All natural and food safe. What’s especially cool about these boards, is the all-natural process that transforms their shade to black from within — there’s no dye or pigment applied. Instead, ferrous acetate is applied to the wood’s surface and reacts with tannic acid, a natural component in teak.

The reaction causes the deep dark hue to appear from compounds inherent in the wood. Pretty awesome, not to mention environmentally safe. Currently the lineup features three types of boards, a butcher’s block, a bent spatula and a step stool, with more items, like a mortar and pestle, on the way.
