Whilst studying ceramics at the Liverpool School of Art (1936-1939), Margaret Leach (no family relation to Bernard) spent two months of her summer holidays working at the St Ives Leach Pottery.

She returned as a member of the Pottery team in 1941, and spent three years learning all aspects of pottery production, and took over the Barn Pottery at Brockweir, Gloucestershire in 1946.  She worked mainly in slipware, regarding it as her natural medium, and employed a range of colours from black, dark brown through to reds and bright yellows.
