Abstract
V sodelovanju z Gorenjskim muzejem Kranj smo raziskali 24 pravoslavnih ikon za katere muzej ni imel nobenih podatkov o starosti in izvoru. Cilji raziskave so bili ugotoviti lesno vrsto posamezne ikone, popisati posebnosti in napake lesa, opraviti dendrokronološko analizo pri ikonah, ki so imele več kot 50 branik, oceniti ohranjenost lesa ter podati napotke za ohranitev lesa. V muzeju smo ikone pregledali makroskopsko, opravili meritve širin branik, ikone fotografirali ter odvzeli vzorce za mikroskopsko identifikacijo lesa, ki smo jo opravili na Oddelku za lesarstvo. Ikone so bile narejene iz 8 različnih lesnih vrst. Pri 10 ikonah je bila osnovna deska iz smrekovine, pri 6 iz orehovine, pri po 2 iz lesa jelke, ciprese in domačega kostanja, po 1 ikona pa je bila izdelana iz lesa bora in bresta. Pri 1 ikoni je bil križ narejen iz smrekovine, pri 1 pa je bila letev iz lesa topola. Nekatere ikone so vsebovale manjše napake, kot so stržen v deski, kolaps, poranitveni les ter manjše grče. Opazili smo tudi prisotnost juvenilnega lesa, ki povzroča večje krčenje in nabrekanje, ter večje grče, ki neugodno vplivajo na videz poslikane strani. Poškodbe insektov smo opazili pri 7 ikonah, gliva pa je poškodovala 1 ikono. Širine branik smo izmerili pri 4 ikonah iz lesa smreke in pri 1 iz lesa rdečega oz. črnega bora; vse so imele več kot 50 branik. Dendrokronološko datiranje ni bilo uspešno zaradi pomanjkanja ustreznih referenčnih kronologij iz jugovzhodne Evrope, od koder najverjetneje izvirajo proučene ikone.

Abstract:
In collaboration with the Museum of Kranj we studied the wood of 24 Orthodox icons for unknown age and origin. The objectives of this study were to identify the wood species, to survey the characteristics and defects of the wood, and to perform dendrochronological analysis on the icons containing more than 50 tree-rings. We also assessed the state of wood preservation and provided suggestions for its conservation. Macroscopic wood identification and tree-ring measurements were performed in the museum; the photos of the icons were taken there also. Microscopic wood identification was carried out at the Department of Wood Science and technology. The icons were made of 8 different wood species. 10 of them were made from Norway spruce, 6 of walnut, 2 of fir, cypress and sweet chestnut, and 1 of pine and elm. 1 cross was made of spruce and one horizontal bar of poplar. Some of the icons contained minor defects like the presence of pith, local collapse of wood, wound-wood and smaller knots. Juvenile wood, which causes greater shrinkage and swelling, has been observed as well. Larger knots affecting the appearance of the painted side of the icon were also found. Insect damage was detected in 7 icons and that of fungi in 1. Tree-ring widths were measured in 4 icons made of spruce wood and in 1 made of Scots pine or black pine; they all contained more than 50 tree-rings. Dendrochronological dating was not successful due to the lack of appropriate reference chronologies for SE Europe, the area from which the icons probably originate.
