of Brynamman

1836 The hot blast experiment at Ynyscedwyn enabled smelting with anthracite for the first time. These developments later led to the massive expansion of the iron industry in the USA, where anthracite was the principal coal available.

1847 The Amman Iron Company was formed when Mr Llewellyns bought existing works at Gwter Fawr from Mr Jones, of Brynbrain, and built 2 blast furnaces there. These were part of the expansion of the iron industry in the western coalfield built on the development of the hot blast.

Llewellyns built company houses in Hall Street and elsewhere

1851 The works expanded with a forge added in 1851

By 1857 there was a central projecting block for charging the furnaces; possibly the two flanking sections are also shown on this map.

1861 The forge was replaced.

1864 The name of Gwter Fawr was changed to Brynamman by the Swansea Vale Railway.

1868 A third furnace, called the Big Furnace, was added.

1862 Tin works were added across the river in Carmarthenshire - see Amman Tinplate Works.

1918 The site was marked as Amman Brick Works on 1918 OS mapping.
