Formalin and formaldehyde resins in conservation

From: Barry Knight <barry>
Date: Monday, January 25, 1999
In Instance 12:60 Niccolo Caldararo asks for information about the
use of formalin and formaldehyde resins in Germany before 1900.

The only mention of formalin in Rathgen's pioneering conservation
handbook, "The Preservation of Antiquities" (first published in
German in 1898) is in the context of the control of algae and
bacteria in the vats used for soaking salt-contaminated Egyptian
limestone objects.  He does not mention urea-formaldehyde or
phenol-formaldehyde resins at all, but he does mention the use of
nitrocellulose ("Zapon") as a consolidant and lacquer.

Hope this (negative) information helps.
