Blown Three Mold GV-8 (Baroque pattern) Boston & Sandwich Glass Co, 1830s. Rich cobalt blue color. An exceptional piece or Early American Glass! You can find these quite regularly in colorless, and occasionally, you will find the quart in blue… but the pint example in a rich cobalt blue is a tough one for sure! Strong impression, flared lip, open pontil base, and matching stopper that fits quite well! The slightest touch of interior haze, otherwise excellent condition. This one will brighten up any display case, china cabinet or window! If you are looking for a great piece of blown three mold for your collection, this is the one!
