I don't get cruising world but Corning dishes have been around since the apollo space missions.
I would suggest finding or building a box for them that allows them to be stored flat. There are no dimensions on your drawing and it's 2D I can't tell if it's a box or a design to store them on edge.
Since this is pretty much a tempered glass plate, the weakest point is the edge, so I wouldn't store them on edge. Most dinner plates are 9" , but the corning might be a little larger. You would need to stack them, measure the height of the stack and the circumference and find or build a box for them. I might line it with something like neoprene? or a thin closed cell foam.
I've seen boxes like this at boat shows, and you might find them in some china stores.
