Stabilisation is the conservation process of halting or slowing the deterioration of an object so that it can survive safely, without necessarily restoring it to its original appearance. The aim is to make a piece sound and secure while preserving as much of its original material, surface and evidence of age as possible.
Typical stabilisation work includes consolidating flaking paint or gesso, re-adhering lifting veneer or inlay, treating and consolidating timber weakened by woodworm, securing loose joints, supporting fragile textiles on a backing fabric, and arresting active corrosion on iron, bronze or silver. Controlling the environment, particularly humidity, light and temperature, is an essential part of the process, since many forms of damage are driven by fluctuating conditions. Stabilisation sits at the cautious end of conservation practice and is favoured by museums and careful collectors because it is minimal and, where possible, reversible. For dealers and buyers, a piece that has been stabilised rather than heavily restored often retains more of its value and character, and a written record of the treatment is useful documentation to keep with the object for future owners.
