mid-19th century antique american squat body teal glass iron-pontiled soda bottle designed and fabricated by the dyottville glassworks, philadelphia, pa. the bottle contains a rounded taper collar applied to a long and narrow bottle neck with allover stretch marks and seeds. the front of the bottle contains the manufacturer's name and city, with the latter being abbreviated and having a raised "a" end-letter. several large bubbles and/or seeds are found throughout. the pontiled base contains iron oxide deposits pulled from the iron pontil rod, and a central pontil scar. the bottle is free from cracks or breaks. dyottvillle glassworks was founded by englishman, thomas w. dyott, a young, self-proclaimed doctor who began selling "medicinal" elixirs early in the 19th century in the form of vegetable nervous cordial, infallible toothache drops and stomach bitters from a philadelphia-based drug store located at 2nd and race street. his great success in the patented medicine business allowed him to purchase kensington glass works during the 1820's. there, he could produce and bottle his concoctions along with that of competitors. by the 1830's his rapidly expanding glassworks, located in the town of dyottville, pa., would employ hundreds of highly skilled glassmakers that produced over ten thousand pounds of glass a day. by 1837 the economic depression, coupled with charges of defrauding the community would spell the end to dyott's empire. at the age of 70 years, dyott was sentenced to the eastern state penitentiary. shortly thereafter, his glassworks factory would close and the small town of dyottville was essentially wiped off the map. the glassworks would later be purchased by prominent philadelphia bottler eugene rossel in 1840.
