You probably think: the …. what? Well, I did. I know nothing about chemistry, so I had to do some homework. My friend, for who I made the paintings you saw in my blog ‘bright colours part 2‘ earlier, is a professor and we were invited for his oration at the University of Utrecht. And what kind of present do you give at such occassions? So I decided to make paintings for him about his specialism: depletion interaction of colloids.
Because I am not a scientist I can explain very simple what it means (if I understood it well): if you extract (depletion) certian colloids from a suspension and other colloids remain, you can change the stability and form of the substance. For example think about cheese: if you extract whey from milk, you get cheese.
So I sought all kinds of pictures of colloids, but no coloured pictures to be found online. All black and white. So I used the colours I decided to use more. I practiced on a piece of paper which combinations were the best. I chose to make circles, triangles, dots, squares and cilinders (see the picture on the left), because I saw them on the Internet als shapes of colloids. That part is realistic.
But in deciding how the shapes would be placed in the painting, I took some liberty. I chose a repititive pattern of two shapes and by leaving one of the shapes away, the other shapes clit to one another forming another substance. Finally, when I painted the 5th painting, I decided to paint the colloids in a spiral, inspired by my Nautilus project.
This is how I explained the text about the subject I found, I hope it matches the reality enough for my friend to recognize I meant to paint depletion interaction, LOL.
In this animation you can see ‘the making of’.
All the paintings are 30×40 cm and made with acrylic paint on canvas.
