Could be. I think when it comes to pigments, different is the operable
word. Although you term intensity does have a ring to it.

Sardines? You caught me with that one.

Good point that is if you can afford good handmade shoes. maybe in EU you
can get them but here they are e x p e n s i v e ! I get my tennies at

I doubt anything is coming out of Sudan but some form of terror. Sort of an
anarchic state like Somalia I think.
Ours is a food grade gum. We mix it ourselves. messy and time consuming. We
also have a commercial grade liquid that Livick recommended. Meridel
Rubenstein uses our liq from powder too.

Try burning it couldn't hurt. You're way ahead of me on this pigment thing.
Maybe a cottage industry brewing here? Need a retailer?
Cheers.
