Introduction

Masterminds & Masterpieces – An interactive lesson in which students discover how conservators use x-rays to study paintings by Vincent van Gogh. The lesson is suitable for independent study, or whole-class teaching.

Instructions

General learning objectives

• Students learn what x-rays are

• Students get to know Vincent van Gogh

• Students see how a conservator uses x-rays to examine paintings

A curious and inquiring mind is vital for the preservation and conservation of art, and for science and technology in general. This lesson is part of the Masterminds & Masterpieces series, that uses the interdisciplinary benefits of inquiry-based learning (experimenting, trying out, looking, comparing, etc.). Masterminds & Masterpieces is a collaboration between the Van Gogh Museum and ASML.

Link to curriculum

This lesson ties in with the subjects art, physics and science.

Additional preparation

If the students aren’t quite sure who Vincent van Gogh was, watch the video Who was Vincent van Gogh?

Variation

• This lesson can be combined with the lessons on UV – Van Gogh’s enemy / friend, and with the lesson on infrared radiation.
• For students who can handle slightly more difficult material, the related lessons for higher-level students can be used.

What are you going to learn today?

In this lesson you will learn:<div><div><ul><li>what <b>x-rays</b> are</li><li>what a <b>conservator</b> does</li><li>who <b>Vincent van Gogh</b> was</li></ul></div><div>And you will see how x-rays can help the conservator get a closer look at Vincent’s paintings.</div></div>

So, x-rays?

They are what doctors use at the hospital to see if you have broken your arm or leg. But why do people use them on paintings too?

What’s happening here?

A <b>conservator</b> is looking at x-rays of a painting by Vincent van Gogh:&nbsp;<i>Horse Chestnut Tree in Blossom</i>

So what does a conservator do?

A conservator keeps a check on and looks after works of art or old objects in the museum, and repairs them if they are broken or damaged. It’s a very important job! At the Van Gogh Museum we take good care of the work of Vincent van Gogh, so that people can keep coming to see it in the future.

Vincent van Gogh

Vincent van Gogh
<div><ul><li>lived from 1853 to 1890</li><li>grew up in the Netherlands</li><li>lived in four countries (Netherlands, Britain, Belgium and France)</li><li>decided to be an artist when he was 27</li><li>made almost 900 paintings, over 1000 drawings and wrote hundreds of letters</li><li>was not famous during his life</li><li>is now a very famous artist</li></ul></div>

Invisible...

You can’t see x-rays, just like you can’t see infrared (IR) or ultraviolet (UV) light.

What can you do with x-rays?

You can use <b>x-rays</b> to see something that you can’t see just with your eyes. You can take a picture of your bones, for example, like you’re looking straight through your skin. X-rays go through skin very easily, but they don’t go through bone so easily. You need a special machine to make x-rays.

Who’s this scary guy?

This is part of a painting called <i>Head of a Skeleton with a Burning Cigarette</i>&nbsp;which Vincent painted in 1886.<div>X-rays had not been invented then, so Vincent used a real skeleton as his model.</div>

Wilhelm Conrad Röntgen discovered x-rays in 1895 – five years after Van Gogh died. So Vincent had never heard of them.

How do you use x-rays to inspect a painting?

Watch the video on the next slide to find out.

A painting of a place in the countryside is usually called a <b>landscape</b>. If it is of something in a town or city, it is a <b>cityscape</b> or <b>urban landscape</b>. A painting of a face is a <b>portrait</b> or <b>self-portrait</b>.

X-rays help us to inspect
paintings because you can
use them to...

1. measure how big the painting is
2. discover paintings underneath
3. see invisible cracks and holes
4. see all the different layers of paint

You can choose more than one answer!

 Drag the words to the right boxes

... easily let(s)<div>x-rays through</div>

... do(es) not let<div>x-rays through at all, or not easily</div>

Your bones

A nail

You can’t see the patches
in the circle with just your eyes.
What do they tell us?

Discuss the pupils’ answers. Use the pencil function to write keywords on the board. If some of the kids have smartphones, switch on ‘devices’.

It’s sometimes difficult
to understand an x-ray
of a painting.
Do you know why?

1. It only shows the green paint
2. The nails make it difficult to keep your mind on the painting
3. You see all the layers of paint on top of each other
4. You need special glasses

... that a storm makes visible light (lightning) and invisible x-rays? Nature doesn’t need a machine for it...

... that x-rays are used in industry too? You can use them to see if there are any mistakes in a weld that holds two pieces of metal together. Then you know if it’s strong enough.

Did you know...

Now you know:

<ul><li>who Vincent van Gogh is</li><li>that x-rays are not only used in hospitals
</li><li>that a painting has more than one layer
</li><li>that you can look under the top layer of paint using x-rays
</li><li>that you can discover old layers of paint using x-rays</li></ul>
