Abstract
Z ustrezno zaščito lesenim izdelkom v uporabi občutno podaljšamo življenjsko dobo. Za površinsko obdelavo lesenega nakita je zelo pomembna pravilna izbira premaznega sredstva, trendi se pa na vseh področjih nagibajo v okoljsko sprejemljive rešitve. Z uporabo naravnih olj bi s tem zadovoljili okoljske zahteve, morali pa smo ugotoviti, katero olje bi bilo za ta namen najprimernejše. Izbrali smo pet naravnih olj: laneno, orehovo, konopljino, kokosovo in tungovo olje ter komercialno olje »decking« za primerjavo. Na vzorcih bukovine smo spremljali navzem olja, hitrost vpijanja olja in vode, stopnjo utrjenosti, spremembo barve in sijaja ter odpornost proti hladnim tekočinam in suhi toploti. Če izvzamemo olje »decking«, je imelo najmanjši navzem tungovo olje, prav tako so vzorci, obdelani s tem oljem, dosegli najboljše rezultate pri hitrosti vpijanja olja in vode ter pri stopnji utrjenosti. Barvo neobdelane površine je najmanj spremenilo laneno olje, po enem letu pa se je barva oljene površine najmanj spremenila pri konopljinem olju. Proti hladnim tekočinam in suhi toploti je bilo tungovo olje celo bolj odporno kot komercialno olje »decking«. Kokosovo je bilo izločeno zaradi tvorbe filma na lisasti površini. Izdelovalec lesenega nakita se naj sam odloči, kateri lastnosti bo pripisal večji pomen, pri tem pa si lahko pomaga s predstavljenimi rezultati.

Title:AN ESTIMATION OF SUITABILITY OF DIFFERENT NATURAL OILS FOR SURFACE TREATMENT OF WOODEN JEWELLERY
Abstract:
The life span of wooden products can be increased significantly by proper protection. For the surface treatment of wooden jewellery, it is of great importance to choose the right coating. As ecological awareness is gaining traction, the solution might lie in the use of natural oils as coatings. Thus, it was only sensible to examine which natural oil would be the most suitable as surface protection for wooden jewellery. We chose to test five natural oils: linseed, hemp, walnut, coconut and tung oil and a commercial, »decking« oil, for comparison. The oils were tested on beech wood for the following properties: oil uptake, absorption of oil and water, drying behaviour, change of colour and gloss and resistance to cold liquids and dry heat. If we only take into account natural oils without the »decking« oil, the best results were observed as follows: oil uptake, absorption of oil and water, drying behaviour were the best in the case of tung oil. Coconut oil was excluded due to the unpleasant aesthetic changes it had caused on the treated surface. Linseed oil caused the least change of colour to the untreated surface, while the colour of the surface treated with hemp oil changed the least in the period of a year. The best resistance to cold liquids and dry heat was observed with tung oil. The manufacturers should choose by themselves which oil meets their specific needs and the findings in this work may be of help.
