Abstract
A sample of mineral fibers is dispersed in a liquid and viscosity of the dispersion is measured. The viscosity value provides a rapid measure of the length of the fibers. The measurement is sufficiently rapid that adjustments can be made to operating conditions during a production run to ensure the production of fibers of uniform length characteristics.
