Is it a species of pine in and of itself? Is it just what the name suggests, the heart of any pine tree? What ,exactly is is? The heartpine that I have aquired recently is some absolutely beautifull wood with a deep reddish color varying all the way to a golden yellow with growth rings so numerous that can barely be discerned. Some of it has, as best I can count, 29 rings per inch. It is so dense and heavy that it seems to be like no other pine I have ever felt, except maybe SYP, which it looks nothing like. I really am at a loss as to what to make with it but I want to use it for something, it is really nice looking wood. It is very resinous though and gums up sandpaper in no time. I know of an almost unlimited supply in some very large dimensions, not that I want build a house out of it or anything but there is a lot there.
So, what exactly is it??? I saw nate22’s post earlier about pine and it got me to thinkin’.
Thanks for any help

I think that there is a standard for what is considered heart pine by the growth rings, but i could be thinking about “old growth”. Ill be watching this thread … nice topic Bill. And welcome to the gang.

Here is some info on the subject. It seems there is no easy answer to your question.

heart pine is actually southern yellow pine with the sap wood removed during the milling process, heart pine refers to the heart wood of the tree which is much more dense due to the high resin and pitch content hope this helps

Charlie, thanks so much for that link. Very informative. The way that the longleaf heart is described certainly sounds just like what I have. It feels as dense as hornbeam. The information about boatbuilding uses certainlt is encouraging to me as well. They say it was used alot for masts, I wonder how it would work serving as other structural members of a boat. HUMMM? :)

As said, heart pine is the dense, pitch soaked, heartwood of southern yellow pine trees. It can be loblolly, shortleaf, slash, or longleaf pine. The most heaviest and dense and slow growing old heart pine lumber is usually longleaf. The grand old stands of longleaf pine are now mostly gone. There is little longleaf pine lumber being produced anymore. Most of what you see is reclaimed from old factories and buildings.
