A
(2024·扬州二模)Beer and eggs are commonly seen in the kitchen. However, scientists recently found that they were used in historic paintings too.
To preserve(保存)Danish paintings, a group of researchers studied what ancient paint was made of. They did experiments on small pieces of paintings that had already been cut off from the original artwork.
According to their paper published in Science Advances, grains(谷物)and yeast(酵母)were found on the base of the paintings. Beer was the most common drink in the 19th century in Denmark, and its by-products were spent grains and yeast.
The study showed that they were used to provide a stable painting surface. Researchers also pointed out that one beer by-product was used as “glue” because it had a lot of sugar. With beer added, the paint can also dry faster.
Apart from beer, the egg has long been found in oil-based paints used by artists in the 15th century, such as Italian painter Leonardo da Vinci. A recent study published in Nature Communications may have “cracked” the secret of how eggs can help preserve artworks.
The researchers recreated the ancient paint by adding egg yolks(蛋黄)to oil paint. They then looked into how it changed over time. The findings showed that the yolk’s proteins helped slow the oxidation(氧化)of the paint. It could also reduce wrinkling(褶皱)as the egg makes the paint more smooth.
However, the oil paint with added egg usually takes longer to dry. It seemed fine for artists—they were willing to accept to have their work preserved for longer.
“The more we understand how artists choose and use their materials, the more we can appreciate(欣赏)what they’re doing,” Ken Sutherland, an expert at the Art Institute of Chicago, the US, told Science News. Sutherland added that research like this could help people have a deeper understanding of the artworks.
1. Why were beer by-products used in historic Danish paintings?
A. To help the colours stick better.
B. To keep the paintings clean.
C. To make the paintings more colourful.
D. To give the painting a different feel.
2. What does the underlined word “cracked” in Paragraph 5 probably mean?
A. Kept. B. Shared.
C. Discovered. D. Explored.
3. How could egg yolk proteins change the paint?
A. The paint could age faster.
B. The paint could dry more quickly.
C. The paint’s colours could be nicer.
D. The paint could feel smoother.
4. From Sutherland’s words, we can know that ______.
A. it’s easy to appreciate artworks in the right methods
B. it’s important to understand the minds of artists
C. it’s hard to research early artworks
D. it’s necessary to help people understand artworks
