Lokal konservering av bok med mögelskador Förstärkning med Klucel® G
The aim of this paper is to make a plan for local treatment with Klucel® G of a book with moulddamage. The biggest problem concerned handling the book without loosing fragments and tohandle pages that were stuck together. In some places as many as six pages where stuck togetherand it was not possible to separate them without loosing material or breaking them. The otherproblem concerned the use of waterbased adhesives that might cause tidelines and paperdistortions as seen in another volume. The use of Klucel® G dissolved in ethylalcohol functionedvery well as strengtheners and also as an adhesive for lamination. Though it was not strongenough to hold the infillings and a solution of Tylose® MH 300 P2, dissolved in minimum waterand diluted in ethylalcohol, was used there instead. This paper also investigates cellulose ethersthrough a review of literature concerning their stability for longterm use. In general, the celluloseethers used in conservation are stable for longterm use, even though there are differences amongthem and it is necessary to evaluate wich one to use for a specific object. Different moleculestructures, results in different properties and therefore it is vital that tests that makes comparisonsare done on the same cellulose ethers. Different viscosity, concentration and trademarks made itdifficult to make a fair comparison in the articles read. The conclusion is that more tests needs tobe done.
