This bottle is a type of container generally listed in earlier glass factory catalogs as a “Chow-chow” or “English Pickle” bottle. Chow-chow is a type of pickled relish, very popular in the Victorian era and still popular today, especially in the southern states of the US. The term Chow-chow covers a wide range of recipes. These were popular English imports in the 1890s. They came in a variety of shapes and sizes in a distinct heavy aqua. We called them Chow Chows due to some that were found with a label.
There were numerous pickle companies, but the bottles were made in England by the John Kilner & Son glass house. This one stands 8” tall and almost 3” in diameter. The bottom has the Kilner mark with a large “W” indicating the Wakefield plant ("K W 2275"). It rises to a strong rounded shoulder and a squatty neck with a distinct applied heavy ring lip. It is in dug condition but cleaned up very well so you can see the flaws and bubbles. It has some haze and a small, popped bubble near the base but no other damage.
