This is an antique Adderley's, England molded ironstone lonely saucer made in the late Victorian era, 1890-1900 with a pattern called Blue Chelsea sprig with applied blue decoration on white.

The pattern originated in the 1780s and was made under several different names by several potters and was very popular especially during the Victorian era.

The saucer is 5.35 inches in diameter.

There are no chips or cracks, but there is an occasional mineral speck from the firing process.
