There are some names of manufacturers on the 1802 map of the Potteries which have not received so far, and yet deserve, special mention. The brothers John and George Rogers, for instance, built their factory at Dale Hall near Burslem about 1780. John Rogers built too, about 1800, the house called “Watlands” in Wolstanton, the home of many potters, and lived there till his death in 1816. His son Spencer Rogers succeeded to the firm, which continued to flourish for over half a century as “John Rogers and Sons.”[161] Mr Samuel Ford now owns these works. Joseph Machin of Burslem was the progenitor of the Machins of the Hole House Works, afterwards, in 1843, “Machin and Potts” of the Waterloo Works. This firm were the first successful manufacturers of porcelain in Burslem and they invented too the present method of printing the transfer papers from revolving steel cylinders, thereby greatly accelerating the work of producing these transfers and printing the ware. The Goodwins of Cobridge had no fewer than four factories in the neighbourhood as late as 1843;[162] and the firm of John Glass & Sons appears to have existed in Hanley ever since the beginning of the 18th century and the days of slip dishes and “tygs.” William Baddeley, with his works at Eastwood on the banks of the Cauldon canal, was chiefly noted for his large flint-grinding mills. Miles Mason, of Lane Delf, and his son Charles J. Mason had their factory where the Stoke and Hanley tram-lines now branch. In 1813 the elder Mason introduced the patent “ironstone” china, which became very popular and was the precursor of the “granite” trade of later days.[163] The senior partner in the firm of Bourne and Baker of Fenton made a fortune, built the church at Fenton, and bought the Hilderstone Hall estate, where his descendants now live.
