The Library of Congress maintains a large collection of wax cylinders, many of which contain ethnographic field recordings from as early as 1890. Wax cylinders can present with several condition issues including cracking during storage.

This work has included the recreation of period formulations as well as the detailed chemical and physical characterization of the formulations.
