loose soot into the surface and show depth of grain. Soot will not come off when touched and surface is solid. Semi-transparent finishes offer a larger pigment selection than transparent. Color will patina gradually.
• Hybrid finishes are a combination of light and drying oils, and can have a polymerized oil (alkyd urethane) component. The light oil will penetrate and show depth of grain while the reactive drying oil will remain on the surface to protect from UV and show more pigment. Pigment load is high as an effective UV inhibitor and silicone doping sheds water while allowing the wood to breathe. The color will stay consistent until the surface residue erodes off over time, then the color will begin to patina gradually.
• Unfinished Gendai will change color relatively quickly. Surface is sooty at first but will not shed much soot after washing or a first heavy rain. The light soot layer will erode slowly and the color will weather organically.
