Migration – Definition, Examples, History & More – Art Conservation and Restoration Glossary

What is Migration in Art Conservation?

Migration is a term used in art conservation to describe the movement of materials within an artwork over time. This movement can occur due to a variety of factors, such as environmental conditions, aging of materials, or improper restoration techniques.

Types of Migration in Art Conservation

There are several types of migration that can occur in artworks. One common type is pigment migration, where the pigments used in a painting or sculpture move within the artwork, causing changes in color or texture. Another type is adhesive migration, where the adhesives used to bond materials together break down and migrate through the artwork, causing damage.

Causes of Migration in Artworks

Migration in artworks can be caused by a variety of factors. Environmental conditions, such as temperature and humidity fluctuations, can cause materials to expand and contract, leading to movement within the artwork. Aging of materials can also contribute to migration, as materials break down and lose their original properties. Improper restoration techniques, such as using incompatible materials or methods, can also lead to migration in artworks.

Detection and Analysis of Migration

Detecting and analyzing migration in artworks is a crucial part of art conservation. Conservators use a variety of techniques, such as microscopy, X-ray analysis, and chemical testing, to identify and understand the causes of migration in an artwork. By understanding the migration process, conservators can develop effective treatment plans to prevent further damage.

Prevention and Treatment of Migration in Art Restoration

Preventing and treating migration in art restoration involves a combination of careful planning, proper materials selection, and skilled techniques. Conservators must consider the original materials used in the artwork, as well as the environmental conditions in which it will be displayed. By using stable materials and techniques, conservators can help prevent migration and ensure the long-term stability of the artwork.

Case Studies of Migration in Art Conservation

There have been many notable case studies of migration in art conservation. One famous example is the restoration of Leonardo da Vinci’s “The Last Supper” in Milan, Italy. Conservators discovered that the original paint layers had migrated over time, causing changes in color and texture. By carefully analyzing the migration process, conservators were able to develop a treatment plan that stabilized the artwork and preserved its original appearance.

In conclusion, migration in art conservation is a complex and multifaceted process that requires careful analysis and treatment. By understanding the causes of migration, detecting and analyzing its effects, and developing effective prevention and treatment strategies, conservators can ensure the long-term stability and preservation of artworks for future generations.
