This is a set of Japanese Kutani tea cups with lids and saucers. The date is that last part of the 19th century, circa 1890, and made in the Kutani region of Japan.
A covered cup is not the same thing as a pot-de-crème.
The porcelain is eggshell thin. You can see your fingers through the delicate cups.
The saucers are 4 ½”. The cups are 2 1/8” by 2 ½”. The lids are 2 ¾”.
The pattern is one of a chrysanthemum type of flower on long stems with green and gray leaves. On the cups, there is a flower outlined in red with green and a yellow center. On the opposite side the flower is outlined in black. The same flowers are shown on the saucers and lids, except there is more use of pink and green. On the saucers and lids there are flying birds, one on each piece.
The shape of the cup is round with a dainty handle meeting the body of the cup in two places at the top and bottom. The finial of the lid is round with a gold accent trim.
The gold trim around the edges of the saucers and lids is mostly worn away. One cup has a long crack down the side and another cup has a small chip at the foot base, on the edge. There are no other chips, cracks or crazing. There are some black ash kiln marks, tiny flecks of ash in the glaze on a few of the pieces, which is an indication of the age of the set.
The set is quite beautiful.
The set has a red overglaze Japanese language mark on the underside of each saucer.
