Hi Ryujii,
I just want a little bit of this stuff to satisfy a point of
intellectual curiosity; since I don't size as a rule, I have little
need for hardening agents for gelatin. I was going to order some from
Pelco (thanks Gordon) but now I'm confused. Do you mean to say that it
has to be pH adjusted in order to be useful, and that what I get from
Pelco might not be? Also, the lowest strength Pelco has is 8%, but I
assume it's only a matter of adding more water, right?
