This flint glass pitcher was produced in the United Stated at the Boston Sandwich glass factory in the late 19th century. It measures 5 1/2 inches high. It is cranberry opalescent hobnail with a clam broth attached handle. There is a rosette connecting the handle and a wide polished pontil on the bottom. The pitcher rings like a bell when tapped. The pitcher has a sensuous quality about it. The glass feels slick and smooth until you come to the hobnails that increase in size from top to bottom. Light coming through it makes the hobnails radiate like pools of oil. This is a rare and wonderful piece of American glass. The colors are sensational.
