Lead wool consists of thin strands of lead metal that can be used to cold-caulk cast iron and steel pipes. [1] It was manufactured by the New York Lead Wool Company in the United States[2] and by The Lead Wool Company, Limited in Snodland, Kent, England.[3]
The Lead Wool Company (the British company) was incorporated on 9 October 1919[4] (although some references indicate that it was active before that date) and was still active in 1983.[5] The British company also developed a device to test pipe joints internally.[6]
The company's factory had been demolished by 1994, according to a report on archaeological excavations near the factory's site.[7]
Lead wool is presently manufactured in the UK by Calder Industrial Materials Limited.[8]
