The cup the earpick container and the plate have mottled blue insides.
the plate was cut but the glaze filled in the gap.
the cut shows better when reversed... some of the mottled blue leaked through the gap (he he he)
the inside of the lid has a tiny bit of glaze but the rest of it is left to burn to black.
perfect spiral foot for the plate, and traditional ring foot for the cup.
3 more pieces belong to the set: Milk container, sugar container, the ring is supposed to be a strainer or better yet it's a weight for the paper filter.....
no teapot? nope, tea is made and served and sipped and enjoyed only with the cups.
