Ancient Kauri It's called ancient kauri, and it's up to 50,000 years old. Yes, 50,000! The oldest workable wood in the world, ancient kauri shows just the earliest signs of petrification. Called "whitebait," this phenomenon creates small veins of mineral deposits that give the wood a one-of-a-kind luminescence. 50,000 years ago, in what is now Northern New Zealand, a major natural event felled huge forests of kauri trees that had been growing for some 2,000 years. This event also created bogs in the area that protected these giants from the elements. Today these trees are typically found under farmland from which they are carefully excavated before the ground is returned to its previous contours. Just for some perspective, here are a few things that happened on Earth less than 50,000 years ago… 16,000 years ago the depressions that would become the Great Lakes were fully formed. The last Ice Age ended approximately 5,000 years ago. Homo Sapiens reached the area from which these trees were recovered only around 40,000 years ago. Bog Oak No, this wood isn't stained black. 5,000 years in a peat bog in the Ukraine have naturally turned these huge, ancient oak trees black all the way through. At the end of the last ice age rising water levels caused huge oak forests throughout Europe to die standing and fall into the muck. For the last 3,500 - 5,000 years these trees have been preserved in anaerobic conditions underneath peat bogs. The ages have turned bog oak a deep black with dark brown grain. This is the result of a chemical reaction that occurred between the tannins in the oak and soluble irons present in the bog soil.
