Joseph sold his quarter share in Cyfarthfa in Jan. 1813 for £20,000. Accompanied by Matthew Wayne , an experienced Cyfarthfa agent , he bought the Nant-y-glo works (which had immense natural advantages, but which had been at a stop for many years) as from 25 March 1811 . They soon had the works restored, and before the end of the first year were loading their pig-iron into barges on the Monmouthshire Canal . Production increased year by year. Even during 1816 , the year after the end of the Napoleonic wars , when there was a general slump in iron manufacture, and acute unrest throughout the country caused by the high cost of wheat, Nant-y-glo was the only iron-works which actually increased its export. It is not known whether Crawshay Bailey was assisting or not, but during 1820 Wayne transferred his interests in the works to Crawshay Bailey . The two brothers soon made Nant-y-glo one of the great iron-works of the kingdom. By 1823 they had five blast furnaces in operation, and in 1826-7 added two more. They had also been fortunate to add the Beaufort iron-works to their Nant-y-glo works . This was obtained by agreement with Messrs. Kendall and Co. ( 17 Jan. 1833 ), possession being given ( 25 March 1833 ) for the sum of £45,000. Joseph 's wife, Maria , daughter of Joseph Latham of Llangattock , Brecknock (who had been managing partner in the Beaufort iron-works ), d. at Nant-y-glo , 27 May 1827 .
Having amassed a large fortune, Joseph set about purchasing estates in Brecknock , Radnorshire , Herefordshire , Glamorgan , etc. Among them was that of Glanusk Park , where he lived for the rest of his life, having in 1830 retired from personal direction of the works. His brother Crawshay Bailey now had the responsibility of management.
On 19 Aug. 1830 Joseph m., as his second wife, Mary Ann , daughter of J. T. H. Hopper of Wilton Castle , co. Durham . He was high sheriff of Monmouthshire ( 1823 ). On 8 Jan. 1835 he was elected M.P. for the city of Worcester , which he represented until he was returned ( 2 Aug. 1847 ) as member for the county of Brecknock . He was made a baronet in 1852 [and d. 20 Nov. 1858 ].
