<p>Four different painted beehive panels dating from the beginning of the 19th to the second half of the<br>
20th century were selected for this study. This type of paintings was predominantly created by the lower<br>
(rural) classes and as such represents a variety of folk art [1]. This panels were traditionally placed on the<br>
front side of the hives. They were exposed outdoors, subjected to exterior environmental factors and<br>
therefore experienced degradation, which resulted in fading, loss of paint strata, etc. Although beehive<br>
panel paintings are specific and unique for Slovene ethnic territory, in-depth analytical studies regarding<br>
their material composition has not yet been published.<br>
Due to restrictions of the sampling, majority of the investigation on material composition within this<br>
study was performed in a non-invasive manner utilising reflection infrared and Raman spectroscopy. For a<br>
more detailed investigation micro-transflection FTIR spectroscopy on a diamond-coated metallic stick was<br>
employed on several areas of the paintings. On two panels, where sampling was allowed, we performed a<br>
more detailed study on samples’ cross-sections, which contained all stratigraphically present layers<br>
(wooden support, decorative layers). Paint layers are composed of historically commonly available<br>
pigments such as iron oxides, cinnabar/vermilion, lead white, carbon-based black, Prussian blue, etc. The<br>
main binder was determined to be composed of lipids which correspond with written archive texts stating<br>
that this type of paintings was usually done in oil. Two of the panels were also coated with a triterpenic<br>
resin. The main differences in the composition were observed for the panel from second half of the<br>
20th century, where the presence of synthetic organic red pigment PR3 and zinc white was determined.<br>
Furthermore, the presence of beeswax at the back of the panels was also detected, as well as some of the<br>
degradation products, such as carboxylates and oxalates.</p>
