Antique Blue End of Day Glass Witch Ball

A great example of an antique glass witches ball with blue splotches. The ball is white lined and has a typical snapped off opening where it left the pontil rod. Height 3.5 inches, width 4 inches. This ball has a brass cap which came with it but was very loose so I have taken it out for the next owner to use or fix. English. C1820/40
