Evaluation of chia and flax mucilages as consolidants of paint films and as hydrogels used in the cleaning of canvases reverses: first results

Abstract In the field of conservation cultural heritage, animal glues, synthetic resins, and some polysaccharides are used to consolidate pictorial layers. Meanwhile, in order clean obverse reverse paintings, organic solvents aqueous systems sometimes employed form gels. this work, vegetable mucilages have been tested for both applications. This research has carried out several phases. Firstly, were extracted from flax chia seeds. The efficacy obtained products was on two kinds mock-ups. As consolidantes, applied a board with film powdery tempera painting. case their use as cleaning gels, linen cloths prepared: one glue other gacha , an adhesive Mediterranean Basin. last step, safety treatments determined through microscopic observations FTIR-ATR measurements. Colour gloss characterisation also performed consolidated According first results shown mucilage can disintegrated layers rabbit-skin producing minimum colour changes, whereas less tempera. Regarding hydrogels, promising . With these results, future work will focus study long-term behaviour accelerated artificial ageing laying foundations treatments, such
