wood pieces are warped. Any advice as to how to prevent this? My final
pieces I want to be on Southern Yellow Pine which I've not tried yet.

You don't say anything about how thick the white pine is. I assume
it is very thin since it warped with a little water applied to it.
If you dunk the board in water and keep it there, it will absorb it
and perhaps warp. Applying the small amount for alum and then
marbling shouldn't apply that much water to the wood. I have seen
turned bowls marbled in buckets and they didn't warp at all.
Yellow pine has a lot of natural resin. If it is air dried, it has done
all the warping it is going to do. It probably wouldn't be a good
choice to take the paints unless you top coat with something. You
may want to spray fixative over the dried paint to make sure it
doesn't rub off.
Here is an article on marbling turned objects.
Good luck, Roger
