FactoryRegistry lists 1,349 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 chemical, technical, and industrial pottery ware and all other pottery products, including pyrometric cones, veritas rings, etc., 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 53 establishments reported producing it.

These are counts of establishments by industry: the Economic Census publishes them as industry totals and never as a list of plants.
