Text 19. Raphael Revealed by Raman Spectrography

Active Vocabulary:

A portrait of Madonna and the Child is one of Raphael’s most famous Renaissance creations. Now it is in a gallery in Dresden, Germany. For many years people have wondered what the provenance of the work is.

Laser Raman spectral analysis of three flecks of paint taken from the Raphael’s canvas reveals that the unknown artist used a lead-based yellow pigment called massicot (lead II oxide). This is typical of the Renaissance period and it was not used in the early 17th century. There’s historical evidence that massicot was one of the pigments used by Raphael himself.

Raman analysis is a very good technique for detecting pigments. Using scanning electron microscopy (energy dispersive x-ray microanalysis), scientists identified another yellow – lead-tin yellow – in some of Raphael’s paintings at the gallery. But it is possible that the artist was also using other yellows.

Later, as the painting has aged, a miniature sketch of the composition has become visible beneath the Madonna’s scarf. “It’s undoubtedly an original in some form,” Alan Ward said. Further research could confirm it. But it’s unlikely there will ever be conclusive proof that Raphael was the artist. “ The more evidence one gets about it, the more firm the conclusions that can be drawn,” he said.

І. Decide which of these statements are true and which are false.

1. Raphael made only one work. It is “Madonna and the Child”. 2. Using massicot was widely spread during the Renaissance period. 3. Scientists have never detected pigments yet. 4. Scientists could see nothing under the layers of paint on the portrait.

ІІ. Answer the following questions.

1. Where is the portrait of Madonna and the Child now? 2. What is massicot? 3. What did the scientists do to detect pigments? 4. What was Raphael and what do you know about him?

Text 20. How Much Arsenic do You Drink?

Active Vocabulary:

Sex, drugs, rocks, gold, murder, war, mass poisonings, the deaths of Napoleon, Tchaikovsky, Mozart, and others are all linked by one element – arsenic! Arsenic has been around since the beginning of time and the word has become a metaphor for poison with associated shock value.

But nowadays Japanese rice-based drinks are becoming a central part of Western diets, such as vegan diets. However, the levels of toxic inorganic arsenic contained in these types of drinks could, in fact, be cause for concern.

High levels of arsenic have recently been found in rice-based food. Now, researchers have found that some drinks and syrups contain high levels of arsenic too. “The rice-derived products we investigated are consumed by millions of people in Japan on a regular basis, and are increasingly becoming an important part of the diet of health conscious consumers in Western countries,” says Signes-Pastor. However, regularly including these types of drinks in the diet could add as much as 23% of the daily tolerance level of arsenic.

Although in isolation this may not seem of massive concern, for people already taking high levels of arsenic from rice and sea-weed based products this could mean exceeding maximum daily tolerance levels.

Similar products derived from barley or millet contain much lower levels of arsenic and could be used as an alternative to the rice based drinks. This could be particularly important for people who already eat a lot of rice and sea-weed products.

The experiments showed that regulations for inorganic arsenic in foodstuffs and non-water drinks should be re-examined. Regulations for arsenic in foodstuffs and non-water drinks may lead to a reduction in the incidence of arsenic-attributable diseases, including various cancers.
