Making painting with coffee is very easy and inexpensive since most homes have the raw material available, it is also a harmless product for health.
Learn how to prepare this type of paint, its peculiarities and how to create different tones according to your needs.
How to make paint with coffee
To make a painting with coffee you need:
- Coffee powder—It can be ground or soluble coffee. Some people prefer soluble coffee because it saves time in its preparation, it does not require equipment and there is direct control over the mixture.
- Hot water—To dissolve soluble coffee, the water does not need to be hot, but it makes the process easier.
- Container container for the mixture.
The only critical aspect in preparing paint with coffee is the ratio of water and coffee. The objective is to make a very strong coffee with little water in the mixture: dark, dense, elastic, with a sticky appearance.
Think that you want to achieve a brown paint with the characteristics of intensity and depth of hue and tone of a brown ink. This mixture should give you the darkest and most intense tones you can get. It is easier to start with the darkest value and lighten it later than to reverse the process.
How does coffee paint darken? Adding more coffee and reducing (evaporating) the water in the mixture if there is an excess of this.
How do you lighten the coffee paint? Adding more water to the coffee paint. How to do it is a matter of preference.
Some people prefer to have several jars prepared with different proportions of water and coffee, from darker to lighter; Others prefer to lighten the paint on the palette by adding more water with the brush.
Characteristics of coffee as paint
- Structure—Coffee as a paint has different characteristics than other water-based media with which it is often compared, such as watercolor or ink. Its structure is more dense, elastic and sticky, which determines its reaction on the support and how to work with it.
- Tone and hue—Brown monochromatic works are drawn and painted with coffee. In other words, it plays with the lightness and darkness of the tone of a brown hue that can vary slightly in hue depending on the characteristics of the coffee used.
- To provide small variations in the hue of the color (obtain a reddish brown, greenish, etc.) or darken its tone even more, watercolor or ink can be mixed with coffee.
- Drying—With regard to drying, it should be noted that coffee paint, as with watercolor, becomes considerably lighter when it dries than when it is applied wet. And, like ink, the darker its hue, the brighter its surface.
- A coffee paint takes longer to dry than a watercolor or ink and the result is always stickier. If watercolor and ink are reputed to be mediums that allow few corrections, at least coffee is more manipulable overall and for longer. You can even correct a value that is too dark with water when the stain has already dried (although it will always be easier to do it wet).
- Perdurability—As with the rest of pictorial media, it is necessary to avoid direct exposure of the finished painting to sunlight so that the color does not deteriorate. Moreover, according to the testimony of several artists who have been painting with coffee for decades and the tests of the coffee painter Steven Mikel, the durability conditions of a painting made with coffee are similar to those of a watercolor.
