Early 1900s vintage Tea Leaf pattern English ironstone pitcher, 6" tall. It's marked with the Royal Arms lion and unicorn marking, made by Burgess - Berslem (Staffordshire).
This is in shabby condition, with cracks at the bottom, and noticeable browning and staining. I don't think this would be usable for liquids without causing further damage, after about 100 years, it's now pretty much just a decorative piece.
