Environment museums – an area in progress
Eva Edsler

Abstract

An environment museum is a concept including manors, cottages as well as industrial plants. All these buildings have the same kind of problems to deal with. To maintain such buildings a lot of resources are needed and a relatively large and well trained staff. SVK has for several years worked with this type of problem and our experience is that many pitfalls can be avoided by careful planning. Housekeeping is a way to maintain buildings from the day they where inhabited and further on into the future.

Chinese nodding figures dated to the late 1800-th century
Ingalill Nyström

Abstract

During 1999 and 2000 the department of paintings conservation has conserved two polychrome nodding figures belonging to the Göteborg stadsmuseum. It is a official and his wife. Both figures are made of unburned clay. The clay is built up with fibres. Some more fragile parts have a metal armature and other parts are covered with Chinese paper tissue. Over the clay and paper base there is a white kaolin ground and on top of that a lacquer paint. The two nodding figures have been heavily restored, with lots of overpaint. The hand and foot of the man where broken. It was easy to remove the overpaint on the face and coat of the man. The original paint appeared to be in quite good condition – The face is again light pink and the coat is plum coloured. The broken parts where glued together with paraloid B72.

The braid from Jönköping
Eva Edsler

Abstract

In the autumn of 1999 SVK received a very interesting object from an excavation in the city of Jönköping. This object came from a graveyard which had been in service between 1284 and 1612 AD. This particular grave is believed to origin from the 16TH century. The item was a braid made of copper alloy and attached to the burial dress with pins. The braid was heavily corroded and extremely fragile so the only way to remove all grains of sand was to pick each of them with a very thin pin under the microscope. After the braid had been cleansed from grains it was treated in a solution of Incralaquer in Toluen. The braid was set to be exhibited at the county museum of Jönköping so a special box was made for it. The box contained a specially designed plate where the braid was secured by a thread of cotton at the right hue. The purpose was to ensure a safe handling when the item was to be taken from its box and placed in a showcase.

The conservation of the Bible of Karl XII, printed 1703
Alternative sizingsolution for papercasting
Martin Ericson

Abstract

In the autumn of 2000 a copy of a wellknown Swedish bible, the Bible of Karl XII printed in 1703, was restored. The wooden board in the front cover had been consumed by larvas of Common Furniture Beetle and the wood was completely penetrated by small holes. The board was soo weak it had to be exchanged for a new one. This was done without damaging the covering leather or the doublure. The textblock was severely damaged and the pages and the printed plates were mended by using a leafcasting machine. A different kind of size made from a solution of Acronal 300D and wheat starch paste was tested to size the casted fibres with very good results.

Collection bag from the church of Brunn
Ingeborg Skaar

Abstract

The collection bag made of pink silkdamask with lining in brown leather is made at Licium, Stockholm, probably in the 1940s. When the bag came to SVK, it was in a bad condition. The silk was brittle, damaged and bleached and the whole collection bag was slightly deformed. It was cleaned with a vacuum cleaner and to the leather lining moisture was added to get the right shape back. The conservation was traditional, dyed silk was placed under the damaged damask and sewn with dyed silk.

Results from analyses of the chinese nodding figure
Ingalill Nyström

Abstract

The following analyses have been made on the nodding figure belonging to Göteborg stadsmuseum: Pigment and dye, binding media, clay and fibre. The analytical methods have been ESEM, FT-IR spectroscopy, gas chromatography, pyrolyse gas chromatography, X-ray etc. The pigments used are cinnabar, red lead, prussian blue, lapis lazuli, malachite, black iron oxide, lead white, white kaolin and gold. The two dyes are not get analysed but its probably madder lakes. The binding media is still quite unsure, but it seems to contain some pine resin (rosin). The dull blue paint contain animal skin glue. The clay seems to be a quite pure china clay, that is kaolin. The clay is built up with cotton fibres. Metal pins and wooden pegs are used as an extra reinforcement. The Chinese paper tissue on top of the clay is made of linen/flax fibres. The hair and beard seem to be either human hair or horsehair, though more probably horsehair.

X-radiography – a tool for conservators
Inger Nyström

Abstract

A course in radiography, held at The University of Bradford, UK, has given deeper understanding to the subject. Some of the topics like, how intensifying screens can affect the radiographic image, how an analogue image can be digitalized and manipulated for better understanding and quality assurance are presented in the article.

X-radiography II
Reference series on objects of iron and copper alloys
Anna Gustafsson

Abstract

This article relies on a study that was carried out during my four weeks scholarship project at SVK during year. A full report on the documentation of the study is also written. The purpose of this reference collection is to see how the choice of voltage and time of exposure effect the quality of the radiographic image, regarding penetration, definition and detail. Two series were made, one with objects of iron and one with objects of copper alloys. The objects were different in thickness and surface, some objects had ornaments. Both series were made with two different x-ray films to find out what kind of effect the choice of film had on the result. Intensifying lead screens were not used. The radiographic images can be used as working tools and in relation to education. Therefore there are reasons to increase this study to cover a greater extension of materials and to include and compare with images intensified with screens.
