However, elevated temperatures may pose a risk of damaging surface coatings used on cultural and historical artefacts. Therefore, we monitored changes in patterns of the original paint taken from such objects along with newly prepared coatings. We evaluated visual, mechanical, and chemical modifications of coatings when exposed to microwaves (750W, 2.4GHz), at 60°C or 80°C for 10 min. Whether old or new, only water-based coatings have proven to be resistant to elevated temperatures and no damage was observed at 80°C. Blisters have formed on layers of new oil paints and natural resins due to insufficiently cured film. Temperatures above 80°C may cause melting of coniferous wood resin and thus transport of resin to the surface; on the other hand, temperatures up to 60°C are completely harmless. Mechanical and chemical changes of coatings exposed to microwaves were not observed, but the studies showed that colour and gloss exhibited minor changes</dc:description><dc:description xml:lang="sl">Mikrovalovi so zelo učinkoviti pri zatiranju lesnih škodljivcev. Lahko pa povišane temperature pomenijo tveganje za nastanek poškodb površinskih premazov, uporabljenih na kulturnozgodovinskih predmetih. Zato smo spremembe spremljali na vzorcih originalnih premazov, odvzetih s kulturnozgodovinskih predmetov, ter na novo pripravljenih premazih. Ocenili smo vizualne, mehanske in kemične spremembe premazov, izpostavljenih mikrovalovom (750W, 2,4 GHz) pri 60 °C ali 80 °C za 10 min. Stari premazi in novi, a le tisti na vodni osnovi, so se izkazali odpornejši proti povišanim temperaturam in poškodb pri 80 °C nismo opazili. Poškodbe v obliki mehurjenja so nastajale pri slojih nove oljne barve in naravnih smol, kot posledica premalo utrjenega filma. Temperatura nad 80 °C lahko povzroči taljenje smole v lesu iglavcev in tako prodiranje na površino vzorca pod premaz, medtem ko so temperature do 60 °C povsem neškodljive. Mehanskih in kemičnih sprememb premazov, izpostavljenih mikrovalovom, raziskave niso pokazale, sta pa se minimalno spremenila barva in sijaj</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-QK6CQILG"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-QK6CQILG" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-QK6CQILG/cf125f84-53e3-4346-af10-fe329365363d/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Gozdarski inštitut Slovenije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-QK6CQILG/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-QK6CQILG" /></ore:Aggregation></rdf:RDF>
