the REST of the pictures on this page will give you a better overall feel for this wood
persimmon / Diospyros spp. of the family Ebenaceae
3" x 3" flat cut, 3" x 3" quartersawn, 1" x 1" end grain, and a 1/4" x 1/4" end grain closeup.
Semi ring porous with sparse pores starting out medium sized and reducing to small by the end of the latewood, and with vasicentric parenchyma throughout. Occasional radial pore multiples. Reticulate parenchyma is present but usually hard to see even at 10X. Likewise seemingly marginal parenchyma. Rays are thin but visible at 10X and ring boundaries are distinct.
This wood has a VERY small heart area that is deep brown or black, which makes it clear why this is in the ebony family. The wood is generally only available as sapwood, which is creamy white, sometimes mottled with gray, and very hard and tough and resistant to wear but with a large movement in service. Used for golf club heads because of extremely high shock resistance.
If not cut at the right time of year and dried properly, the wood will season to an ugly gray pretty much throughout, not just on the surface, and it is very prone to warping if not dried properly. One of my own sample chunks (see below) started out as an unseasoned log portion that was off-white but after it had been seasoned for a year or two, it was gray inside and out when I cut it up. I had heard anecdotally that the gray was only "skin deep" but that is clearly not the case.
The graying process does stop after a while. One of the little chunks referenced in the paragraph directly above sat around for several years and was still exactly the same color as it is shown on this page. I assume then that the graying is part of the seasoning and stops once the wood is seasoned.
