Does white oak have some black grain

[TonyL]

Now that I started engraving, turn a lot more wood that I have in the past.
I turned and CA finished a blank labeled white oak. This is the first time that I ever turned oak. I performed all of the steps that I usually do, and used the materials that I usually do. However, when I applied the first coat of thin CA, I noticed this black grain. stain, whatever it is.

Does white oak have black "grain"? I Googled around and I could not find that feature in an photos or descriptions.

I did have red oak kitchen cabinets when I lived in NY, and I remember some darker, ashy, grain. But this blank had no hue.

Thanks!

Tony, the short answer is no. The long answer is there are at least 26 species of oak and it gets very tough to tell what is what in a small sample size. This is white oak.

It could be a spalt line from a fungus that just started when the wood was processed.

Could also be mineral staining.

Tony, I believe that the "tannin acid" found in species like white oak reacted to the CA finish that you applied and thereby released the "black" streaking of the wood.

Thank you all. I will sand and use pens plus and see what happens.
