The collection consists of 38 glass exhibition flasks, each containing a particular mineral or mineral product (e.g., bituminous coal, brick clay and shale, fire clay and shale, greensand, marl). These were part of a display of Maryland's mineral resources and products, shown at a number of expositions in the U.S. during the first decade of the 20th century. The exhibition flasks are either on display (in the lobby and/or the library) or in storage at the Maryland Geological Survey. See citation below for link to MGS volume containing details and photographs of these displays.
