“…Many publications on conservation research appear in scientific journals or conference publications. A related topic appeared, for example, in articles such as case studies in stratigraphic studies of historical houses in Alentejo (southern Portugal), studies of color characteristics, and the conditions of using traditional lime painting technology (Gil et al 2007(Gil et al , 2008(Gil et al , 2009.…”

The article presents an analysis of the color evolution of tenement houses in Wroclaw in the 19th and early 20th centuries. Their various colors, confirmed by research, prove the term “Colorful Wroclaw”, appearing in the 1930s the architectural journals. The considerations were supported, i.e., by iconographic material presenting the varied colors of renovated tenement houses in Wroclaw. The aim of this analysis is to show the role of scientific and conservation research in restoring the historical value of buildings. Examples of tenement house restoration projects show the practical application of scientific research to formulate conservation guidelines and organize renovation work. Renovation work also requires traditional and increasingly modern construction techniques. These historical buildings belong to the country’s cultural heritage. They are usually entered into the Monuments Register and are subject to conservation protection. Restoring their former appearance and character is possible thanks to the participation of national and international institutions. It deals with supporting the flow of knowledge and financial resources. The following research methods were used: archival and literature studies, analytical studies of selected conservation techniques and stratigraphic studies of paint coatings, and case studies when discussing renovation projects for selected tenement houses.

“…As Figuras 3 e 4 ilustram, respetivamente, o mostruário de cores para as pinturas das edificações publicado por Luiz Augusto Leitão em 1896 e a relação de preços entre vários tipos de materiais pictóricos disponíveis em 1757, 1880 e 1896 [11][12]22]. Entre os pigmentos citados, são de realçar os ocres, os almagres, os roxos-reis, a terra roxa e o azul ultramarino (ou azul ultramar), que foram dos materiais inorgânicos mais empregues nas pinturas a cal do património edificado português (Figura 1) [1,14,17,19,23]. Do mostruário de Luiz Augusto Leitão constam pigmentos, mas também corantes, ou seja, compostos de origem orgânica, de que são exemplo o anil e uma série de materiais de cor cuja composição química é atualmente incerta (Figura 3).…”

“…Todos os autores, de uma forma geral, são concordantes em relação à composição dos pigmentos aquando da sua descrição. A única variação detetada foi ao nível dos pigmentos roxo-rei e roxo-terra que, identificados em pinturas a cal na região do Alentejo, ainda hoje suscitam algumas dúvidas [23]. Para João Emílio dos Santos Segurado, os dois materiais eram obtidos da calcinação mais ou menos prolongada de ocres amarelos [6].…”

Lime paintings in Treatises and Construction Technical Manuals in Portugal from 1880 to 1931 – An historical review

A review of the lime painting technique is made based on five Treatises and Construction Technical Manuals that were published in Portugal between 1880 and 1930 and were or became a reference in technical and professional education. The goal is to document the history of one of the most popular types of painting in Portuguese Building Heritage until about 1960, whose testimonies still remaining in historic centers should be studied for the purposes of registration and rehabilitation works. This survey enabled to ascertain details of the executants, of the materials and the know-how which are still little known today and to highlight the paradigm shift from what was once considered a type of coarse painting that only gave rudimentary and monotonous tones.

“…The use of "Azul de Aljustrel" pigment is thought to have been an episode lasting only a few years, as no other references are known [35]. Concerning its nature, it is supposed that it might have been a pigment based on copper sulphates or basic copper carbonates existing in the sulphur deposits of the Aljustrel region [36]. In similar deposits in the Spanish IPB, ancient references about the collection of materials in pits for making paint and for medicinal use (probably in Rio Tinto) led Rebollar [37] to consider that these materials were sulphates and melanterite rather than chalcanthite.…”

Mineral Inventory of the Algares 30-Level Adit, Aljustrel Mine, Iberian Pyrite Belt, Portugal

et al. 2020

Mining activity in Algares (Aljustrel Mine, Portuguese sector of the Iberian Pyrite Belt, IPB) stems prior to Roman times. As the orebody is vertical and relatively thin, mining was carried out mainly along underground adits (galleries). Nowadays, the deposit is considered exhausted and the area is being rehabilitated for a different use. The Algares +30 level adit intersects two volcanic units of the IPB Volcano-Sedimentary Complex. The massive sulphide and related stockwork zone are hosted by the Mine Tuff volcanic unit and are exposed in the walls of the gallery, showing intense hydrothermal alteration. Along the mine adit, the geological sequence is affected by strong oxidation and supergene alteration, giving rise to the formation of secondary minerals through the oxidation of the sulphides. The most common minerals found were melanterite (FeSO4·7H2O) and chalcanthite (CuSO4·5H2O), forming essentially massive or crystalline aggregates, ranging from greenish to bluish colours. Melanterite from the walls revealed to be Cu-rich by opposition to that from stalactites/stalagmites formed below the old ore storage silo revealing the low-copper-grade ores exploited underground. The mineralogy of the efflorescent salts was used to ascertain the processes involved in their formation, and moreover, the inventory of minerals is presented, as well as their principal characteristics.
