Carl Scheele had successfully created a green colourant which bore his name, a realistic representation of the colour so abundant in nature, which had hitherto been so difficult to replicate. Scheele’s Green was adopted in earnest by the followers of the Romantic movement who sought to bring a splash of nature into their living rooms. Green wallpaper became fashionable, patterned with images of stylised vines and green foliage.
One who rose to prominence on the wave of this desire for floral patterned wallpaper was William Morris. Despite being a passionate campaigner for safer working conditions for textile workers and strongly supporting the use of organic dyes such as cochineal, kermes, and rose madder, he found that there was nothing that came close to matching the vibrant greens found in nature than Scheele’s Green, which he used alongside Paris green, a similar shade that was more lightfast. The problem, of course, was that Scheele’s Green contained arsenic, a lot of it.
Unsurprisingly perhaps, green wallpaper was found to be good at keeping vermin and insects away, but as the wallpaper flaked, particles of arsenic would fill the air and be breathed in by the unsuspecting residents. There were reports of children dying after their rooms had been painted a vibrant green, of decorators having convulsions, and a cat developing strange blisters after being locked in a green-papered room.
The bedroom on St Helena in which Napoleon Bonaparte spent his final years in exile was decorated with a white, gold, and green wallpaper, which was subjected to a chemical analysis in 1980 and found to contain arsenic. On his death in 1821 locks of his hair were sold to supporters and these were found to contain arsenic. The theory developed that the humid air of the tropical air caused a mould to develop, which reacted with the wallpaper creating a poisonous gas, but it is now thought that it might have contributed to napoleon’s death it was not the direct cause.
Perhaps conflicted by the fact that he was the heir to a copper mine which produced arsenic dust as a byproduct of the mining activity, Morris was sceptical of claims that arsenic was inimical to human health and well-being, decrying miners suffering from arsenic poisoning as being “bitten by witch fever”. After all, no one had died, let alone fallen sick. It was only in 1870, bowing to public pressure, that he began using arsenic-free greens in his workshop.
By the time governments in the Western world began to regulate the use of arsenic, green wallpaper had become passé, women’s clothing became more streamlined and the elaborate designs and decorations so popular in the late Victorian period were now viewed as fussy and old-fashioned. Even the demand for artificial flowers waned, the industry further handicapped by legislation prohibiting the use of child labour and the flood of cheap imports. David Bloor was probably London’s last flower maker.
Even today, green is a difficult colour to replicate. Commercial greens are often made with pigment green 7, which contains chlorine and cannot be recycled or composted safely, while pigment green 36 also contains chlorine and bromide bombs. The inorganic pigment green 50 is a noxious mix of cobalt, titanium, nickel, and zinc oxide. The irony is that green can never be green, whatever it is dyed on to contaminates it, perhaps proving once and for all that nature can never be truly replicated.
