Introduction
My current project is the archaeometric study of several glass collections found in Portuguese territory. With the determination of the glass objects chemical composition (major, minor and trace elements, including Rare Earth elements) we aim to determine the glass provenance.

Article
The present work aims to study the glasses commonly named crystal glass produced in Portuguese factories from the 18th to the 20th centuries through their arcana or batch books. Recipes for colourless crystal glasses were selected, analysed and reproduced in the laboratory. Five recipes were chosen from the Marinha Grande arcanum, five recipes from...

A set of 14 glass fragments and production remains dated to the 16th and 17th centuries was collected during rescue archaeological works conducted in Granada, Spain, and was characterised by µ-PIXE. This preliminary study constitutes the first analytical approach to glass manufacturing remains from a Spanish production dated to the early-modern per...

Portuguese archaeological excavations dated to the 17th century onwards are extremely rich in glass artefacts, with this being a reality from the north to the south of the territory. Contrasting with this reality, no glass production locations from this period have been discovered or excavated so far, which makes the provenance attribution a challe...

Os vidros millefiori (termo italiano que significa mil flores), são característicos por serem decorados com finas fatias de canas de vidro que, geralmente, têm uma decoração concêntrica visível em secção transversal. Embora sejam considerados artefactos muito raros, estes vidros são dos mais emblemáticos da produção Veneziana do Renascimento. Além...

Among the Santa Clara-a-Velha Monastery finds, one of the largest archaeological glass assemblages unearthed so far in Portugal dated to the early modern period, a blue fragment decorated with enamels and depicting a triumphal procession scene stood out. In this paper, the result of the study performed to this small fragment related to the occupati...

The Italian word millefiori literally means “thousand flowers” and encompasses glass objects whose surface is decorated with multi-coloured slices of glass canes, usually having concentric patterns. The use of canes is first related to mosaic glass technique, one of the most ancient glass working techniques. During the Renaissance, Venetian glassma...

Glass crystal models arrived in Portugal around the late 19th century, when high schools, universities, and polytechnics were gradually provided with teaching collections to support science education. Therefore, they are an important material evidence of teaching methodologies of mineral and geology science in the 20th century. The Passos Manuel hi...

Epoxy resins are widely used in glass and ceramics conservation. Some studies have been done in order to explore the natural and accelerated ageing of these resins. The most used analytical techniques to characterize the epoxy resins and their ageing have been Fourier transform infrared spectroscopy (FTIR), UV-Vis spectroscopy and tensile strength...

This paper presents the study of eighteen samples of colourless glass dated to the Roman period (1st to 3rd centuries C.E.) and that were unearthed in Zadar, Croatia. In this exploratory research, the chemical composition of the glass, which was determined by μ-PIXE, was divided into two main groups based on the alkali and alkali-earth contents: gl...

Among several glass assemblages excavated in the Portuguese territory it is possible to come across a recurrent shape, derived from the traditional dried gourd bottle. This shape was only scarcely identified in other European contexts. For this reason ten gourd shaped bottles were selected from two archaeological assemblages (Santa Clara-a-Velha mo...

This work is part of a PhD project which intends combine the technological study of two glass decorative techniques (pick-up and filigrana) that were very popular in the 16th and 17th centuries, with an analytical approach using a wide range of methodologies across disciplines. It will help to better understand the evolution of these decorative tec...

The archaeometric study of a group of colourless glass fragments recovered from two archaeological excavations performed in Lisbon, Portugal is here reported. The archaeological interventions were performed at Rua do Arsenal (LRA), where the ruins of the Côrte-Real Palace were partially discovered, and at the Roman Theatre Museum (LTR), where the r...

Two sets of wine bottles dated between the end of the 17th and the 19th centuries were characterized by means of μ-PIXE (major and minor elements) and LA–ICP–MS (trace and REE elements). The fragmented wine bottles were recovered from two archaeological contexts in Lisbon and reach a total of 79 fragments. One of the archaeological bottle sets come...

The present contribution addresses the study of more than 150 glass fragments decorated with filigrana technique coming from four archaeological excavations in Portugal: Santa Clara-a-Velha Monastery in Coimbra, Santana Convent and Largo do Chafariz de Dentro in Lisbon, and São João de Tarouca Monastery in Lamego. The fragments show a wide use of d...
Conference Paper
A group of late medieval and early modern glass fragments from an archaeological excavation that took place at Avenida Miguel Fernandes in Beja, a town located in the South of Portugal, was chemically characterised by means of PIXE, micro-EDXRF and UV-Vis absorption spectroscopy. PIXE and micro-EDXRF analysis enabled the determination of the chemic...

All the glasses were found to be of soda-­‐lime-­‐silica type. The relatively high amounts of K 2 O, MgO , P 2 O 5 and the presence of chlorine suggest the use of coastal plants as the source of alkali. µ-­‐PIXE analysis also allowed to distinguish three groups regarding the alumina contents where it was possible to identify a group with low alumin...

Organic pollutants such as formic acid , acetic acid and formaldehyde released by some materials (mainly wood) used for storage and display can play an important role on the alteration of the glass structure due to the alkali leaching process. It as been determined that formic acid when present inside storage or display cabinets is the one that aff...

Project
This project focusses on the production of glass in Portugal between the 18 th and the 20 th century with the aim of assessing the best procedures to be adopted in the conservation of this legacy. During the considered period, the world underwent great changes, namely in the fields of science and technology. Glass industry also went through a major industrial development in Europe, which entailed a better control of the raw materials used in glassmaking, improving glass quality. This project aims at studying the evolution of the raw materials employed in glass production, as well as the production techniques used to obtain new glass (coloured and colourless) in Portugal. This investigation will be made through the study of a group of recipe books that belonged to relevant personalities in the Portuguese glass industry and the use of an archaeometric approach to various glass assemblages coeval to the glass recipes mentioned above.
Project
This project will advance knowledge of the technological development, distribution and use of two decoration glass technics: filigree and pick-up decoration from the 16th and 17th centuries. It aims at establishing patterns for the evolution of the decoration techniques over the years, by analysing glass fragments found in Portuguese archaeological contexts. This new knowledge will be evaluated in a broader cultural framework, considering peoples’ tastes (regarding decoration motives and colour changes) and also the trade flow between Portugal and other European countries. It will also contribute to better understand the material deterioration, trying to distinguish if the crizzling and cracks are due to material incompatibility or to burial conditions. Reproductions of this decorations based on historical written sources will support the study of the corrosion processes of these heterogeneous glass objects. A multi-analytical approach will be carried out based on Optical Microscopy, UV-VIS Reflectance Spectroscopy, Proton Induced X-ray Emission, Raman Microscopy and Scanning Electron Microscopy.
