Why is white oak water-resistant?

White oak contains tyloses — balloon-like cell growths that block water penetration. This is why it has been used for centuries in boat building and barrel making.

Is ash supply declining?

Yes, the emerald ash borer has devastated North American ash populations. While still available, long-term supply is uncertain in many regions.

Which is better for a dining table?

Both are excellent. White oak's warm tones and water resistance make it ideal for dining, while ash offers a lighter, more casual look.

Can ash be used outdoors?

Untreated ash has poor outdoor durability. White oak is the much better choice for outdoor furniture and projects.
