I haven't noticed, Terry, that you believe everything *I* tell you so
trustingly. Meanwhile we know nothing about how this fella claimed to be
a chemist (tho he obviously wasn't a gum printer) framed his "tests, or
even if he had his glasses on. The thing we do know is that he was wrong.
But who said anything about "better"? I simply said that since sodium
dichromate is more soluble in water, a saturated solution is *faster,* all
other things being equal.
I also said,

I never said "problem," Terry, I simply mentioned staining. But since almost
immediately you add (see below) that you never used sodium dichromate I
wonder why you are pressing the issue....

Wanna bet?
