A fine pair of George III Ormolu mounted Blue John perfume burners, standing on white marble bases, below Blue John shaped urns mounted with ormolu swags.
Boulton’s family originally produced silver toys, he even managed to establish an Assay office in Birmingham after petitioning in parliament, much to the chagrin of the London Goldsmiths. In the 1770s Matthew Boulton started making Ormolu (originally a French speciality) vases inspired by classical Greek works. Among his clientele was Catherine the Great and Queen Charlotte, wife of George III.
The pattern for the base of these perfume burners appear in at least four designs from Boulton’s metal work pattern book that is preserved in the Birmingham city museum.
Another pair of this classic form of burners is in the connection at Harewood House, Yorkshire.
