The Reckitts chimney stands 141m tall. Located on Morley Street in Hull, it’s where Reckitts, in 1884, began making synthetic ultramarine (often known as dolly blue). Used as a laundry product, ultramarine prevents the yellowing of white fabric when it is washed and enhances the brightness of colours. It is now widely used in the cosmetics, paints and automobile industries.
Natural ultramarine was derived from ground lapis lazuli, sourced in the mountains of Afghanistan. Artists reserved the use of this expensive bright blue pigment for their most important (usually religious) works. Cennino Cennini (b. c.1370 – c. 1440) described it as “illustrious, beautiful, and most perfect, beyond all other colors”. Vermeer used natural ultramarine extensively (Woman in Blue Reading a Letter, 1663-1664). In 1828, the French chemist Jean-Baptiste Guimet developed a synthetic equivalent, which was used for example by Renoir (Les Parapluies, c. 1880), Monet (Gare St Lazare, 1877) and Pissarro (La Côte des boeufs, 1877).
For decades, the chimney pumped sulphur dioxide into Hull’s atmosphere. My grandparents lived in Stoneferry, the area in which this factory was located. I remember the sweet smells drifting from the cocoa processing plant on Cleveland Street and the hot metallic tang of the factories by the river.
