I recently took a trip out to West Virginia to visit a few different factories that were kind enough to let me in. My first visit was to Marble King in Paden City, West Virginia, along the Ohio River. Paden City was once a center of glass making with several factories in the town. Today only Marble King and a stained glass maker remain. Marble King was founded in 1949 and remains a family owned company.
Most of the marbles that Marble King produces start off as scrap glass from other manufacturers that range from glassware makers to their stained glass maker neighbor. It was pretty interesting to learn that the majority of the marbles they make are used in spray paint cans. When you shake one up, thats a glass marble in there.
