>From my study of icons in Russia, it was reiterated that many of the
makers of old varnishes for icons had "secret" formulas designed to
protect the surface of the icon for 80 years or more. Some used
amber, some used gums, so it is not unusual to find many components
of a varnish upon analysis. I would assume your analyses show that
the ingredients vary from varnish maker to varnish maker. Ivan
Bentchev is a very reliable and knowledgeable source for icon
information. I do hope you publish your findings and let me (and the
conservation community) know your results.
