Some random wood related stuff from today. I've replaced our old french doors and needed to make new trim, the new doors are slightly smaller than the old so I dug out some oak from the barn attic. The first pic is of freshly finished red oak and 30+ year old. Same finish (Waterlox). The trees were within 100' of each other. The difference is just time, sun and oxidation.
The second pic was from doing some cleanup of the old collapsed house on the neighbor's property. The previous owner was a packrat. I haven't seen any in a few decades but celotex, a fiberboardish wood fiber sheet with an asphalt coating was the go to sheathing from my youth through about the 90's. Around 2000 is when the IRC and the ever expanding wall chapter of the code kicked in.
Edit; Looking at the oak pic, the wood is flatsawn, roughly tangent to the rings. The "chicken scratches" you can see in both sticks is the end on view of medullary rays, the radial, in/out transport cells of a tree. They are obvious in the oaks, white oak having the largest.

After mentioning the rays yesterday, the middle board in this pic popped as I walked by today. That is quartersawn, like a spoke on a wheel, a straight radius line from heart to bark. So in that board the saw passed in line with the medullary rays and shows them off. They are only a cell or two thick, multiple cells tall and quite a few long. They also tend to flash as the angle of light and sight changes, the tiger eye effect, "chatoyance".
