Wax was applied to wooden material surfaces using a brush in one, two, and three layers. Tests were then conducted on surfaces with and without wax. The results were statistically significant according to the multivariate variance analysis. It was determined that the application of wax led to a decrease in L*, h°, and WI* values on the wooden material surfaces (parallel and perpendicular to the fibres), while the a*, b*, and C* parameters increased. In measurements parallel and perpendicular to the fibres, increases were observed in gloss values for two- and three-layer wax applications at 60° and 85°. The ?L* values were negative when wax was applied in one, two, and three layers, whereas the ?a*, ?b*, and ?C* values were positive. The ?E* values were determined as 8.41 for one layer of wax, 11.29 for two layers, and 11.59 for three layers. Given the similarity between the ?E* values of two and three layers of wax, it can be inferred that a third layer may not be necessaryProučevali smo vpliv nanosa voska na barvo, sijaj in indeks beline (WI*) lesa ameriške čremse (Prunus serotina Ehrh.). Vosek je bil nanesen na površine lesa s čopičem v enem, dveh in treh slojih. Teste smo opravili na premazanih in nepremazanih površinah. Analiza variance je pokazala statistično značilne razlike v rezultatih. Medtem ko smo po nanosu voska opazili zmanjšanje vrednosti L*, h° in WI* v smereh vzporedno in pravokotno na vlakna, smo ugotovili, da so parametri a*, b* in C* po nanosu narasli. Pri merjenju sijaja pri 60 in 85 stopinjah smo pri vzorcih z dvema in tremi plastmi voska opazili povečanje vrednosti pri merjenju vzporedno in pravokotno glede na smer lesnih vlaken. Vrednosti ?L* so bile negativne za voskane sisteme, nanesene v 1, 2 in 3 slojih, medtem ko so bile vrednosti ?a*, ?b* in ?C* pozitivne. Vrednost ?E* je po 1-slojnem voskanju znašala 8,41, pri 2-slojnem 11,29 in pri 3-slojnem 11,59. Glede na to, da so bile vrednosti ?E* po 2 in 3 nanosih voska podobne, lahko sklepamo, da 3. nanos voska ni potrebenTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza lesarjev Slovenije
