	The examination presented in this paper has been conducted in order to identify the drawing tools used by Szymon Czechowicz (1689‒1775) ‒ the most significant Polish painter of the late baroque period. 12 artists’ works from the collection of the Jagiellonian University Museum have been examined, using such non-invasive methods as Raman spectroscopy (RS), X-ray fluorescence (XRF), Infrared False Colour photography (IRFC), and near infrared spectroscopy (NIR). These methods allowed the analysis of the chemical composition of the drawings’ lines, as well as the identification of the drawing tools: sanguine and red pencils containing red ochre, red lead and white filling such as chalk and gypsum, sepia, graphite pencils, charcoal, and black pencils containing animal black. The materials identified are typical for the 18th century and the geographical areas of the artist activities. The results of the examination can be used as a verification criterion of the authenticity of other sketches attributed to the artist.
