Abstract

Linden wood is used in match production, double bass making, carving, musical instrument crafting, and furniture production. This study examined the effects of applying varying numbers of wax coats (1, 2, and 3 coats) on the color parameters, glossiness values, and whiteness index (WI*) values of linden (Tilia tomentosa Moench.) wood surfaces. A comparison was made between untreated surfaces and those treated with three different wax applications. According to the obtained results, all tests except for hue angle were found to be significant in the analysis of variance. The ∆E* values were found to be 5.13 for the application of 1 coat of wax, 6.53 for the application of 2 coats of wax, and 6.95 for the application of 3 coats of wax. After applying waxes to the wood, reductions were noted in WI* and L* values, while enhancements were detected in glossiness readings at 60 and 85 degrees, as well as in a*, C*, ho, and b*values.

Abstract

In this study, some surface changes (color parameters, whiteness index (WI*), and glossiness) occurring after the application of single [oxalic acid (C2H2O4)] and double component [sodium hydroxide (NaOH) + hydrogen peroxide (H2O2)] wood bleaching chemicals on naga (Brachystegia cynometroides) wood were investigated. The bleached surfaces were compared with the unbleached surfaces. According to the obtained results, the ∆E* values were determined as 2.99 for C2H2O4 chemical and 16.95 for NaOH + H2O2 chemical. Significant results were found for all tests in the analysis of variance. Increases in b* and C* values were observed with C2H2O4, while decreases were observed with NaOH + H2O2 chemical. With both wood bleaching chemicals, increases were found in WI* values in parallel directions to the fibers, as well as in ho and L* values, while decreases were obtained in glossiness values at 60 and 85 degrees in both parallel and perpendicular directions to the fibers, and in a* values.
