このお皿は電子レンジで使えますか？ — Can this plate be used in the microwave? (Vintage · Shopping, Formal — to staff, JLPT N4)

Hold up the plate or point to it, then make a circular motion with your finger as if turning a dial.

Some older or handmade ceramics may not be microwave-safe or dishwasher-safe. Always ask, especially for items bought from antique or vintage shops.
