Varnish

From: Jevon Thistlewood <*jevonthistlewood*> Date: Saturday, March 9, 2002 · jevonthistlewood

Does anyone know how old a dammar (or mastic) varnish layer needs to
be before it will fluoresce in ultraviolet light? Also, if a
fluorescing agent (such as Tinuvin) has been added, what is the best
way to detect it?
