I plonk these types face up and float them
on a bowl of cold water, let the water soak through from the back
and just wait till they separate of their own accord.
A very gentle wave in the water to remove gum
and lift with the palm.
Pat dry with a clean tea towel, place in a freezer bag sandwich
in the pages of an old book, they come out flat as a halibut.
Good luck.
