This is a rare sugar shaker or muffineer, in the forget-me-not pattern made by Challinor, Taylor & Co., circa 1887-1891. The color is a mauve/lavender which is pale at the top and deeper at the bottom. In fine shape, no chips or cracks. Just natural aging.
The lid is original and shows wear, it was well used!!! The top of the glass is rough as it is supposed to be, typical of this class of milk glass.
Nice on a Victorian table!!
