The wooden sculpture entitlend „King Casimir the Great” , ca. 1380, which comes from the Collegiate in Wiślica, is at present the property of the Museum of the Jagiellonian University in Cracow. This is a complete sculpture, executed in limewood, with polychromy, and covered with silver and gold paint. The prime conservation problem is the consolidation of the wood damaged by insects and the adhesion of impaired polychromy on almost the entire surface of the object. The impregnation of the wood was conducted with a 20 per cent solution of Paraloid B-72 in xylene, in a vaccum chamber under pressure. The loose polychromy was glued on with ethylene polyglicol PGE 2000, polyalcohol of vinyl water, used in the following proportions: PGE 2000 - 40 per cent, PAW - 4,8 per cent, water - 55,2 per cent. The sculpture was cleaned, the paint was retouch and the badly executed linning of the coat was removed. All the missing ground of the paint layer was implemented, and the lining of the coat was reconstructed. (translated by A. Rodzińska-Chojnowska)
