- Theory vs practice: synthesis of red lead following ancient recipesPublication . Gonçalves, Paula M.; Pires, João; Carvalho, Ana P.; Mendonça, Maria Helena; Cruz, António JoãoThe synthesis of red lead pigment (chemically lead oxide, Pb3O4) was carried out considering different starting lead compounds. The experimental procedure followed was established according to some recipes of ancient painting treatises and the knowledge of the phase transformation of lead oxides. The samples transformation was monitored by X-ray powder diffraction and selected samples were also characterized by scanning electron microscopy. The pure Pb3O4 phase was obtained for the transformation of PbO2 and 2PbCO3·Pb(OH)2. Morphological studies revealed that the material obtained from PbO2 presented the more homogeneous grain size distribution. The transformation of white lead Kremer Pigment resulted in a mixture of Pbr3O4 (major phase) and cerussite (PbCO3), leading to a sample with low crystallinity.
- Sobre um tratado inédito de pintura da primeira metade do século XVII: o 'Breve Tratado de Iluminação', composto por um religioso da Ordem de CristoPublication . Cruz, António João; Monteiro, PatríciaAn anonymous Portuguese manuscript about painting materials and techniques, entitled Breve Tratado de Iluminação, that is, Short Treatise on Illumination, unpublished until now, is presented in detail, as well as its authorship, date, sources, structure and originality. The manuscript, dated from the first half of the 17 th century (after 1618), is a miscellaneous work composed by two main pieces, with the same calligraphy, and varied recipes, with diverse calligraphies, some of them organized around specific subjects. The two main pieces, in a small number of recipes, show the use of Filipe Nunes’ The Art of Painting, a Portuguese treatise published in 1615. In addition, these pieces quote technical procedures employed by both Portuguese and foreigner painters that worked in Portugal, although the sources of this information remain unknown. In relation to the assorted recipes, several were detailed copied from, among others unidentified sources, Nunes’ treatise and Spanish editions of Juan Pérez de Moya (the only work mentioned in the manuscript) and Alessio Piemontese works, both dated from the second half of the 16th century, and others recipes mentioned procedures used by Spanish or French artists. The manuscript, as a whole, seems to be an original work and it is possible that its authors were monks at a Lisbon convent.
- Em busca da origem das cores de 'O Livro de Como se Fazem as Cores': sobre as fontes de um receituário português medieval de materiais e técnicas de pinturaPublication . Cruz, António JoãoO Livro de Como se Fazem as Cores, that is, The Book on How to Make Colours, is a 15th century Portuguese compilation of receipts about painting materials and techniques for which sources and influences were searched. Contrary to the expectations, influences of the Mappae Clavicula were not found, but some similarities were detected between O Livro de Como se Fazem as Cores and Jehan Le Begue treatise’s Experimenta de Coloribus (1431), the H490 Montpellier Manuscript (1460-1480) and, to a lesser degree, thet Bolognese Manuscript also know as Segreti per Colori (first half of the 15i th century). These similarities manifested through the procedures on how to make some pigments, namely mosaic gold and silver blue, and through the names attributed to certain pigments or pigments’ raw materials.

- E-waste handling process from A to Z in PortugalPublication . Cabral, Rui; Moita, Filipa; Vidal, Ricardo; Queiróz e Melo, Filipe; Cristóvão, Hugo; Başarıcı, Samsun M.; Zincir, Ibrahim; Rana, Tohid Ahmed; Marques, Célio Gonçalo; Gestosa da Silva, VascoThe conference “E-waste handling process from A to Z in Portugal”, held in Portugal on May 6 and 13, 2014, and focused on the general aspects in the treatment of electrical and electronic equipment (EEE) at the end of life cycle was carried out under the program EWASTEU - Legal Regulations and Implementations on e-waste in EU. This program had its first edition in 2013 in Yasar University (Izmir, Turkey), with the participation of several higher education institutions in Europe, including the Polytechnic Institute of Tomar (Portugal). The project aims to promote discussion, reflection and awareness about the issues related to the waste from electrical and electronic equipment (WEEE). The conference allowed a clear view of the processes involving the EEE since its entry to the stages of collection, management and recycling. Among the entities involved, we highlight the ANREEE - National Association of Registration of Electrical and Electronic Equipment, ERP Portugal (one of the two managing bodies of WEEE in Portugal), Interecycling (1st Portuguese WEEE recycling company) and RESITEJO – Association of Management and Treatment of Waste in the Middle Tagus. This conference was promoted by the Polytechnic Institute of Tomar, Yasar University and Turkish National Agency
