This is a French Limoges Haviland & Co hard paste porcelain tray or platter with a bisque unglazed bottom. The date is the 19th century, circa 1879 to 1880.
The tray is 16 1/2" long and 12 ½" wide.
An unglazed bottom typically means the function of the tray was for on top of the dresser or to hold a tea set, chocolate set or coffee set. However, more modern owners adapted the tray to use as a serving platter.
The shape of the tray shows rounded ends and rounded sides, almost like a four-leaf clover shape.
There are separate sprays of flowers, a transfer pattern from the factory, and these different sprays are considered to be part of a botanical series. The flowers are of different types and colors, with long stems, grassy foliage and leaves.
The edge of the tray is gray.
There are no chips, cracks or crazing. There is a small abrasion to the edge in one spot that removed the gray color; it isn't a chip or nick, but merely a small area with an absence of color that creates a feel of roughness. There are some glaze marks due to the firing process.
The green (usually an underglaze) mark is H&Co underscored with two lines. The blue factory decorating mark (usually overglaze) is a blue circle containing the words Haviland & Co Limoges.
