Verdigris patina is a protective layer of oxidation that forms over metals like copper, brass, and bronze when exposed to air over many years. This natural process gives the metals a unique aged beauty. While artists in the past used verdigris as a pigment, modern products have been developed that can accelerate the formation of patina, allowing individuals to quickly achieve similar effects through controlled chemical reactions like using heat or acetic acid. No two patinas are exactly alike due to variations in conditions and application techniques, contributing to the charm of uniquely aged surfaces.

1. The Aged Beauty Of A Verdigris Patina

2. Metal with a verdigris patina has an aged beauty that is
unique. This protective layer of oxidation is formed over
metal like copper, brass and bronze through the years as
it is exposed to the air. Products have been developed
today that can speed up this natural process. These
chemical solutions are able to add patinas to surfaces
quickly and efficiently.

3. Artists long ago made use of the vibrant green of
verdigris to make pigment for their paintings. Copper
plates were placed in a pot of hot vinegar and the green
crust that formed was scraped off for making of
pigment. However, this pigment was unstable and it fell
out of use when more stable pigments were developed.

4. Faux painting techniques allow individuals to recreate
the effect of aging. However, the true finish is hard to
imitate and is only produced when metals are oxidized.
This chemical process is accelerated in several different
ways. Using a source of heat, like a blowtorch, can
create an interesting mix of blue and green patinas.
Distilled vinegar or acetic acid produces a pretty green
color as copper acetate is formed.

5. The process of oxidation is an organic one and no two
patinas look exactly alike. Variations occur in the
chemical reaction according to conditions under which it
takes place and the techniques used. This is part of the
charm as each object looks different.

6. One of the great attractions of this aged finish is the fact
that each surface is unique. The type of metal and the
amount of time it has been exposed contribute to the
variations. If this look is created by using one of the
products on the market, it does not take away from this
uniqueness as each object treated will still have
variations. It is not like choosing a particular color of
paint and applying it.

7. Today there are many products that can speed up the
process of creating genuine patinas. These are available
at both local and online stores. They are easy to apply
and clear instructions are given on usage. The surface
has to be thoroughly cleaned before applying any of
these products as even grease from fingers can affect
the result.

8. Various different applicators may be used to apply these
products such as sponges, brushes, rags and sprayers.
Trial applications are recommended. One can
experiment with many different objects and surfaces. It
is often better to use more thin coats than fewer thick
coats as one has more control of the effect created.

9. As with any product using chemicals, care needs to be
exercised when using these products. However, as long
as instructions are followed carefully, there should be no
problem. A tip is to always pour product into a
disposable container for use so that one does not have
to dip an applicator into the bottle.

10. A verdigris patina is extremely popular today. Objects
are aged to provide a contrast with contemporary
materials used, creating an eclectic look and introducing
a sense of history and interest. Products are available at
local and online stores that can help one create genuine
patinas as quickly and efficiently as possible.
