Conversion of a digital camera into a non-contact colorimeter for use in stone cultural heritage: The application case to Spanish granites

In this study, a digital CMOS camera was calibrated for use as a non-contact colorimeter for measuring the color of granite artworks. The low chroma values of the granite, which yield similar stimulation of the three color channels of the camera, proved to be the most challenging aspect of the task. The appropriate parameters for converting the device-dependent RGB color space into a device-independent color space were established. For this purpose, the color of a large number of Munsell samples (corresponding to the previously defined color gamut of granite) was measured with a digital camera and with a spectrophotometer (reference instrument). The color data were then compared using the CIELAB color formulae. The best correlations between measurements were obtained when the camera works to 10-bits and the spectrophotometric measures in SCI mode. Finally, the calibrated instrument was used successfully to measure the color of six commercial varieties of Spanish granite.

Aspectos constructivos y decorativos de la villa romana de Puente de la Olmilla (Albaladejo, Ciudad Real)

El esquema constructivo de esta villa responde al modelo típico romano: una serie de estancias distribuidas alrededor de un patio central, que las ilumina y desde el que se accede a ellas mediante los pasillos circundantes, cubiertos con pisos de mosaico, al igual que varias habitaciones (dos de ellas adornadas con mosaicos figurativos). Puente de la Olmilla tenía un pórtico en la fachada, combinación que corresponde a un tipo de construcción poco común en Hispania. Esta villa es un claro testimonio del profundo proceso romanizador sufrido por el medio rural en este territorio. Sin duda, este ámbito de la Meseta Sur tenía para los romanos un carácter estratégico por su privilegiado emplazamiento geográfico dentro de la Península Ibérica y esa fue una de las causas de que lo incluyeran en su red viaria.

La palmera, elemento identitario en el paisaje de huerta del Bajo Segura

La palmera, por sus múltiples aprovechamientos (agrícola, constructivo, ritual e industrial), ha sido tradicionalmente un elemento identitario en el paisaje huertano del Bajo Segura. En las últimas décadas su presencia se ha restringido, al perder las funciones que antaño cumplía, a lo que se ha unido la plaga del picudo rojo y la comercialización masiva con fines ornamentales para las nuevas áreas residenciales. El artículo aborda la presencia de esta especie en el territorio desde diversas visiones y en diferentes épocas: la estética de la literatura de viajes, la productiva de los tratados científicos o la emocional de las obras de creación.

Artefatos funerários como fontes para a história de ofícios urbanos artesanais

Este artigo descreve o uso de artefatos funerários na reconstituição histórica do processo de trabalho em marmorarias instaladas no município de São Carlos (São Paulo, Brasil), no período 1890-1950. Observação direta e registro fotográfico de artefatos funerários, exame de ferramentas de trabalho e utilização de fontes orais permitiram a reconstituição do processo de trabalho. A composição química de fragmentos de artefatos funerários foi determinada por Difração de Raios X e Microscopia Eletrônica de Varredura, evidenciando matérias-primas e sua combinação e uso no processo de trabalho. Considerando-se as etapas produtivas da indústria de rochas ornamentais (extração, serragem e beneficiamento final), os artefatos funerários indicam que as marmorarias inseriam-se na etapa de beneficiamento final. As marmorarias integravam os setores de base técnica artesanal da indústria brasileira, apresentando: baixo grau de concentração de capital e de operários; predomínio da habilidade do ofício especializado; separação pouco nítida entre trabalhadores e instrumentos de trabalho; identificação do trabalhador com o produto. Artefatos de mármore e granito eram destinados a brasileiros de segmentos sociais abastados, durante o início da imigração na cidade de São Carlos (final do século XIX). A partir de 1920, italianos incorporam-se a clientela dos marmoristas, indicando a mobilidade social do imigrante na cidade.

A Coleção de azulejaria antiga da Faculdade de Belas Artes da Universidade de Lisboa : processo de inventário

This thesis presents the process of conducting the inventory of the old tiles collection of the Faculty of Fine Arts, University of Lisbon (FBAUL). This set can be divided into two major groups: the first is integrated in the building, the second consists of a set 2036 loose tiles with a pattern of decorative, ornamental and figuratively, some of which form panels of great value. Due to the existence of a wide variety of unknown provenance tile, stored at random, we feel the need to develop an inventory process, intended to safeguard and preserve these he-ritage objects whose existence was virtually unknown until the beginning of this work. This process continued working methodology started with the identification, photographic survey and labeling, with subsequent filling an inventory sheet. To obtain information about the loose tiles, it was essential to have a previous cleaning the mortar that prevented the reading of existing information in masonry, a process developed with the support of un-dergraduate students. After completion of the above process, we make the assembly of panels existing mostly very fragmented to give some iconographic references. In this process we identified 21 types of patterns belonging to the seventeenth and eighteenth centuries and 30 figurative and orna-mental panels. We realized then interconnections between them and the sets placed in situ around the building, and some of its tiles have been used to fill spaces or gaps. At the same time, we have created the inventory records, diagnosis and intervention, as well as a database for internal consultation - Excel - organized by a filtering system to allow quick search of all the tiles present in FBAUL. Finally, we will show a room to house the collection of loose tiles, making references to the ideal conditions of the outdoor environment and its packaging. Also we propose a very punc-tual removing some tiles embedded in the walls of the building which form part of panels composed of loose tiles, indicating a proposal to replace the other coherent and complete element belonging to the collection, preferably with a standard reason
