The Pranas Gudynas Restoration Centre (PGRC) is a branch of the Lithuanian Art Museum. The PGRC is primarily responsible for the long-term preservation of the Lithuanian Art Museum's collections and also assists in the preservation, conservation and technological study of collections from other Lithuanian museums, churches or institutions. The Centre is the main training base for restorers of portable cultural heritage in Lithuania. We started to use CDD around 2003, when our chemists offered this material for applying in specific conservation situations. CDD is currently used here in paper and textile conservation for fixing water-sensitive materials and as protection against aqueous solutions. This paper describes its use on four objects: two watercolour works on paper, a wooden chest upholstered with silk and metal thread embroidery, and an oil painting on silk.
