Intervenção de conservação dum bordado com missangas em papel perfurado: problemas e soluções

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 micro-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.
