This 1800 silk wedding dress has stains caused by improper
storage. The garment was, at one time, stored with paper, cardboard
or wood touching the front of dress.
Ordinary paper, cardboard, woods, and even plastic products,
unless created specifically to archival standards, are made using
acids. These acids are released naturally over time and cause
staining and deterioration of the objects they touch. Dust, a
complex mixture of abrasive particles and corrosive chemicals,
is especially hazardous to textiles. It can cut fibers and hold
moisture, which causes damage at the inter-fiber level. Other
chemical pollutants, such as sulfur dioxide, ozone, and nitrogen
dioxide, are expelled into the air as automobile exhaust, created
by industry, and emitted by many manufactured products such as
paints and adhesives. All will cause irreversible stains on clothing.
