The paper focuses on an innovative bilingual multimedia tool designed within the research project funded by the Portuguese Foundation for Science and Technology (FCT) – Gilt-Teller, an interdisciplinary multiscale study of gilding techniques and materials in Portugal, 1500- 1800. The tool was designed with the help of the company Take the Wind Lda. (Coimbra) and is based on an online platform (www.gilt-teller.pt). It has different components, from documents of general description of the project, its team and outcomes in terms of publica-tions and conference presentation or workshop organization to the historical background of the project and short characterization of the main stylistic époques considered under study. The three innovative components are: the bilingual glossary on gilding materials and techniques (http://www.gilt-teller....
Secondary School André de Gouveia (ESAG) is frequently associated to Liceu de Évora from which it inherited the historical and cultural background. Lyceu Nacional d’Évora was established in 1841 after the educational reform of Passos Manuel and was set at Colégio do Espírito Santo, in Évora, until 1979. During that period, a physics and chemistry laboratory was created and developed at the Liceu and it was enriched with brand new scientific objects and small equipment to be used in classes, especially in teaching demonstrations. Crosschecking the information from the records kept at the library of ESAG, sales catalogues and teaching books from that period and information from other sources, it was possible to find out, in several cases, who the seller or the manufacturer of the object was and its function in an experimental design at t...

A dispute among the best five painters-gilders of Evora, for two of the most important contracts regarding the gilding of the altarpieces, gave rise to an extensive and detailed documentation on the technique, materials and prices used in 1729. The rivalry between the master Filipe de Santiago, responsible for the gilding of the whole set of the Church of Mercy (Igreja da Misericórdia de Évora), and the team led by Manuel da Maia, responsible for gilding the main altar of the Convent Church of Scala Coeli’s (Igreja do Convento de Scala Coeli, Cartuxa), forced the commissioners to redraft contracts with unusual rigor since both did not accept the possibility to be examined by the opponent. Physical-chemical charac-terization of the gilding and polychrome layers of samples from both altarpieces, performed within the GILT-Teller project (...
The paper proposes a novel, integrated approach to the identification and quantification of the organic binders, mainly proteinaceous, as the “invisible” component of polychrome layers in artifacts belonging to movable and immovable cultural heritage. The analytical methodology discussed here will demonstrate the significance and efficiency of biochemical assays for the detection of organic binders and how these tests can improve/complement the already existing techniques, while considering also the costs and time of analysis that commonly limit their application in the current laboratory practice for artworks diagnosis.
Adherent deposits are very aggressive towards ancient heritage paintings since they affect the varnish and
the painting’s layers, sometimes reaching the preparative layers. The biggest problem to the restorer is
their removal without affecting the patina, the transparent varnish (well preserved) and fine colour glazes
made during painting. Therefore, their removal requires preliminary cleaning tests that allow the optimization
of the cleaning system composition that is going to be used. The study was focused on organic
natural systems, as colourless supernatants, some of them used during ages, but insufficiently studied.
The paper presents an evaluation of the effectiveness of cleaning varnished icons of the nineteenth century,
with complex conservation cases using supernatants derived from aqueous dispersions extracted
from vegetables...
A arte da talha dourada em Portugal ganhou a sua mais rica expressão durante a época barroca devido ao desenvolvimento das técnicas de produção e ao uso do ouro em folha.O presente trabalho propõe um estudo complementar e comparativo de dois complexos importantes da talha respectivamente em Lisboa, na Igreja de São Alberto, integrada no circuito de visitas do Museu Nacional de Arte Antiga, e no distrito de Santarém, na Igreja de Vale de Figueira. Os dois complexos albergam decoração em talha dourada do séculoXVIII, estudados através de uma abordagem inter-disciplinar, em que os dados analíticos(microscopia óptica, teste de coloração fluorescente, FRX, MEV-EDX, microtomografia computadorizada, FTIR, Matrix-Assisted Laser Desorption/Ionisation-Time of Flight MassSpectrometry) complementam os dados históricos.
O artigo apresenta um estudo interdisciplinar e multi-tecnico dos materiais e das tecnicas de douramento em varios retabulos Portugueses da epoca Barreca, desenvolvido durante um projecto de investigac;ao financiado pela Fundac;ao para Ciencia e Tecnologia em Portugal (PTDC/EAT-EAT/116700/2010). Foram usadas tecnicas microsc6picas,em conjunto com difracc;ao de raios X, microtomografia computadorizada de raios X, espectroscopias de microFTIR e microRaman para caracterizar a estrutura estratigrafica de 49 amostras provenientes de 7 retabulos das areas de Lisboa/ Cascais e de Santarem. A investigac;ao pretende ser tambem um estudo comparative entre materiais e tecnicas de douramento utilizados em retabulos do mesmo perfodo hist6rico, mas provenientes de duas areas geograficas diferentes.
