Hi Katherine -- I had much the same experience at first. There just didn't
seem to be many around, for a long time anyway...

Actually, not everyone does like BFK, although around here, with our
water, and the gums, & gelatin we use, it's usually excellent. But
definitely not with *every* gelatin or paint or gum. 
What gum arabic do you use?
I agree about the texture, by the way, which is why I rarely use it, but
if you like the texture and your ingredients are compatible, it seems to
be the classic all-purpose for a lot of printers (and the one I advise for
students, some of whom never leave it).

Which make of "lamp black"? If that was me who said that, I take it all
back. Further experience showed that it depends as much (maybe more) on
the brand as the "color."

So tell us your magic numbers !

Or she, either. I absolutely agree... Who could not?

But as you describe, in gum there's as much "finding" as principle. Who
could say your findings are "wrong"? Though I can't resist adding re your
success with that Anderson gum-pigment ratio test from Keepers of Light
....  even a stopped clock is right twice a day!  I'd be willing to bet
you just lucked out...  ;- )
