What type of wood is this - experiences

Hello,

I have some old stair steps from an older house here. At first, I thought it was beech wood, but after sanding, I am now not sure what it actually is. If it weren't for the grain, I would wonder if it is even wood at all. When sawing, the sawdust is also more like dust. Background: I want to make a cutting board for our new sink out of it, so it should not be wood that possibly contains toxins. The board will also be planed about 1cm thick on both sides. Can someone with experience tell me something about the wood?

Thanks for your help

Doesn't seem to be a native wood. At first glance, I would say mahogany, doussie, or something of that kind.

Then it would be pretty noble…?!? If it helps, I just calculated that 1m3 weighs about 590kg. This piece about 47x27x4.5 cm weighs 3.4kg. If it were actually mahogany, would it be suitable as a cutting board?

First of all, mahogany would be a completely common stair covering in old houses.

And yes, of course you can make a cutting board out of it. Why shouldn't a hardwood be suitable for that? You can also buy them in the store made of mahogany.

The harder the wood, the shorter-fibered the "shavings". Obviously, it is solid wood, what toxins should it contain? - Protective gas from container transport from overseas? After planing off 1 cm, any penetration depth of chemical impregnations should be removed. If it doesn't wobble, I wouldn't plane anything off here for a cutting board.

Toxins rather not, but tropical woods have many wood constituents that can react with food. With dry foods, such as bread or carrots, not so serious, with acidic, moist or fatty foods, interactions can occur.
