White oak color12/7
I have a piece of white oak that has stripes running across the width of the board. They are not consistent with stick spacing as you can see and the stripe goes clear through the board. The customer says that when coated with poly or stain these stripes pop out like stain. I've never seen this before. Thoughts?
Looks like burnish marks to me, from the surfacing machinery. Who did the surfacing?
I did not show the photo of the SLR1E but the markings go all the way through. The customer also claims to have seen this in other lumber from a different supplier. I believe it's something naturally in the wood but looking for a confirmation.
1. Who surfaced the lumber? I can see mill marks on the surface.
2. Has it been properly sanded? 120 grit minimum.
3. Is there some one with lots of real shop/lumber experience looking at these boards?
4. Sticker stain (look it up) can go all the way thru a board, but it is rare to see stickers close to each other, so was this lumber from a reputable vendor that knows how to dry lumber?
5. SLR1E has nothing to do with the complaint or conversation - is it a red herring?
You need to supply much more info and do a little more research before anyone on an internet forum can offer much help. Without lots of context, your questions will just flop there.
I'm curious how you know it goes all the way through without sanding or surfacing it. Run a piece through a wide belt sander and then check it. Millmarks will pop out like crazy when stained or just finished. Is your customer prepping the boards before finish??
Ok guys here goes.
What we have here is something that i see only once every three or four years. That is, it is very rare. Most people have never seen it, or if they saw it, did not know what it was so forgot about it.
This is unique to white oak. It occurs in the tree and not after harvesting, sawing or drying. It shows up most clearly after drying and planing.
So, what is it caused by? It is caused by a fungus, somewhat like blue stain, but in this case is dark. Somewhere in my notes I do have a name for this fungus, but it did not pop up right away when I looked...sorry.
Jerry - I meant you no disrespect in my earlier post. I just was unsure of your level of experience. Turns out you know what you are looking at.
But....it looks like you may want to buy back any lumber with this 'defect' and then sell it at a premium for its rare and unique appearance. Lemons> lemonade!
Ha ha. We told our customer he should be paying a premium for our tiger striped white oak.
