Coalbrookdale
By 1714, Baylies had joined his brother-in-law, Abraham Darby, at his Coalbrookdale ironworks, becoming a partner with him and John Chamberlain. Together they built a second blast furnace at Coalbrookdale and secured the rights to build a furnace at Dolgûn near Dolgellau and taking over Vale Royal Furnace in 1718. However, Darby died in July 1717, before any progress was made with either project, and the partnership was dissolved.
