In this study, it was aimed to investigate the effect of bleaching chemicals on color change and surface roughness of Eastern Beech (Fagus orientalis Lipsky.) wood. Bleach has been used. The bleaches used; Sodium hydroxide-hydrogen peroxide (NaOH-H2O2), oxalic acid (H2C2O4), peracetic acid (C2H4O3), peracetic acid diluted 1/3, peracedic acid diluted 1/6 by the method of application, with a brush in a way that m2 is 120 – 150 gr. has been driven. All samples were varnished with cellulosic varnish. According to industrial applications, the varnishing of the sample pieces was 120±5 g/m2 per unit area, with 2 layers of filling varnishing and 1 layer of final varnishing. After both filling and varnishing applications, the sample pieces were dried and sanding processes were carried out using aluminum oxide paper sandpapers with 1st layer 220 and 2nd layer 400 in a vibrating hand sanding machine. After the varnish applications, the cellulosic varnished parts were left to dry for 12 hours at a temperature of 20 ± 2 C degrees and a relative humidity of 65 ±5. Then, the surface roughness of the samples was determined by using a needle scanning roughness tool in accordance with the principles of DIN 4768, and the color change was determined according to the ISO/CD 5631 standard. According to the results, it was determined that all bleaching chemicals increased the surface roughness, and the highest value was found in the samples treated with peracedic acid (229.070 N/mm2) diluted at a ratio of 1/3. As for the color change, sodium hydroxide-hydrogen peroxide (23.25 N/mm2) chemicals gave the highest color change results. It can be said that the most effective bleaching agent for oriental beech wood is sodium hydroxide-hydrogen peroxide.
