Have you ever wondered how wood fuming can transform the color of wood all the way throughout? Let's dive into the fascinating process that involves using ammonia gas to achieve this remarkable effect.
How does fuming work?
When wood is exposed to ammonia gas, a chemical reaction occurs between the gas and the tannins present in the wood. This reaction leads to a darkening of the wood, changing its color significantly.
Why does the color change penetrate deep into the wood?
Wood is a porous material, allowing the gas to penetrate deep into the fibers of the wood. Given enough time, the ammonia gas can reach the center of the wood, resulting in a color change that extends throughout the entire piece.
Is fuming a surface treatment?
No, fuming is not a surface stain. Instead, it alters the wood fibers all the way through. This means that you can sand and refinish the wood multiple times without affecting the color. There is no need for restaining, as the color change is permanent and consistent throughout the wood.
Next time you come across a piece of wood with a rich, dark color, remember that it may have undergone the fascinating process of fuming with ammonia gas. The depth and permanence of the color change make it a popular choice for achieving unique and long-lasting wood finishes.
