I found this image of this vase in one of the digital tables at the Cooper Hewitt Museum. It was given to Christopher Dresser and manufactured by Minton’s Art Pottery Studio. There are different shades of blue from this point of view, and that is what caught my attention. It is dated 1870s and was acquired in 1998. It is a medium glazed porcelain, and part of the  Product Design and Decorative Arts department.
