Resumo

Este estudo pretende usar uma abordagem multi-analítica para mapear e identificar os pigmentos usados num sarcófago de madeira policromada (Época Baixa), assim como proporcionar um mais detalhado conhecimento das técnicas de pintura e do seu estado de conservação. Além disso, os autores estão especialmente interessados na identificação das espécies de madeira. Estas foram identificadas através da observação, ao microscópio óptico de transmissão, de lâminas delgadas e a camada cromática sobre a madeira foi analisada com o recurso a diferentes métodos de exame e análise. Além disso foram igualmente identificados o material de consolidação utilizado numa intervenção anterior e os sais. A fotografia técnica proporcionou informação útil sobre a distribuição espacial dos pigmentos originais e dos materiais usados em anteriores intervenções. A luminescência visível induzida foi sobremaneira útil para se perceber a distribuição do azul egípcio, mesmo quando em concentrações vestigiais ou misturado com outros pigmentos. No entanto, a caracterização detalhada dos pigmentos só foi possível através dos outros métodos usados.
