Well the physics says, a 12 inch lid has 144 square inch of surface area. Boiling water can easily give you more than a lb/sq in of pressure ( a pressure cooker cooks at 15 ibs /sq. in.) So if the boiling water gives you 1 lb/sq in of vapor pressure, your 12 inch lid will need to be at least 144 lbs heavy to keep the steam inside.
