It does not mention that it is a byproduct of the manufacture of gunpowder.

Nobels explosives which started off by manufacturing dynamite for mines and quarries, but ended up manufacturing TNT when WW1 came along and the Boer War before that, happened to be the main manufacturer dealing with carbon black in those days as it was a waste product they had no use of in the manufacture of explosives. It is wierd that it was not even mentioned on wiki. Nobels sold loads of it as they were only too pleased to find people that wanted the stuff! Products made from the waste material were often formed into very good and protective barn and shed paint. It was why barns using corrigated iron sheets were nearly always black.

There used to be a large plant by the Shropshire Union Canal near Ellesmere Port, in Cheshire.

It was Cabot Carbon.

Basically, the plant burned oil, and collected the soot, which was Carbon Black.

The plant gave off a large amount of heat, some of the pipe work glowed red, and there was a blue haze on top of one of the chimneys, visible after dark...

The canal adjacent to the plant was one of the last parts to freeze in winter!

This plant is no more, the site was cleared, and is now used for other purposes.

Not only is it produced by burning fossil fuels, but to maximise output it has to be air starved combustion! Even the production was a filthy process. Don't think "well it's a good job the place has been pulled down" it just means that it's now being produced somewhere in the world where they care even less about pollution.

At the time I was made redundant from the tyre factory the company were having to source from Russia, with a noticeable deterioration in consistency and quality.
