Progetto "Ambre e materiali vetrosi protostorici della Valle dell'Adige nel quadro delle coeve attestazioni dell'Italia del Nord". Primi risultati sulle ambre
No full textNell’ambito del “Progetto di studio sulle ambre e i materiali vetrosi protostorici della Valle dell’Adige nel quadro delle coeve produzioni dell’Italia del nord” (Ufficio Beni Archeologici di Trento, Sezione di Mineralogia del C.N.R. e Dipartimento di Scienze della Terra dell’Università di Milano), sono in corso una serie di analisi che riguardano oggetti d’ornamento in materiali vetrosi e ambra provenienti della Valle dell’Adige e da altre località italiane. In questa sede vengono presentati i risultati preliminari delle indagini su materiali ritenuti in ambra e provenienti dal Trentino (Vela Valbusa e “torbiera tra Cles e Tuenno”), dall’Emila (Bismantova) e della Puglia (Grotta Manaccora e Coppa Nevigata). Sotto l’aspetto archeologico la relazione verte sul presumibile ruolo della Valle dell’Adige nell’ambito delle cosiddette “vie dell’ambra”. Nello studio dell’ambra la spettroscopia infrarossa è una delle tecniche più diffuse in quanto consente una rapida identificazione del tipo di materiale e, per alcune classi di ambre, anche dell’area di provenienza. Nel presente lavoro sono state effettuate analisi FTIR in trasmissione e in riflettanza diffusa (DRIFT) di campioni standard di ambre, allo scopo di verificare l’attendibilità e il possibile utilizzo di quest’ultima tecnica d’indagine per la creazione di un database che risulti confrontabile con gli studi FTIR già presenti in letteratura. L’utilizzo dell’analisi DRIFT presenta alcuni notevoli vantaggi quali: analisi microdisturttive, rapidità nella preparazione del campione e minor problema di assorbimenti di umidità. I reperti, studiati con DRIFT, si sono rivelati quasi sempre costituiti da Succinite, tranne due campioni d’ambra di diversa origine (ancora incognita) quali il vago tipo “Tirinto” di Bismantova e il frammento di Coppa Nevigata. Particolare il caso del reperto di Vela Valbusa, sempre considerato d’ambra, che in realtà è Lignite
Archaeological excavation at Pletz von Mozze, Luserna, Trentino, Italy. A case study for assessment of late bronze age metallurgical activities
No full textIn the last rwo years (2005-2006). the Archaeological Heritage Department of the Autonomous Province of Trento has started extensive archaeological investigations at a site called Pletz von
Mezze. Unlike previous exploratory surveys. the research carried out involved extensive investigation, allowing recognition of the effective stratigraphic extent of the site and a large area dedicated to prehistoric metallurgical activities has been identified. The Luserna archaeometallurgical site may represent a case study for a Late Bronze Age smelting site. It is not directly related to the presence of ore nearby. Nonetheless the site shows extensive evidence of smelting activities and has been therefore selected as a test site. providing for close
collaboration between archaeologists and archaeometallurgists during excavation. in an attempt to dynamically exchange data, analytical results and experience aud to allow full assessment of ancient metallurgical activities

Protohistoric vitreous materials of Italy: From early faience to Final Bronze Age glasses
No full textVitreous materials were known in the Near.East and Egypt from the 4th millennium BC; faience became common during the 3rdll)illennium from the dynastic time(Aspinall et al. 1912, 27), whereas the mass-production of glass started in the 2nd millennium BC (Henderson 2000, 52). Investigations of Near Eastern samples have shown the presence of'high magnesium glasses (IDv[G) frem the 19th century Bç at 'Ain 'Abata (Jordan) and Tel Dan (Israel); simìlar glass composition were found in materìals from more recent sites, lik:eNuzi (Iraq), Ulu Burun (Turkey), Tell Al-Rimah (Iraq), as summarized by Henderson (Henderson 2000, 54-9). The early Egyptian glasses are of the HMG type and during the 15-1 4th centuries B'C the Egyptian production includes copper blue and cebalt blue frits, glasses and faience (Tite and Shortland 2Q03). The earliest materials indicating the use ofNa-rieh rninerals as the alkali source in low magnesium glasses (LMG) glass production are 13-12th centuries BC glasses from Pella (Jordan). Other early LMG glassés are from Tell Brak (Syria) and Crete. The pieture of Bronze Age vitreous material production in the Aegean area is therefore rather complex. A separate class of glasses having mixed alkali chemical composition (LMHK, Iow magnesium high potassium) has been defined formost Europeanmaterials dated to the late 2nç millennìum BC (Henderson2000-, 54-9). The ltalian samples studied in the present work were selected according to theirtypologyand age, for appropriate comparison with coeval samples from the Eastern Mediterranean area
Gli impasti ceramici di alcuni insediamenti protostorici del territorio polesano
No full textWe present the preliminary data from the results of a research funded by CPSSAE grant (Rovigo) regarding thc ceramic ecology and technology of Iour
settlements (Frattesina di Fratta Polesine, Mariconc!a di Melara, S. Martino di
Vanezze and Larda di Gavello) situated in the uppcr and middle Polesine area.
As regards sourcing and produetion, raw materials and final objccts can be considered
loea1 (except probably for a wheel-rnade sherd from Frattesina), while
from a teehnological point of view we can generally assert that the ceramic production
at these sites is very similar
Frattesina – fase tre: Archeologia ed Archeometria della produzione ceramica
No full textThe important settlement 01 Frattesina di Fratta Polesine (Rovigo) has been investigated through systematic surveys and stratigraphic
excavations during the period 1966-1989. According to Ihe excavalion data and the typological study 01 the cerarnics, we
can reliably assume that the settlement was inhabited since the end 01 Late Sronze Age (phase 1) till the beginning 01 lron Age
(phase 3). During this last phase the local ceramic production is characterized by the use 01 different ceramic pastes, as identili
ed by macroscopic visual estimation. The need to substantiate the empyrical classilication on physico-chemical ground has
prompted an archaeometric study by optical microscopy (OM) observation 01 thin sections, and by X-ray powder diffraction
(XRPD) analysis. The pastes 01 archaeological relevance have been divided into 5 classes (A-F), recognized through the typological
analysis 01 46 pottery sherds, 4 pieces 01 "concetti", and 1 dislinct wheel-made sherd. Ali the investigated pottery samples
were made by mixing local carbonatic clays with different tempers, mostly grog, but also sand-shells mixtures (paste S), vegetables
and straw, and in one case, a very peculiar sand 01 metamorphic origin (paste C). Grog is present in pastes having different
grain-size, the size 01 the temper inclusions being related to Ihe thickness 01 Ihe pot walls. The liring was carried out in variable
atmosphere conditions and/or differenl times, the colour 01 the sherds being relaled lo the linal degree 01 oxidation 01 the paste.
The maximum temperature 01 firing was in the range 60Q-8QQoC. There seems to be a correlation between paste type and pot
shape: Paste E is the mosl diffused and it was used for several pot types, paste A is associated to open shaped pots like bowls
or line pots, paste S is associated to dolia and 100m weights ("taralli"), paste C is associated to open and closed shaped pots,
and paste F is conlined to andiron ("tronchi di piramide") 01 uncertain use. The wbeel-made sherd has different mineralogy and is
assumed lo be imported.
The archaeometric and ethnographic results contribute to piace the ceramic production 01 Fraltesina at a level between the
household and the workshop industries. Significant archaeological similitudes are present with other Sronze Age settle- ; ments 01 the Po Valley, specilically Ihose in the Valli Grandi Veronesi and in the Modena areas
Le ambre delle necropoli di Olmo di Nogara e Scalvinetto (VR)
No full textThe results of a preliminary archaeometric study of amber beads,
including one sp acer bead, from the necropolises of Olmo di Nogara and Scalvinetto
(Verona) are presented. The materials were selected on the basis of typology
and chronology, dated between advanced Middle Bronze Age 1 and Recent
Bronze Age 2 (Olmo) and between MBA3 and RBA2 (Scalvinetto). All samples
are succinite. New data and considerations are emerging on an Adriatic-Adige
Valley amber route in the light of the recent Bernstdorf (Bavaria) findings, for
which an Aegean workmanship is postulated
