Question:
I inherited a set of Red Wing Lute Song dinnerware when my parents passed away. I want to know if these can be used in a microwave. The number on one piece is 240. Ted

Answer: Lute Song dinnerware is most likely safe to use in a microwave but to my knowledge there is no documentation on this subject.

Over the years nearly all of Red Wing’s promotional literature for their dinnerware states that it is "Oven Proof". In the late 1950s "Detergent Safe" was added to the brochures. But microwave ovens and dishwashers were not common household appliances at this time, and the brochures do not mention using Red Wing dinnerware in them. I’m not aware of any organized effort to study this issue, so trial and error is the only real way to determine whether or not your dishes can safely be used in a microwave or dishwasher.

That said, my family used a set of Red Wing dinnerware (not Lute Song but another pattern) for many years as our everyday dishes. We used them to warm food in a microwave and washed them many times in the dishwasher with no problems. I expect you would have the same results with Lute Song.
