ElmWoodUA Thermowood End Grain Cutting Board

Thermowood is wood that has been heat-treated in a controlled environment to remove moisture and resin. This process makes the board significantly more resistant to warping, shrinking, and decay compared to untreated wood, ensuring it stays stable even in humid kitchen environments.

In an end-grain board, the wood fibers run vertically rather than horizontally. When you cut, your knife blade slips between these fibers instead of slicing through them, which keeps your blade sharper for longer and prevents deep scarring on the board's surface.

No, this board is not dishwasher safe. High heat and excessive water exposure in a dishwasher will cause the wood to warp or crack; always hand wash it with mild soap and dry it immediately.

The black color is achieved through the thermowood treatment process, meaning it is integrated into the wood itself rather than being a surface stain or paint. While the finish is durable, regular oiling will help maintain the deep, rich color and protect the wood fibers.

To keep the wood hydrated and prevent cracking, apply a food-safe mineral oil or beeswax conditioner every few weeks, or whenever the wood starts to look dry. Avoid soaking the board in water and never leave it submerged in the sink.

The non-slip feet are integrated into the design to provide essential stability while you chop. They are not intended to be removed, as they also help elevate the board slightly to allow for airflow underneath, which prevents moisture buildup.
