Hi Chris,
It sounds like you might be on to something with the heat idea, I have not
tried the Becquerel method but I have had a similar effect over mercury.

I believe my dag had a combination of over exposure and over development (if
I recall my mercury was a little warm when I developed ) maybe you had the
Becquerel equivalent to over development. I also notice this brown effect
when a dag is over heated during the gilding process.

Well good luck, with a little more work I'm sure we'll overcome these
problems.
