I promised myself I wouldn’t start collecting English Pyrex.  I told myself, “You don’t have the room,” “You can’t afford to ship heavy glass across the Atlantic,” “It is disloyal to the American Pyrex I already own.”  Well, none of those arguments worked and I am the proud owner of a Red Hawthorn JAJ Pyrex mixing bowl.  It is approximately the same size as a US 403.  I haven’t been able to find much about this piece online, but I do know that the red version is a more difficult to find color.
