does anyone know if:
• vintage cast iron like griswold or wagner ware, or
• enameled cast iron like le creuset, staub or descoware
can go straight from refrigerator or freezer:
• onto a gas range top, or
• into an oven, or
• under a broiler?
thanks for any help as i'm starting to build a small vintage cookware collection!
