Textile Instability
In some cases, the textiles are weakened not by outside causes such as light or pests, but by chemical reactions taking place within the fabric itself, such as the oxidation of iron-based mordants over time, which can cause darkening and discolouration in the surrounding fibres.
One example which is cited frequently throughout the literature is the case of “shattered silk.” During the late nineteenth and early twentieth centuries, many silk manufacturers treated their fabrics with metallic salts (usually containing tin and iron) to give them a heavier, more luxurious feel. However, as these fabrics have aged, the metals in the fibres have accelerated their decay and caused them to become extremely brittle. The shredded or “shattered” effect this causes is the reason for the name. In this case, the environment of the textile contributes very little to the deterioration from the metallic salts, though exposure to light may accelerate it even further.
Textile preservationists should be familiar with their collections and the history and provenance of their pieces. Chemical tests can reveal the types of dyes and mordants used, as well as any other treatments applied to the fabric. Such knowledge can lead to the prevention of further decay by learning which pieces need to be handled with particular care.

Famous quotes containing the words textile and/or instability:
“The textile and needlework arts of the world, primarily because they have been the work of women have been especially written out of art history. It is a male idea that to be “high” and “fine” both women and art should be beautiful, but not useful or functional.”
—Patricia Mainardi (b. 1942)
“The difference between tragedy and comedy is the difference between experience and intuition. In the experience we strive against every condition of our animal life: against death, against the frustration of ambition, against the instability of human love. In the intuition we trust the arduous eccentricities we’re born to, and see the oddness of a creature who has never got acclimatized to being created.”
—Christopher Fry (b. 1907)
