FTIR analysis of the flesh from the Madonna from the church St. Thomas in Brno. Infrared spectrum of the first layer (incarnate) of the sample embedded into the Polylite (red spectrum) together with the infrared spectrum of Polylite resin (blue spectrum), the infiltration of Polylite into the sample is evident. In the infrared spectrum of the same first layer (incarnate) of the sample pressed in the KBr (pink spectrum) the vibrational bands of albumen (dark blue spectrum), linseed oil (green spectrum), white lead (yellow spectrum) and chalk (violet spectrum) can be recognized.
