capital and various other leases and
mineral rights.
The furnace was established on the hillside above Merthyr. It was not an ideal location. But all the elements for production were at hand. However, the enterprise struggled because its management was too thinly spread among the partners. In 1765, Nathaniel Webb, Thomas Price and William Lewis had become or were appointed executive partners. However, either because they 'could no longer give the expanding business their full attention, or because they felt that the enterprise needed the direction of an expert hand, on 30 April 1767 they offered John Guest the post of works manager.'
In 1781, Guest purchased 7 of the 16 shares in the works and a second furnace was built. In 1786, he was succeeded by his son, Thomas Guest, who formed the ''Dowlais Iron Company'' with his son-in-law William Taitt. Guest introduced many innovations and the works prospered.

Thomas Guest died in 1807 and his son
John Josiah Guest became sole manager, by 1815 owning nine of the sixteen shares. His brother Thomas Revel Guest owned one and Whyndham Lewis, the remaining six. Guest established the works in the vanguard of the

Sometime during 1835, Guest made the acquaintance of engineer
G. T. Clark. Both had been involved in the
Taff Vale Railway. In 1850, Clark married Ann Price Lewis (died 1885), a descendant of Thomas Lewis. Ann's brother had sold her family's last remaining interests in the firm that year, to Guest.
