Description
A former trademark for fine, curly wood shavings. Excelsior is used as a packing material for breakable articles. It is light and provides an effective cushioning material. Excelsior is usually made from Poplar, Aspen, Basswood, or Cottonwood and may contain a combination of several woods obtained as a byproduct from woodworking. It has been used for cushioning heavy stone sculpture and architectural elements (Shelley, 1987). However, two cautions are provided: 1) excelsior is hygroscopic and may turn into wet mush if exposed to widely varying temperatures and humidities, and 2) excelsior should not be used for shipping metal objects as any wood product may emit small amounts of organic acids, such as Acetic acid.
