This is the fourth drawing from a series of twelve watercolours which show the manufacturing processes of Doulton's Lambeth pottery works by William Rowe about 1893. In this drawing, throwers are either working in pairs or working alone to shape soft clay with their hands and the assistance of potter's wheels. On the ground near the line marked '5' lies a piece of failure. On the wall, calibration tools are hung. To the right, a man is checking quality of a finished piece. Above the drawing, the painter indicated, in pencil, that the process represented was that of 'throwers at work'.

This drawing, along with other drawings in the series, provide a unique insight into the workings of the Lambeth factory. They not only depict processes from digging, grinding and purifying clay, to modelling, decorating, glazing and firing the finished piece, but also include portraits of Doulton's most important and influential designers and craftsmen, such as the Barlow sisters and Mark Marshall.

The set of drawings remained in the archives of the factory for many years until the dispersal of the Doulton material, when they were bought by the collectors of art pottery, Allen Harriman and Edward Judd. The designs seem not to have been executed in ceramic form as panels or a frieze as intended. However, it is recorded that a set of full-scale drawings was made and displayed at the Chicago exhibition in 1893 and were later purchased by Northwestern University Guild.
