Ever brought home a gorgeous Black Walnut slab, only to watch it warp on you a few months later?
A slab can feel bone-dry on the outside while still holding 20% moisture deep inside. Wood at that level will warp, crack, or push joints apart once it settles into your home.
That's why we kiln-dry our local Ohio hardwoods below 8% before they ever leave the shop. It's also why sealing the underside of your slab matters just as much as finishing the top. Skip either step and you'll feel it every time you look at the piece.
