Serviços educativos e turismo cultural no museu da tapeçaria de Portalegre Guy Fino

Este projecto faz uma abordagem à nova museologia e ao seu papel no mercado do turismo, com especial enfoque nos serviços educativos dos museus portugueses e na sua relação com o turismo cultural. O estudo do património artístico e cultural do Museu da Tapeçaria 1e Portalegre Guy Fino e da Manufactura de Tapeçarias de Portalegre, bem como a análise crítica dos serviços educativos de museus importantes a nível nacional e internacional, serviram de suporte à realização do projecto de criação de serviços educativos no referido Museu. O projecto tem como principal objectivo qualificar a oferta turístico-cultural que as Tapeçarias de Portalegre representam e está estruturado de forma a poderem ser desenvolvidas actividades em rede com os outros dois museus da cidade, o Museu Municipal e a Casa Museu José Régio. Foram escolhidas, como áreas temáticas, a História, a História da Arte e a Literatura. As actividades propostas para as áreas temáticas, são de três tipos: visitas dinamizadas, visitas-oficina e vistas-jogo, podendo algumas delas ser desenvolvidas on-line, de forma interactiva. Todas as actividades propostas exploram conteúdos programáticos que integram os planos curriculares do 1° Ciclo do Ensino Básico, podendo algumas delas ser desenvolvidas também por alunos do 2° Ciclo e por famílias de diferentes nacionalidades. O projecto constitui um primeiro passo para uma progressiva transformação das Tapeçarias de Portalegre numa atracção âncora do turismo cultural regional, sem perder de vista as suas inquestionáveis potencialidades de se tornar numa atracção de âmbito nacional e internacional. ABSTRACT: This project makes an approach to the new museology and its role on tourist market, with special focus on the educational services in portuguese museums and its relationship with cultural tourism. The investigation about the artistic and cultural patrimony of Guy Fino Museum and the Manufacture, as well as the critic analysis of educational services in important national and international museums, supported the present project of creation of educational services for Guy Fino Museum. The defined main objective of the project is qualifying the touristic and cultural offer represented by the Tapestries of Portalegre. lt is structured in a way that allows activities to be developed in network with other museums in the city: The Municipal Museum and the Museum House of Jose Regio. ln this way, the following areas were chosen: History, History of Arte and Literature. The activities proposed for the themes are three types: dynamic visits, visits - hands on and visits - games, some being developed on-line, in an interactive way. Twelve activities were conceptualized. Ali the proposed activities explore programmed contents that integrate curricular plans of primary school. Some of the activities can also be developed by students of secondary school and families. The translation of the material used should be in a way that they can be used and developed by foreign visitors. The project constitutes a first step for a progressive transformation of the Tapestries of Portalegre in an anchor attraction of the regional cultural tourism, being sure of their unquestionable potentialities to become a national and international attraction.

Development and optimisation of protocols for surface cleaning of cultural heritage metals

The conservation and valorisation of cultural heritage is of fundamental importance for our society, since it is witness to the legacies of human societies. In the case of metallic artefacts, because corrosion is a never-ending problem, the correct strategies for their cleaning and preservation must be chosen. Thus, the aim of this project was the development of protocols for cleaning archaeological copper artefacts by laser and plasma cleaning, since they allow the treatment of artefacts in a controlled and selective manner. Additionally, electrochemical characterisation of the artificial patinas was performed in order to obtain information on the protective properties of the corrosion layers. Reference copper samples with different artificial corrosion layers were used to evaluate the tested parameters. Laser cleaning tests resulted in partial removal of the corrosion products, but the lasermaterial interactions resulted in melting of the desired corrosion layers. The main obstacle for this process is that the materials that must be preserved show lower ablation thresholds than the undesired layers, which makes the proper elimination of dangerous corrosion products very difficult without damaging the artefacts. Different protocols should be developed for different patinas, and real artefacts should be characterised previous to any treatment to determine the best course of action. Low pressure hydrogen plasma cleaning treatments were performed on two kinds of patinas. In both cases the corrosion layers were partially removed. The total removal of the undesired corrosion products can probably be achieved by increasing the treatment time or applied power, or increasing the hydrogen pressure. Since the process is non-invasive and does not modify the bulk material, modifying the cleaning parameters is easy. EIS measurements show that, for the artificial patinas, the impedance increases while the patina is growing on the surface and then drops, probably due to diffusion reactions and a slow dissolution of copper. It appears from these results that the dissolution of copper is heavily influenced by diffusion phenomena and the corrosion product film porosity. Both techniques show good results for cleaning, as long as the proper parameters are used. These depend on the nature of the artefact and the corrosion layers that are found on its surface.
