By October 1846 John Hall and Son had acquired the English patent for the manufacture of guncotton and commenced to build a factory for its production at the Marsh Gunpowder Works. Reputed to have been the first guncotton factory in the world. Production was brought to a halt by a disastrous explosion on 14 July 1847, in which some 20 people lost their lives. The remaining stocks of guncotton were buried on the site, production was not restrarted. (1) The precise location of this factory is unknown, no surface remains were identified during the field visit (1). Additional references to site include (2,3). Site photograph (4).

In 2019 an historic building recording of the former Marsh Gunpowder Works buildings now situated within the former Oare Mineral Works, Faversham, Kent was completed in advance of works to the designated and non- designated heritage assets. (5)
