Masonite is preferred by conservators. You can read about it in Ralph
Mayers "Artist Handbook" It must be sized with acrylic or better yet
rabbit skin glue to prevent migration. The weakness of medieval panels
was the panel - usually oak. As it moves with temperature changes the
gesso cracks. Masonite is very stable and like the 1 billion Barbie
Dolls sold will last many many of our lifetimes. Pure fired ceramic is
even better but of course they can break.
Art lasting is not one of my concerns. But our need to want them to last
is.
