This is an ancient Islamic bowl made of ceramics. This object, WAM 1913.17, was previously called Sultanabad. The term Sultanabad refers to old objects that are very high quality. Because the bowl was previously called Sulatanabad, it is possible that the bowl belonged to a group of ceramics called the Sultanabad wares. This would make the bowl very valuable and luxurious at the time. 
The colors consist of metallic lustre and deep blue which were heavily used during this time in Iranian, also known as Persian, ceramic bowls. Lustre ware can be seen on number Islamic ceramics, as it served a lovely purpose of outlining inscriptions and images. 

The WAM 1913.17 Bowl has vertical blue curves outlining the lustreware on the exterior which resembles a petal formation. Another bowl that has blue along with shining lustre, and is divided into symmetrical sections, is this bowl from the Metropolitan Museum of Art. 
The interior of the MET bowl contains vegetal designs, with delicate flower-like patterns. Similarly, the WAM 1913.17 Bowl has vertical blue curves outlining the lustreware on the exterior which resembles petal formation. Additionally, the two bowls are covered in deep blue dots within the initial designs. The blue pigmentation brings a warmth and deep contrast between the lighter colors used. The images on the curving sides of the bowl are animals and birds with an iridescent glow, separated into eight symmetrical sections. Animals and birds are highly regarded in Islamic culture and these designs were often seen in ceramics from Rayy, Iran.
