Register Now.

Students study crystallographic and optical properties of asbestos minerals, the various substances likely to occur (and often confused) with asbestos and the procedures for sample preparation and fiber identification. Both serpentine and amphibole asbestos types are included.

There is no prerequisite for this course.
