Their distinctive Mel-Rose glaze combinations are said to have been the intellectual property of Francis Manallack, an expert in all facets of pottery-manufacture but especially glaze-making. Francis had spent many years working for Cornwell’s pottery (also in Brunswick), he worked for a time as a chemist for the Melbourne Glassworks, and taught classes at Brunswick Technical School. He contributed his glazing expertise not only to the Mel-rose line, but also to Mc Hugh Brothers art ware, leaving his mark several times over in the history of Australian pottery.
Merric Boyd, sometimes described as the father of art pottery in Australia, had his pots fired in Hoffman kilns in the early 1930s after he burned out his own. Merric is also thought to have modelled some decorations for use in the Mel-rose line. Allan Lowe, William Ricketts, John Barnard Knight and Klytie Pate are other studio pottery artists who were associated with Hoffman’s at one time or another.
