I have lots of pieces of pine furniture which have different colours depending on how old they are. So, I just wondered why that is. I guess it has something to do with structures and chemical compounds that were already in the wood when it was still alive, so I hope this is not off-topic here.
What processes take place in dead wood when it ages?
What determines the colour it will have? For example, pine and spruce wood looks very similar when freshly cut, but will develop very distinct colours afterwards.
Is there also wood that does not become darker?
Is it something to do with the processing of wood, or will that happen to any stick you leave lying around in your room (so it doesn't rot)?
