Roasted Ash is White Ash (Fraxinus americana) that has been subjected to a high-heat, low-oxygen thermal modification process. This process dramatically changes the wood's properties, darkening its color to warm chocolate browns.

Thermal modification (roasting) provides several key benefits: it reduces moisture absorption by 50% or more, significantly improves dimensional stability and resistance to warping, darkens the color to brown tones, and can improve rot resistance. The process uses only heat and steam, no chemicals, making it an environmentally friendly treatment.

Roasted Ash has a warm, chocolate-brown to dark caramel color consistently throughout the wood.

Yes. Roasted Ash's moisture resistance make it more suitable for outdoor and high-humidity than regular Ash. It is still recommended to apply an exterior-grade oil or finish for protection in fully exposed outdoor installations.

Roasted Ash and regular White Ash differ significantly in their properties. Roasted Ash absorbs 50–80% less moisture, has improved dimensional stability, a darker brown color, and improved rot resistance. It is more stable in environments with seasonal humidity changes. Regular Ash is slightly stronger and harder, as roasting can slightly reduce strength.

Roasted Ash is used for flooring, furniture, cabinetry, exterior cladding, decking, bathroom furniture, saunas, and other applications.

Yes. Thermal modification is a process using only heat and steam, no chemicals or preservatives. Roasted Ash is considered food-safe for cutting boards and kitchen items when finished with food-safe oils or wax.

Yes. The roasting process reduces Ash's hardness slightly, typically by 10–20% compared to regular White Ash (Janka ~1,320 lbf).

Penetrating oil finishes, hardwax oils, and exterior-grade oils work best on Roasted Ash.
