The Christie, Manson and Woods sale of Marochetti's studio contents, held on 7 May 1868, included "Lot 127, Bas-relief profile of the late Lord Macaulay, in Minton's ware." This suggests that the profile relief of Macaulay, which is known in casts in bronze, signed and dated 1848, was also issued in ceramic form by the firm of Minton, though no example of this version of it has yet come to light. A Parian Ware relief portrait of James Oswald M.P. byy Marochetti, signed and dated 1849, does exist in a French private collection, and this, together with the relief of Macaulay may have been part of an experimental project by Minton. Such reliefs are nowhere mentioned in the literature on the firm or in the contemporary press. Furthermore, portrait reliefs are a rarity in Parian Ware and Statuary Porcelain, the only other recorded example being Shakespere Wood's 1847 relief of Jabez Bunting, the popular preacher, issued by Copeland. Difficult to explain why this would have been so, since, manufacturing such reliefs would not have been problematic from a technical point of view. The lack of any reference to Marochetti Parian relief portraits is a mystery still awaiting solution.
