Norman Tennent has been researching this subject extensively, and he
and I will be presenting a paper here in Corning at the 2010 ICOM
Ceramics and Glass Conservation Working Group (October 3-6).

We have also used Ciba-Geigy dyes (Microlithe); Brenntag )Macrolex)
and BASF (Heliogen).

You may find it difficult to assess or quantify the yellowing as
being attributed to the epoxy or the dyes, even with controls.
