The Titanian glaze – one of several new glazes perfected by the Doulton factory under the aegis of Charles Noke in the early 1900s – uses a titanium oxide which results in its blue tone.

A number of leading factory artists painted pieces for the range including Harry Allen, Harry Tittensor and F Henri - whose signature appears to this 6in (15cm) vase c.1920 decorated with a swan and cygnet, above.

With a printed back stamp titled Titanian, it is pitched at £200-300 by Special Auction Services, Newbury, on October 1.
