Cistercian Horizons - collected essays

Mediaeval blue colour has long been the subject of several histories and stories concerning its meanings and sources, especially the use of ultramarine and the introduction/transition to azurite in the art history painting’s production. Being the most expensive blue pigment during the mediaeval to renascence period, ultramarine is said to have been selectively used for the most important representations of the ...

“The study of the biographical trajectory of a Portuguese 12th c. illuminated m...

Medieval illuminated manuscripts are among the best testimonies of the life of medieval scriptoria. This work traces the biographical trajectory of a Lectionary according to the Cistercian rite – the Alc. 433 - through the liturgical studies and the material characterisation of its painted illuminations, with the aim of obtaining the chronological timeline of the use of colour materials in the Portuguese script...

Characterization of Tableware from Fábrica de Loiça de Sacavém—Linking Analytic...

Fábrica de Loiça de Sacavém (ca. 1858–1994) was among the first to produce white earthenware in Portugal, becoming one of the country’s leading ceramic manufacturers during the late 19th to early 20th centuries. Research on white earthenware has accompanied the growing interest in post-industrial archaeology but is still poorly explored compared to more ancient ceramic productions. This study focused on the cer...

Comparative assessment of two portable Raman spectrometers for the characterisa...

This paper explores the use of portable Raman instruments to characterise nat- ural dye lakes in paint mixtures, as an alternative approach to other Raman techniques (e.g. SERS). Raman spectroscopy has indeed been used extensively to study natural dyes as pure substances or as artistic pigments (dye lakes). However, the examination of these compounds with Raman spectroscopy is particularly challenging because o...

Located at Caxarias (Ourém, Portugal), this manufacturer produced diverse ceramic-based architectural materials, from common clay bricks to sophisticated modernist azulejos. Recently members of the family of the former Tijomel Manufacture owners retrieved a collection of 33 raw materials, mostly...

On the use of hand-held X-ray fluorescence spectroscopy coupled to Monte Carlo ...

This paper presents the application of an established XRF-MC (X-ray fluorescence-Monte Carlo) protocol to evaluate for the first time the thickness of pictorial layers in illuminated manuscripts. A previously investigated, sixteenth-century book printed in Paris (BPE, Inc. 438) was chosen as the case study: multiple analysis spots were scanned in selected areas (painted and unpainted) with p-XRF (hand-held XRF)...
