1870 Danks' experiments were so successful that the company replaced all of its old hand puddling furnaces with rotary furnaces and this move was copied by many other companies in the USA

1871 Arrived in England to introduce his patent to British ironmasters, and particularly those of Staffordshire.
The Iron and Steel Institute then sent a deputation to America to investigate the process. The Commission visited the Cincinnati Ironworks, where the machine was at work, and conducted a series of experiments.

1875 The Danks furnace was also tried in North Staffordshire at the works of Messrs. Robert Heath and Sons, and at Erimus Iron Co at Middlesbrough. But, although initially made to work, it was not a success; Mr. Danks, who had personally superintended the erection of the trial furnaces, returned to America.
