The Antique Shisslers Pharmacy Glass Dose Cup from Shamokin, Pa. in Northumberland County, Pa. is a rare and collectible piece that harkens back to the pre-1930 era of scientific and medical history. This dose cup, used in apothecary and pharmaceutical practices, showcases the craftsmanship and design of the time period, making it a valuable artifact for collectors and enthusiasts of vintage medical relics. Its unique history and charm reflect the bygone era of traditional medicine and drug preparation. I believe it’s made of magnesium glass please for the pictures.
