Black mold or bluing?

[Matti_75]

and what do you mean happens when it's dry?

Read up on mold and you'll understand why you shouldn't enclose it!! I'm not just guessing when I answer, I'm basing it on facts

@Staffan2000 do you think I should comment?

I think it looks like bluing. Because it's probably pine. It occurs in pine when they've been lying too close to each other during the drying process. That's why you always use spacers of spruce when sawing pine. Regardless of what it is, I would never build it in, it's just unnecessary to have to think about it later. Good luck.

Yes. For bövölen. Don't forget to include asbestos, Japanese knotweed, old fluorescent lamps, masks, and farmers.

If the OP is worried, just spray some borax and it's guaranteed to be calm.

If TS is worried, just spray on some borax and it's guaranteed to be fine.

Out of the frying pan, into the fire.

"Borax, sodium tetraborate, is reproductive toxic and classified as a phase-out substance (it has such serious properties that it should not be used)"

How strange, when I started with carpentry, blue pine for furniture was 1000 SEK more expensive per cubic meter than "regular pine"

"Borax, disodium tetraborate, is a reproductive toxin and classified as a phase-out substance (it has such serious characteristics that it should not be used)"

Yep, the mold-inhibiting component in lots of building materials, e.g., eco-fiber. But many use boracell to impregnate raw wood in attics and elsewhere. Tragic but true.

No, I think you should share your facts instead of sitting and claiming something that's not true. It's hardly the case that such timber starts a process that continues to mold inside. It dries out and dies, and even if there are super sensitive people who can react to anything, it's still at levels where the air concentrations are a thousand times higher elsewhere. So in the end, it's just a bit of discolored timber that doesn't affect anything. Or what do you think will happen?
