New Street is in Burslem town centre - it is a short street running from Wedgwood Place (at the edge of Market Place) to Greenhead Street (which used to be High Street).

From "A descriptive account of The Potteries (illustrated)
1893 advertising and trade journal. Page 54" we know that Messrs. John Maddock and Sons, New Street Pottery, Burslem operated a pottery in New Street.
