Why does the original wood become darker after being used for a period of time?
Wood darkens over time due to a combination of factors, primarily exposure to light (both natural and artificial UV) and oxidation of natural wood components like tannins. These processes can alter the chemical structure of the wood, leading to a darkening effect.

Here's a more detailed explanation:
Oxidation:
Wood contains natural compounds like tannins, which react with oxygen in the air, especially when exposed to light. This oxidation process can cause the wood to darken.
UV Light:
Ultraviolet (UV) radiation from sunlight and artificial light sources can also accelerate the oxidation process and contribute to the darkening of wood.
Chemical Changes:
The resins and other chemical components within the wood can also undergo changes over time due to exposure to light and air, leading to a shift in color.
Specific Woods:
Some wood species are more prone to darkening than others. For example, cherry wood is known to darken significantly over time due to oxidation.
Initial Change:
The most noticeable color changes often occur in the first year or so of exposure, with the process becoming more gradual over time.
Not Just Darkening:
While lighter woods tend to darken, some darker woods might lighten over time due to the effects of UV exposure.
