So what is VerdigrisVerdigris is a natural patina that makes copper turn into a greenish or turquoise colour, with a slightly dusty matt effect. It happens when copper is exposed to the elements – as you can see from many cupolas and weathervanes that are old. Also old vintage jewellery can have this green colour tinge to it, however this is not a good thing.... as it is actually deteriorating the metals.
The name verdigris comes from the Middle English vertegrez , from the Old French verte grez, an alteration of vert-de-Grèce ("green of Greece"). The modern French spelling of this word is vert-de-gris. Since it was used as a pigment in paintings and other art objects (as green color), it was required by artists in Greece.
It was originally made by hanging copper plates over hot vinegar in a sealed pot until a green crust formed on the copper.
Another method of obtaining verdigris pigment, used in the Middle Ages, was to attach copper strips to a wooden block with acetic acid, then bury the sealed block in dung. Hmmm lovely!!
Anyway there are a number of ways to achieve a verdigris effect – the easiest is to just buy a verdigris effect kit or a patina kit. These usually consist of a bronze or copper paint and an oxidiser – usually acetic acid based. We have the Ranger Perfect Pearls Kit Aged Patina Kit in the store here,
