What is art conservation?
Our conservators treat, document, and study the museum’s collections of paintings, paper drawings, textiles, decorative arts and design, installations, and electronic media.
The museum’s department of conservation has the principal responsibility for taking care of the objects in the museum’s collections. Among other things, this entails ensuring that the conditions during exhibitions, in storage facilities, or during transport help extend the lifetime of the works of art as much as possible.
Sculptures and Installations
The National Museum’s collections of sculptures and installations encompass everything from “classical” stone and bronze sculpture to modern sculptures and installations.
Many of the National Museum’s more recent sculptures and installations use unconventional materials and methods. Some of the works also include kinetic elements.
A quick guide to conservation of sculptures and installations
-
1. Assessing the condition
Is the object undergoing a process of degradation? Has any new damage occurred? We document the condition of the piece in text and images and repair any damages that may have occurred, so that the sculpture is stabilized. Sometimes it may be necessary to analyse the object in order to identify the materials or techniques the artist has used, so that we may choose the optimal method of conservation.

2. Establish guidelines
We establish guidelines for how the objects are to be handled, displayed, stored, and packaged, so that its lifetime may be extended as much as possible.

3. Correct treatment
Many sculptures and installations contain industrially manufactured items, machines, or other gadgets that have been modified and repurposed. It is therefore essential to consult experts from other fields when the conservator’s own expertise falls short, for example when repairing neon lights, compressors, or cooling elements.

4. Documentation
In addition to combating the three main threats against the lifetime of the object, namely chemical, mechanical, and biological impacts, the conservator who works with sculptures and installations must actively document these objects.
Decorative Arts and Design
The National Museum’s collections of decorative arts and design span a period of time from antiquity until today.
The fields of decorative arts and design encompass numerous disciplines and an even greater variety in the materials used. The National Museum’s collection includes items from a wide range of genres, such as jewellery and objets d’art made from precious and base metals; wood and ivory carvings; glass objects and ceramics; furniture, mirrors, and other furnishings; and industrial design in all kinds of materials and styles.
Most of the disciplines build on traditional arts and crafts, but more recent items in the collection often blur the disciplinary boundaries in regard to material, technique, and style, so that the boundaries are not as clear-cut.
Painting Conservation
The painting conservators at the National Museum are responsible for around 6,500 paintings, ranging in time from the fifteenth century until the present day.
The collection consists mainly of Norwegian paintings on canvas, but also includes important European paintings, icons, and portrait miniatures from various eras, as well as an ever-expanding collection of modern and contemporary works.
The materials and techniques used in these works vary greatly.
The collections include works where the artist has used binding agents such as oil, acryl, egg tempera, glue, PVA dispersions, wax, natural and synthetic resins, and house paint, but also foodstuffs such as gelatine.
Painting surfaces range from primed canvases and wood panels to fibreboards, metals, and plastics.
Paper
The National Museum possesses a large collection of paper-based materials, including around 50,000 drawings and prints.
The National Museum also owns more than 300,000 architect’s drawings, as well as a large photography collection. The collection ranges from the late fifteenth century until the present day. Currently the museum employs three paper conservators to look after its sizeable and varied collection.
Paper is an intriguing material. However, people often forget how many different types of art are actually made on paper, such as pencil sketches and watercolours; pastels and gouache; prints; drawings in charcoal, chalk, and ink; and many types of photography – and this represents merely a tiny fraction of all the various techniques and materials that one comes across.
Paper’s felt-like structure enables it to be a very strong material, even as it is flexible and absorbent.
Textile Conservation
The National Museum has an extensive collection of textiles that range in time from the early Middle Ages until today.
The collection consists mainly of Norwegian and European textiles and historical clothing, tapestries, textile furnishings, and modern decorative arts.
A textile in a museum collection is a source of history. It should be treated accordingly so that it lasts as long as possible and provides us with accurate historical information.
Textile as material
An eclectic textile collection, such as the one the National Museum possesses, features a wide variation in materials and techniques. Natural fibres such as wool, silk, cotton, and linen represent the main group of materials, but synthetic fibres such as viscose rayon, acetate, polyamide, polyester, and acryl are becoming ever more common. In the future we must be prepared for these more recent, “intelligent” materials.
A wide variety of techniques have been used throughout the ages, with woven textiles such as carpets, curtains, upholstery, and clothing textiles representing the largest portion of our collection. Other techniques that feature prominently include knitting, lacework, crochet, and embroidery. Textiles are often used in combination with other materials, such as hide, leather, wood, glass, rock, metal, paper, and plastic. This encourages a good deal of interdisciplinary cooperation with our colleagues from the other material groups.
