This is a pair of matching Limoges hard paste porcelain vases. The Limoges maker and decorator is Jean Boyer. The date range falls into the Art Deco Period of the 20th century, circa 1919 to 1935.
The more decorative works produced by Jean Boyer are difficult to find today in the United States. Mary Frank Gaston makes this assertion in her book "The Collector's Encyclopedia of Limoges: Third Edition," page 340.
The vases are 7 ¼" high and 3 ¾" wide at the upper belly.
The white spots in the photos are light glares.
The outside of each vase has many colors running up and down the length, not quite a glaze, but not a typical ground either. The colors would have been applied by an artist working for the company and then heated to get the colors to melt or run together. The colors are in a layer over the porcelain. The result is quite beautiful, and a refreshing change from having yet another vase covered in pink roses. The colors used are blue, green, red, orange, yellow, purple, brown and cream.''
The interiors are glazed white and the rims are covered in gold.
There are no nicks, chips, cracks or crazing. The bottom edges show wear from sitting, wear against the color, or mild abrasions against the layer of color, and I show you what I am referring to in the last photo.
The maker's green underglaze mark is on one vase only. It is J B inside a banner with Limoges above and France below. The other vase has Limoges hand painted in black enamel.
