This Chinese teapot and round basket date mid-19th C. The set is unusual because the fitted "cozy" basket was designed to allow the spout to extrude, so the tea can be poured without removing the teapot from the basket. All of the other sets I've seen over the years have had an oval basket, and required the teapot to be removed for pouring.
The teapot's pattern does not fit the precise modern definitions of "Rose Medallion" , "Rose Canton", etc., because there are no medallions, and I have read that Rose Canton should not include birds. The design on this piece has a bird and a butterfly surrounded by flowers.
Someone once told me that this type of cozy & teapot was made for the Indo-China market...
The teapot is 5" high. The basketry cozy is 6-1/4 " and 6-1/4" in diameter.
The condition of the teapot is excellent. There are no chips, no cracks, no repairs. There is wear to the gilding on the edge of the lid. There are no maker's marks.
The condition of the basket itself is excellent. However, the interior lining shows wear. Also, there were originally 2 metal handles on the top. Only 1 remains.
