quartzite, chert, siliceous shale, sandstone, mudstone, shale, sparite, micrite, phyllite, mica-schist, granite, volcanite, volcanic glass. Fossils - calcitic(foraminifera, shell fragments), opalic- (spicula) and quartzitic- (radiolaria) fossils. The groundmass of the amphorae consisted of quartz, K-feldspar, plagioclase, micas, calcite, gehlenite, pyroxene, amphibole, gypsum, wairakite (determined by X-ray powder diffraction). The analysis of the clasts of the stamped samples made it possible to give the common mineral and rock types for the different workshops (which information can be utilized while handling not stamped fragments). The mineral and rock types, characteristic for different geological environments, could be used for giving information about the geographic position of the workshops. The size and the shape of the clasts and the type and colour of the groundmass gave information about the ancient preparation and burning technology.

X-ray diffraction study of powdered samples of 50 amphora fragments were carried out. The samples were collected from the Amber Route and belonged to the types and workshops as follows: Dressel 2-4 (8 samples), Dressel 5 (2), Dressel 6B (40, from various workshops, with stamps of С Laecanius Bassus, Calvia Crispinilla, with imperial stamps, or without any stamps). 288
