你必须去柏林

正我要一个人搭车去柏林然后回来,我一直没去做,不仅是因为我害怕独自一人穿越三四个国家,也担心因为语言不通会遇到各种措手不及的情况。也许,我会拦不到车,最后坐车回来;也许,我会遇到坏人……不过我现在决定去做了,so what!     

A preliminary study of ceramic pastes in the copper age pottery production of the Rome area

This paper presents the preliminary results of an analytical study on domestic pottery samples originating from the Copper Age sites of Casetta Mistici, Tor Pagnotta, Osteria del Curato-Via Cinquefrondi, Torre della Chiesaccia and Valle dei Morti, all of which are located in the Rome area (Latium, Italy). The aim of this research is to define the compositional features of the ceramic pastes and to reconstruct the main technological choices characterising pottery production in these contexts. The importance of these archaeological sites lies in their geographic position, being located in an area bounded by the Tiber and Aniene rivers and the Colli Albani volcano, and in their stratigraphic sequence, spanning from the mid-fourth to the end of the third millennium bc. This research, based on a petrographic and chemical investigation of pottery samples, led to the distinction of eight petrographic groups that reflect specific choices in pottery production. Moreover, the analytical results provide indications about the prehistoric pottery production of the Rome area in relation to the ceramic recipes used, the pastes that were obtained and their sourcing areas.     

Iron Age Ferrous Hammerheads from Britain

There are more than thirty iron hammerheads known from the pre-Roman Iron Age in Britain, the majority of which are assigned to the first centuries BC and AD. They include specialised tools, such as set hammers and a swage sledge-hammer which are blacksmiths' tools. The hand-hammers are more numerous and many of these are probably also metalworkers' tools. Fourteen have been examined by metallography showing that at least ten are quench hardened at one or both faces and some may have been tempered.
