FactoryRegistry lists 1,282 facilities whose primary industry classification is one of the 2 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced other glassware, including balls, radomes, nose cones, vials, etc. (excluding glass nursery bottles and parts for lamps and lighting), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
The U.S. Census Bureau recorded this product line in 2 US manufacturing industries in the 2022 Economic Census, as the most specific line those industries reported, where 32 establishments reported producing it.
