The white spots in the photos are light glares.
This looks like a huge teacup for a 10-foot giant. It is a French Limoges commode or chamber pot. The maker and decorator is Martial Redon. The date is the 19th century, circa 1882 to 1896.
The commode is 6" high and 9" wide at the mouth, not including the handle.
The glaze is shaded cobalt, a lighter blue at the bottom shading to a dark blue at the top. Cobalt was an expensive glaze to produce for Limoges makers because it entailed multiple firings at a high heat, resulting in more production losses. The customers for Limoges cobalt pieces were the very wealthy members of society.
The front of the commode has large flowers, leaves and stems, painted by hand in gold enamel at the factory. The handle is covered in gold and the edges are trimmed in gold.
Some porcelain commodes or chamber pots from the 19th century were made with lids. This specific commode does not appear to have produced with a lid. The shape of the mouth is incorrect for holding a lid, and there is no rubbing wear on the glaze from a lid.
Redon is a Limoges company that specialized in high end dinnerware, decorative objects and art objects.
There are no chips, cracks or crazing. There is minimal wear to the gold. There is one tiny rough spot on the bottom edge that I show in the last photo.
The green underglaze maker's mark is MR followed by Limoges France. The blue overglaze factory decorating mark is M. Redon Limoges inside a circle with Special in a rectangle below. There is also hand enameled in red the factory number of B05339.
