How finish protects and also changes color
A finish slows water and dirt at the surface, and the same coat darkens and warms the wood.
When the purchase is complete, return to the original window. It will refresh.
From the opening
A finish is oil, wax, shellac, varnish, lacquer, or paint occupying the surface of wood so liquid water, dirt, and handling meet the coating first. The same material changes the color, because it fills the surface and filters the light that used to scatter off bare fibers. The opening covers wetting deepens the dry color, oils and varnishes add amber, and a film blocks liquid water.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
