O papel perfurado é um material rígido muito usado como suporte de bordados na 2.ª metade do século XIX, mas muito pouco conhecido actualmente. Os casos de intervenção são raros e, por isso, apresenta-se aqui a intervenção de um exemplar bordado com missangas de vidro, de 1879, que se encontrava em mau estado de conservação. A intervenção foi complexa, sobretudo devido à fragilidade da obra e à existência de diferentes materiais ligados entre si que não permitiam os tratamentos a que estes são habitualmente sujeitos quando isolados. A operação mais complexa foi a acção simultânea de microconsolidação e micropreenchimento que envolveu a inserção de fibras de papel japonês e Tylose MH300 a 4 % entre as camadas do papel perfurado e a inserção de tiras de papel japonês por entre as linhas do bordado, entrelaçando-as com estas. Para o acon-dicionamento do bordado, foi necessário simultaneamente evitar as condições mais desfavoráveis para a conservação do vidro e do papel. Perforated cardboard is a rigid material widely used during the second half of the 19th century as an embroidery support, but very little-known today. Intervention cases are rare, and so an intervention on a poor condition 1879 glass beads embroidered specimen is presented here. The intervention was a complex task, mainly due to the fragility of the object and the existence of different materials linked to each other, that did not allow the execution of treatments to which they are usually subjected when isolated. The most intricate operation was the simultaneous action of mi-cro-consolidation and micro-infill. These involved the insertion of Japanese paper fibres and 4 % Tylose MH300 between the perforated paper layers, and the insertion of Japanese paper strips between the embroidery lines. For the embroidery housing, it was necessary simultaneously to avoid the most unfavourable conditions for both the preservation of the glass and the paper.
