Queen Caroline medium character jug produced in Staffordshire England circa 1830. Caroline of Brunswick-Wolfenbüttel (1768–1821) was Queen of the United Kingdom and Hanover as the wife of King George IV from 1820 until her death in 1821. She was Princess of Wales from 1795 to 1820. Rejected by her King, she was loved by the people. The Pearlware finish refers to the final clear glazing that contained cobalt and gave a slight blue coloring to glaze that tended to pool between fingers and in the creases in the face.
