Samenvatting
Funori and JunFunori are highly suitable for the consolidation of matte, powdery paint layers. They minimize the risk of optical changes such as the formation of tide lines, darkening, or unintended gloss. Case studies have identified other interesting applications for the two consolidants: as cleaning agents for the removal of water stains and as media for matte retouching.
JunFunori is a new algae-based consolidant. Its traditional Japanese counterpart Funori shows considerable fluctuations in quality. For example, the pH value of 10 different samples was found to vary from 6.2 to 10.4. This inconsistency led to the development of a new purification process that was used to produce JunFunori. Unlike Funori, the first generation of JunFunori (2003–2006) was an almost standardized product. However, recent studies indicate that the quality of JunFunori produced after 2006 fluctuates considerably. Both consolidants are made from red algae. Funori is sold as bleached and dried yellowish-brown mats of algae, which can be soaked in water, warmed, and filtered to produce a yellowish-brown, cloudy adhesive solution. The algae used for JunFunori are not bleached. A gentle extraction and filtering process removes most of the colourants, salts, and proteins. Dissolved in water, the purified product produces a colourless, odourless, and pH-stable consolidant.
