Before I do something stupid, I figure it is better to consult with everyone. I bought a plastic measuring cup that has a beautiful pouring spout that I figure will do a great job pouring into small areas. I checked with three authorities (women) if this cup can be used in a microwave and got a posetive answer from all three. However they know nothing about plastisol. Will the plastisol effect the plastic cup? Should I not use the plastic measuring cup? Where did I purchase this cup you ask, Walmart ofcourse. Thanks, Pop
