The project Saving Oseberg is funded by the Norwegian State with the aim to preserve the Viking Age wooden objects from the Oseberg burial mound. They were excavated in 1904 near Tønsberg, Norway, and many have been treated in the past with alum salts (KAl(SO4)2·12H2O). Alum was widely used during the early 1900s as a treatment for archaeological w...
This paper aims to expand our understanding of the processes involved in the production of the artificial pigment Egyptian blue through the scientific examination of pigments found in the first century BCE workshop of the Greek island of Kos. There, 136 Egyptian blue pellets were brought to light, including successfully produced pellets, as well as...
The presented research examines 17th century distemper paint from the polychrome
wooden interiors of two Norwegian stave churches: Eidsborg and Heddal. For the first time, the inorganic and organic components of specimens from Eidsborg and Heddal were identified using X-ray Diffraction (XRD), Environmental Scanning Electron Microscopy (ESEM)—Energy...
Lignins are valuable renewable resources for the potential production of a large array of biofuels, aromatic chemicals and biopolymers. Yet native and industrial lignins are complex, highly branched and heterogenous macromolecules, properties that have to date often undermined their use as starting materials in lignin valorisation strategies. Relia...
Viking Age archaeological wooden objects from the Oseberg find have undergone extensive chemical deterioration due to the original conservation treatment, based on alum salts (KAl(SO4)2·12H2O), done in the early 1900s. Today, the artefacts are highly acidic (pH ≤ 2), fragile and the wood has almost completely lost its structural integrity. This stu...
Ochres are natural deposits particularly enriched in iron oxides and hydroxides giving them their typical colours
spanning from bright red to yellow or brown. For this reason, they have been widely exploited over millennia for
artistic purposes, becoming among the most known pigments.
A series of 16 iron-based powder pigments including both commerc...
The structural properties of geopolymers based on locally available volcanic feedstocks were here investigated in the optics of the development of sustainable non-structural building materials. Geopolymer binders and mortars based on two volcanic pyroclastic residues from Mt. Etna (ejected ash and a paleosoil, named “ghiara”) were studied to assess...
The aim of this paper is to classify the significance of a set of treatment evaluation procedures and parameters in forming educated decisions on how to treat or retreat archaeological wooden objects. We did this as part of our research with the Saving Oseberg project on finding an appropriate retreating scheme for the alum-treated Oseberg wooden c...
The sampling procedure is a necessary step in the study of materials of cultural heritage, including historical textiles. In particular, the characterization of dyes often results in samples which are destroyed or irremediably damaged during the procedure. Fortunately, technological developments currently allow researchers to obtain detailed inform...
The investigation of dyes in historic textiles is a widely documented field and, due to the nature of such compounds, many analytical methods can be successfully employed. Most of the materials encountered in the field of cultural heritage can be analysed with non-invasive and micro-invasive techniques. This chapter presents an overview of the non-...

Volcanic pyroclastic residues from Mt. Etna have been recently used to produce alkali activated materials to be employed in the restoration of the ancient buildings of the Etnean area. With the aim of preliminarily testing the durability of these products, binders and mortars have been exposed outside for six months. The characterization was achiev...
This work is part of a larger study, which aims to use soda lignin from straw as the starting point for a non-aqueous consolidant for highly degraded archaeological wood from the Oseberg collection. This wood was treated with alum salts in the early 1900s, is actively degrading and exists in varying states of preservation. Non-aqueous consolidants...
There is currently a pressing need for the development of novel bioinspired consolidants for waterlogged, archaeological wood. Bioinspired materials possess many advantages, such as biocompatibility and sustainability, which makes them ideal to use in this capacity. Based on this, a polyhydroxylated monomer was synthesised from α-pinene, a sustaina...

Nanolime dispersed in 2-propanol was extensively used for the consolidation of wall paintings. The knowledge of the advances of this methodology dealing with all the possible effects associated with the nanolime new material in conservation is fundamental to assess and improve the technique. In this paper, four different dispersions of Ca(OH)2 nano...
