From the history of invisible inks

From the earliest times people was interested in the possibility of secret information transfer. Today together with great achievements of science and technique there are a lot of ways of exchanging and protection of important data. But at the same time, the invisible ink is continuing to be widely used both in our day-to-day life and in printing of serious information.

For the first time ever the invisible inks were mentioned in the notes of Philon Alexandreos (1 century CE). He described a method of writing with the help of oak galls juice and the following text development after the treatment with iron and copper salts. One method of cryptography with smut and milk usage is also known. It was recommended to lovers by Ovidius, who was a known poet in ancient Rome. On the sheet with a secret message, which was written with milk, the smut was applied. After it was blowing away the small parts were stuck only to letters. In the same way the moisture of plants were used, the references about this were made in Natural history.

In mediaeval Europe this type of ink was widely used by con-men, who showed to ignorant people miracles of unexpected appearing. Later the invisible ink became widely used in many countries for secret diplomatic correspondence delivery. The invisible ink was also popular in the middle Ages. So, Russian revolutionists wrote their messages between strings with milk and in such a way they send messages from prisons.

For the first time the definition for invisible ink as sympathetic ink was introduced by French chemist N. Lemery in 1675 in his Cours de Chymie - "Chemistry course". This book had a great success and since then this name has been firmly fixed to the secret ink. During the Second World War the composition of sympathetic ink was changing permanently. It became more complicated and it was difficult to find it out.

There are many kinds of sympathetic inks, which are classified according to teir different parameters. The color after development, the way of their revealing or the ink nature, which depends on their structure, could be as a determinant attribute. This ink played an important part in the actions of politicians and spies all over the world, as well as of average citizens, who needed to send messages secretly.

The structure of invisible ink

The manufacturing of invisible ink has been started a long time ago. There are a lot of agents, which were used for their preparation. Million people applied different methods of cryptogram. One of them just used milk for that; others applied different complicated chemical compounds. But all of them tried to find out a reliable way of information protection. Since the First World War chemists have been working with invisible inks formula. They improved and variegated inks greatly. The composition of up-to-date invisible inks could differ essentially and as a rule, they have colorless or light colored agents in their structure, which could react with other reagents and make vividly colored products. As the main components such chemicals as different acids, salts as well as edible solutions, moisture of plants and other reagents could be used. Everything depends on chemists and manufacturers professionalism.

Interestingly, a famous spy Mata Hari also used invisible ink in her activity. During her caption in Paris a bottle of cobaltous chloride solution was found. This fact aroused suspicions and acted as a motive for her uncovering. Cobaltous chloride has interesting characteristics and it could be successfully used in cryptogram. The text, which was written with such solution will be absolutely invisible and will appear if heating slightly.

Not long ago, American researchers from the Michiganian University found out another secret of writing with invisible ink. It was widely used by German intelligence agency. They placed a sheet of paper, which was saturated with cerous oxalate, between clean sheets. After that they wrote a message on the upper sheet, which printed on the lower sheet. This text developed after the processing of the paper with magnesium sulfate, peroxide solution or other additional reagents. As a result, an orange text appeared. During the Second World War soldiers used many other reagents for secret information delivery, among which the most widespread was copper sulfate, which was developed after sodium iodide treatment, iron sulfate and chloride of sodium, which developed after interacting with caustic silver.
