A classic bottle shape in the packaging industry, the Boston Round Bottle (also known as a Winchester Bottle), can hold almost any liquid or solid. Traditionally used for pharmaceutical, chemical and laboratory applications, popular uses break the mold and extend across most markets today. Boston Round Bottles have a narrow neck size when compared to other container types, making them the ideal bottle shape for a variety of closure styles. Cobalt blue glass is appreciated for its bright and appealing color. The blue shade of this glass is obtained by using cobalt oxide.
