Occasionally, especially if the mixture has been left for many days there will be cuprous oxide (CuO) present, as the copper will react with water. This can muddy the colour of the verdigris as it is a yellow to red colour. The good news is that it can be solved by adding water to the mixture as the copper oxide will not dissolve but the verdigris will and so can be separated by filtration or decanting. This cuprous oxide tends to be a yellow colour when in a very fine powder, but if the crystals are larger it will appear more red. Once separated from the verdigris it can be used as a pigment in its own right or can be used for its anti-fungal properties.

Substances reflecting light between 475-590 nm Green Malachite mineral mixed with blue Azurite Verdigris pigment Like nearly all other ancient Greek science-artists, you have seen and heard how corroded copper, and its alloys, are an interesting shade of green. Some artists have even started using this verdigris copper as the pigment in their paints. However, you have noticed that there are definite differences in colour between the paint pigments, despite being created from the same material. a b c d e f Benhamou, Reed (1984).

Step 3 – Mix the powder and medium together well. And voila! You have just made your own DIY Patina Paint! Pretty easy, huh? I like verdigris, and all these greenish, eggy blues, because it reminds me that Tiffany doesn’t own turquoise. Neither do the mine owners in Colorado who are trying to brand their turquoise, nor does the silver company that bought up all the stones from a single town. You can own a stone and you can patent a color, but you can’t own the word or the meaning. The minute you try, you lose something. a b Anant, Jagdish Kumar, S. R. Inchulkar, and Sangeeta Bhagat (2018). "An overview of copper toxicity relevance to public health." EJPMR 5, no. 11: 236. It’s hard to imagine now, but people once gathered together freely, shoulders rubbing against shoulders, breath exchanged between lungs, bodies open to one another—all this closeness, almost a million people standing in a crowd just to watch a statue get undressed. Varichon, Anne (2005). Couleurs: pigments et teintures dans les mains des peuples (in French). Paris: Editions du Seuil. ISBN 978-2-02-084697-4.Green pigments are the materials used to create the green colors seen in painting and the other arts. Most come from minerals, particularly those containing compounds of copper. Green pigments reflect the green portions of the spectrum of visible light, and absorb the others. Important green pigments in art history include Malachite and Verdigris, found in tomb paintings in Ancient Egypt, and the Green earth pigments popular in the Middle Ages. [1] More recent greens, such as Cobalt Green, are largely synthetic, made in laboratories and factories. Copper domes and copper covered roofs are often green in colour because chemicals in the air from the burning of fossil fuels react in different ways with the copper.

In a wet environment the copper (I) chloride crust reacts with the water to produce copper(I) oxide (Cu2O) and hydrochloric acid. The hydrochloric acid produced will go on to react with more copper to produce additional nantokite. CuCl(s) Once you remove the copper you will be left will be left with the verdigris dissolved in water. You could use it as it is as a dye however it is very dilute. I left mine on a radiator with no lid for about two days to fully evaporate.
