This promo film for the Mississippi Glass Company dates to the late 1960s or early 1970s, and was made by Dean Moore, Sr. and his company Condor Films. Mississippi Glass Co. was founded in 1873 in St. Louis, Missouri, initially specializing in green glass bottles and jars for export, until the production started concentrating on flat glass plates, specializing in industrial-level wired glass. This film promotes the varieties of glass plates and wired glass the company produces, showing how different glass types can change how sunlight affects classrooms, homes, and offices. Unfortunately, the film apparently didn’t help Mississippi’s business, and the company folded sometime in the 1970s.
