This is a key element in recreating the drawing on the medieval, antique tomb of Rabenstorp in the church of St. John the Evangelist in Szczecin. "The composition of the coloring mass turned out to be unique - wood tar with the addition of crushed pyrite, similarly to the technology of its application - in the form of an emulsion!" says prof. Langer.

Coloring material has been reproduced with great precision in both chemical and microstructural aspects, bearing in mind that all applied components and operations would be available in the Middle Ages.

You can even talk about copying the original dye and technology of its use "- adds the professor. This discovery on a global scale deserves huge congratulations for the whole team.
