By carbonizing / fuming treatments we have the benefit that the color is not a stain sitting on top, but our heat treatment changes the structure of the wood, making it dark brown (carbonized) or black (fumed) going through the entire face layer. In case you scratch your floor, no lighter color will come through.
Although these technical differences may not be visible to the naked eye upon making your decision to purchase, they may have huge impact later on down the road. Wood is a natural product and is always fighting to go back to its circular original form. It is important to know and understand the characteristics of wood and use the best methods and technologies available on the market to ensure you have a higher quality product.
