Did you wet the baltic birch? What glue did you use?

My daughter has asked me to build a bookcase for her baby's nursery. She

something on-line that she likes. It has a curved top. I think I will
build
the bookcase out of birch as it will be painted and I am thinking of
laminating 3 1/4" pieces of birch plywood to do the curved top.

Here is my question. I know you have to build the lamination on a form
with
a tighter radius than you want to end up with as the wood with spring back
a
bit when you remove the clamps after gluing up the lamination. Is there
some
guidance people can give me on how to figure out that tighter radius??

I recently did a test with 3 layers of 1/8" baltic birch ply and it
didn't spring back at all. I arranged the grain of the outer plys so
they were parallel to the bend. And the 3/8" built up is hard as a
rock.
