Solid bog oak floorboards

The most unique article we have (and probably no other company in the world does) is the solid bog oak floorboards (also called rivers oak). We possess a radiocarbon analysis certificate for this wood, which is 1400 years old!


We offer two types of bog oak:

1) from old river layers – the wood color for this type ranges from graphite to deep black (similar to African ebony).

2) from sand layers – the wood color for this type ranges from gray to a full spectrum of brown, up to an intensely burnt coffee color.


You can find all color types and production photos in my Dropbox gallery (Currently available in shades of bronze)  :

Bog oak, also known as black oak, fossil oak, diamond oak or Polish ebony, is one of the rarest and most exclusive raw materials used for finishing interiors.

Bog oak is not the name of a tree species, but of oak trunks submerged in water. Oak trees which have found themselves under water, as a result of either natural events or human activity, undergo a wondrous transformation. The centuries-long process of reactions taking place between the tanning agents – oak wood compounds and salts contained in water – changes both the color and the properties of wood.

As a result of the above reactions, the wood becomes permanently dyed – to the color of intensively burnt coffee through graphite up to deep black.

The chemical and physical changes that take place over the centuries make the wood even harder, and due to increased density it becomes one of the most durable, and at the same time most difficult to process, species of wood known to the man.

We should add that in the past the use of bog oak was reserved only to kings and the most affluent gentry in Europe. It was used for manufacturing handmade period furniture, jewelry, and for making the most durable floors.

The hundreds of years needed for creating bog oak, together with its extremely challenging processing, required to reveal is full beauty, make it the most exclusive article in our offer.

Specially for our most demanding customers, we offer floorboards made of this noble wood.
