Archaeological investigations were conducted at the site in 2002–2003 and 2008–2010. The aim of this paper is to explore the social and trade contacts and networks the rural inhabitants of Gubbacka had within the Baltic Sea region. In order to examine how these relationships are reflected in the ceramic materials from the site, redware sherds were sampled for micro-structural and compositional characterization by a scanning electron microscope with an energy dispersive spectrometer (SEM-EDS) to study their provenance and technological properties. In addition, redwares from a nearby site Mankby and Tallinn were included in this study as regional and inter-regional parallels to examine possible shared origins of the pots and technological applications in redware manufacture. Redware is a very common archaeological find material in late medieval contexts, but rather difficult to investigate: the products ...

Archaeological investigations were conducted at the site in 2002–03 and 2008–10. The aim of this paper is to explore the social and trade contacts and networks the rural inhabitants of Gubbacka had within the Baltic Sea region. In order to examine how these relationships are reflected in the ceramic materials from the site, redware sherds were sampled for micro-structural and compositional characterisation by a scanning electron microscope with an x-ray micro-analyser (FESEM-EDX) to study their provenance and technological properties. In addition, redwares from a nearby site Mankby and Tallinn were included in this study as regional and inter-regional parallels to examine possible shared origins of the pots and technological applications in redware manufacture. Redware is a very common archaeological find material in Medieval contexts, but rather difficult to investigate: the products of the different North European manufacturing centres are practically impossible to distinguish with the naked eye, and even the dating of redware finds is problematic. Hence, this study aims to offer new perspectives for the study of redwares, their technologies and distribution networks in the Northern Europe.

Redware pots first arrived in this region as Scandinavian and Continental imports, and their local manufacture was established in the 15th-16th centuries. We aimed to chemically characterize ceramic and glaze recipes, distinguish between local and imported redware pots at the sites, and to examine glaze preparation and application practices used. Altogether 34 sherds of ceramic artefacts from three hamlet sites in the Helsinki region (Gubbacka, Mankby and Mårtensby), and the towns of Turku and Tallinn were geochemically and microstructurally analysed by energy-dispersive X-ray fluorescence spectrometry (ED-XRF) and scanning electron microscopy with energy-dispersive spectrometry (SEM-EDS). The majority of the analysed pots were made of clay originating from the Gulf of Finland region, produced at least in Turku and highly likely in Tallinn. Redware was also exchanged between these trading areas. High-lead-content (PbO < 67 wt%) glazes, sometimes opacified with tin, were applied as lead-oxide itself or as a lead-oxide-plus-sand mixture on unfired non-calcareous, iron-rich ceramic bodies. This glazing technology to produce impermeable pots was achievable at relatively low temperatures and cost, hence it was commonly adopted by ceramic producers in the North, and stayed in vogue for centuries. Redware pots from different sources appear visually and morphologically related, yet microstructural inspection reveals varied glazing technologies.

Redan i kring tjugo års tid har det organiserats publika utgrävningar i Finland, men angående deras roll i den finska arkeologin har det inte diskuterats i någon större utsträckning. Gemensamma riktlinjer för de publika utgrävningsprojektens praktiska aspekter har hittills saknats, inte heller har det funderats vidare kring de etiska frågorna som berör särskilt publika utgrävningar. Dessa ärenden behandlades i seminarier som arrangerades i Tammerfors och Åbo åren 2018 och 2019, därtill utfördes en enkätförfrågan till organisatörer av publika utgrävningar. Utgående från seminariediskussionerna och enkätsvaren sammanställs i denna artikel hurudan praxis som visat sig fungerande vid planering och genomförande av publika utgrävningsprojekt.
