“…; and in chemical field as an electrode binder for electrolyte cells. For a few years, agar has also been used in restoration, for the cleaning of different types of works of art (mural painting, wood, stone, plaster, paper, and textiles), for its ability to control and limit water release onto artistic materials, and for its respect for the substrate(Iannucelli and Sotgiu 2009;Gorel 2010;Sansonetti et al 2012;Casoli et al 2013;Nualart-Torroja et al 2013; Shaeffer and Gardiner 2013; Baglioni et al 2014; Gulotta et al 2014). Recent studies evidenced that after agar applications on porous art works no residue remains inside the porous materials (measured by FTIR spectroscopy and mass spectroscopy)(Cremonesi 2013; Tortajada Hernando and Blanco Domínguez 2013).Agar gel has also the advantage that it retains water-soluble dissolved substances like a sponge, reducing post treatment cleaning of the surface, and suggesting its ability to be used not only to clean surfaces but also to extract salts (Anzani et al2008; Cremonesi 2013; Gulotta et al 2014).…”

Biocleaning of Cultural Heritage stone surfaces and frescoes: which delivery system can be the most appropriate?

The use of the advanced biotechnology of microbiological systems for the biological cleaning of Cultural Heritage (CH) has been recently improved and optimized taking into account different factors. Biocleaning systems have been indeed applied to historic buildings, statue,s and frescoes. Such application has developed new techniques and optimised and refined the existing systems. These systems remove altered forms like sulfate and nitrate crusts and organic substances like animal glue in a more effective, less invasive way than the traditional cleaning techniques. This review focuses on several delivery systems (sepiolite, hydrobiogel-97, cotton wool, carbogel, mortar and alginate beads, agar, and arbocel) used for the biocleaning of Cultural Heritage, comparing their main properties and characteristics, making a critical evaluation on how easy they can be applied, and on their future potentiality as ready-to-use and risk-free formulates. Therefore, this review will help conservation scientists, conservator-restorers, and researchers in the field to choose the most appropriate delivery system for any specific applications

“…4) due to the low impact of the silicone solvents on these paints, and the highly controlled aqueous exposures afforded by these systems. Aqueous-based rigid gels were also included, such as the polysaccharide gels Agarose and Gellan gum [25][26][27][28]. Another series of novel aqueous-based gels-the Nanorestore ® series-which offer unique flexibility and solvent retention, and with the promise of enhanced performance were also considered.…”

Roy Lichtenstein's Whaam! (1963) is an iconic artwork in Tate's collection (T00897). Over the past 50 years, the painting has been on almost continuous display and had accrued a layer of deposited soiling, which resulted in the dampening of Lichtenstein's vibrant colours and the masking of numerous subtleties across the painting surface. This paper outlines the design and execution of an optimal soiling removal strategy for this challenging work; utilising collaborative, practice-based research. The conservation treatment employed was derived through an iterative process that reflected and supported the conservation decision-making process. The research strands included: technical and art historical investigations to determine the materials and construction of Whaam! and to define the aims of the conservation treatment; preparation of accelerated aged and artificially soiled test (mock-up) paint samples based on contemporary equivalent materials and a comparative evaluation of a range of established and novel soil-removal systems, followed by further tailoring for use on the work of art. The range of cleaning systems evaluated included free-solvents, gels and emulsifiers; which were documented using star diagrams, digital microscopy and infrared spectroscopy. After a rigorous process of assessment and refinement, the strategy taken forward to Whaam! included the use of a polyvinyl alcohol-based polymeric hydrogel (Nanorestore Gel ® Peggy 6), uploaded with tailored aqueous solutions. This process facilitated a low risk, controlled and even-removal of the soiling layer, enabling the successful treatment of this sensitive painting for the first time in the painting's history.

“…Cellulose ethers, carboxymethyl cellulose, and polyacrylic acid salified with strong bases were extensively used as gelling agents thanks to their capability to retain solvents [1,10,[14][15][16][17][18][19][20][21][22][23].…”

Organo-and hydrogels have been proposed in the restoration field to treat different types of surfaces. The possibility to retain solvents and to have a controlled and superficial action allowed to use these materials for the removal of very thin layers applied on ancient historical objects, when the under paint layers are particularly delicate and water sensitive. In the last years, an increased attention has been devoted to the proposal of more healthy products to guarantee the safeguard of the operators. Few attention has been devoted to the development of green methods which foresee the use of renewable and biodegradable materials. The aim of this paper is to test a green organo-gel for the cleaning of water sensitive surfaces like varnished egg tempera paintings. The gel has been tested experimented on mock ups varnished with natural and synthetic materials and has been validated on a small portion of a Cimabue painting for the removal of two varnishes applied on two different test areas of the painting.
