Magnifier for wood ID
Actually, you just need a hand lens and not a microscope. This is my favorite, good lens, built-in LED lights, and inexpensive! (I bought several of these for the shop - handy in the machine shop, around wood, for splinters...):

I do use a microscope just because I have one on my desk. Note that most microscopes do not have a low enough power to be useful; I couldn't use my laboratory microscopes unless I wanted to look at the cells! The one I use is a low-power stereo microscope, 15x at the lowest power.
Box Elder for sure. Have plenty of it myself.
Is this related to Manitoba Maple? Because the red stain looks almost identical.

My first pieces were cut with it sopping wet. The wood cut like butter, very nice consistent grain, but white as can be and boring. I stained the first one red in frustration.
The second large bowl was coated in anchor seal and stored for drying. After a month the red patterns formed and it may look really nice.
I assume its a fungus (or reaction to) that specific to the wood species.
But the colors have not penetrated very deep so far.

Manitoba Maple is just another common name--hence the reason for scientific names. Same as Box Elder for sure which is a true Maple to confuse things even more.

The page mentions the fungus as well.
I like the looks of it but it is really soft compared to other maples that grow here.
Box Elder is considered by many to be a "trash tree" in that the branches have a hollow pith, are weak, and break easily and the seeds sprout easily EVERYWHERE! It is terribly soft and doesn't seem to store well in my experience. I have had some get dry rot.
Gentlemen, Thanks again for all the information! I really do appreciate it. I have a jewelers loupe, and that is how I looked at the end grain. I also have access to microscopes, but after looking with the loupe, it was obvious it was not chestnut. The only issue I have now is my wife, who loves the bowl, will still not let me bring it in the house! I put 3 coats of Tung Oil on it, and my better half is VERY sensitive to odors. The bowl is still sitting in my work shop where it will stay until the odor dies down... If anyone knows of a way to speed up this process, please tell me. This piece was my first try at turning, and the piece of wood I chose to use was one of the final pieces I salvaged. It was a piece of scrap to learn on... It will be interesting to see if the wood I thought would be really nice is any better. Thanks again!
What “Tung Oil” did you use Dan, or was it “Tung Oil Finish”, also you say 3 coats, in what time did you apply that, I mean time between coats, your shop is held at what temperature ??

Leo, I used Behr "Tung Oil Finish". The 3 coats were applied as per the instructions, at one hour intervals. My shop temperature? My home "shop" where I do the turning is my basement that is not temperature controlled. The temps in the basement since the finish was applied range from 55-65*F. I should also mention the Tung oil finish I used has been in my shop for over 10 years... When I opened it, it looked and smelled just as I remembered it. It does not go bad does it? Thanks! Danny
I was afraid off that, about the so called Tung Oil Finish, this stuff has no Tung Oil in it, to get around that they Lying , they add the word “finish" behind the Tung Oil, and if you ask the makers, they will tell you that this stuff will make it LOOK LIKE a Tung Oil finish.

Oil does float on water and so you can keep the bottle full very easily, the bottle I use is a re-closable Beer bottle, and I have done this for at least 20 years and have never had a problem with that.
Tung oil does have to polymerize before you can add another coat, and that does take a while, if you add another coat before that, the first coat will not get the needed air contact and will then not fully harden up for a very long time if ever.
For that reason I buy what is called Polymerized Tung Oil, it has been heated at quite a high temperature without any air, by doing this the Tung Oil gets too thick to use easily, so a volatile thinner is added which will evaporate quite quickly and the Polymerized Tung Oil will then harden in about 8 Hrs if the temperature and humidity is right, too cold and it will not happen, but temps above 60F will work fine, below 40F it doesn’t, I normally leave it just overnight before adding the next coat.
I get my Polymerized Tung Oil from Lee Valley.
Behrs MSDS info
Just to add here, Minwax does the same thing, and sells Tung Oil Finish, and things like Teak Oil finish, so you better find out what you really buy, pull the MSDS sheets up and read all of it, or never buy from these Companies.

Lying to sell something
Shame on them. I understand the "Danish" oil label is also a bit misleading.

Even if it is real honey I would hesitate to buy it from the grocery store. Much of it comes from China and much has be found to contain high levels of pesticides. I remember when inspectors rejected one contaminated shipload on the east coast but the importers somehow got it in through New Orleans. The importers do tricks to get around the bad reputation of Chinese honey such as ship to Argentina and then import it into the US as Argentine honey.
Since honey can be fingerprinted by analyzing the pollen it contains, the Chinese have also heated and filtered out all the pollen. Unfortunately, heating also destroys the beneficial enzymes and taste.
I saw another misleading label once. Since Sourwood honey is desired by some, one company called itself the Sourwood Honey company and labeled it's non-sourwood honey as Sourwood Honey. Good grief.
BTW, for the best honey buy local. Look for "raw, unheated, unprocessed" honey.
