This polysaccharide is generally known in conservation for its advantages as a product to consolidate matte paint. Because of variations in quality of the traditional funori, the authors developed an extraction method and a purification procedure to obtain the pure polymer called JunFunori®. The improved consolidant was tested in comparison with traditional aqueous consolidants such as gelatin, sturgeon glue, Klucel E (hydroxypropylcellulose) and Methocel MC (methylcellulose). The investigations showed that, in contrast to consolidation using Klucel E and Methocel MC, consolidation using JunFunori hardly changes the appearance of an unbound pigment layer consisting of a mixture of vine black and chalk on canvas. Accelerated aging tests with simultaneous ultraviolet (UV) irradiation and variations in humidity, in combination with mechanical tests and Fourier transform infrared (FTIR) analysis, demonstrated that JunFunori shows good stability under these specific conditions. In viability tests, JunFunori was as resistant to biological attack as the other consolidants tested. These results indicate that JunFunori demonstrates high potential as an alternative to traditional consolidants.

Funori is a polysaccharide extracted from the red alga Gloiopeltis furcata. This polysaccharide is generally known in conservation for its advantages as a product to consolidate matte paint. Because of variations in quality of the traditional funori, the authors developed an extraction method and a purification procedure to obtain the pure polymer called JunFunori®. The improved consolidant was tested in comparison with traditional aqueous consolidants such as gelatin, sturgeon glue, Klucel E (hydroxypropylcellulose) and Methocel MC (methylcellulose). The investigations showed that, in contrast to consolidation using Klucel E and Methocel MC, consolidation using JunFunori hardly changes the appearance of an unbound pigment layer consisting of a mixture of vine black and chalk on canvas. Accelerated aging tests with simultaneous ultraviolet (UV) irradiation and variations in humidity, in combination with mechanical tests and Fourier transform infrared (FTIR) analysis, demonstrated that JunFunori shows good stability under these specific conditions. In viability tests, JunFunori was as resistant to biological attack as the other consolidants tested. These results indicate that JunFunori demonstrates high potential as an alternative to traditional consolidants.
