When it comes to making a cutting board, one question that frequently arises is whether oak is a suitable wood to use. In this article, we will definitively answer this question and provide valuable insights into why oak may not always be the best choice. Instead, we will explore the benefits of using white oak for cutting boards.
Understanding Why Oak Is Discouraged
The primary reason why oak is often discouraged for cutting boards is due to its porous structure. Oak is a hardwood with open pores that resemble pipelines or straws, responsible for delivering nutrients throughout the tree. These pores are visible in the end grain of oak, and they are relatively large in size. When air is blown through a piece of solid oak, bubbles can be seen at the bottom, indicating the presence of these open pores.
The issue with the open pores in oak becomes apparent when considering that they have the potential to absorb undesirable moisture. Juices from meat or vegetables can easily seep into these pores and become trapped inside the wood. This trapped moisture creates an environment conducive to bacterial growth, rot, and other unpleasant outcomes. Consequently, many people caution against using oak in cutting boards.
Put to the Test: Does Oak Actually Absorb Moisture?
To ascertain whether oak truly absorbs moisture, an experiment was conducted using denatured alcohol, which is known for its quick absorption capabilities. The experiment revealed that oak absorbs the solution almost immediately and the moisture seeps through the top within a minute. Within two minutes, the oak becomes nearly saturated.
Considering this rapid absorption rate, it is understandable why using oak in cutting boards may not be ideal. However, it is essential to note that not all types of oak should be dismissed outright.
The Crucial Distinction: Red Oak vs. White Oak
While red oak is not suitable for cutting boards due to its porous structure, white oak possesses different properties that make it an excellent choice. White oak, in particular, is known for its resistance to rot and water. This is because the end grain of white oak contains tyloses, which are fiber-like resins that effectively clog up the pores, preventing excessive absorption.
In an experiment comparing the absorption rates of red oak and white oak, significant differences were noted. Even after sitting in water for five hours, the white oak only absorbed about an inch and a half, while the red oak absorbed nearly two and a half inches. Furthermore, when left overnight, the red oak exhibited noticeable warp in both the face grain and end grain, whereas the white oak remained flat, with minimal changes.
Considering these results, it is evident that white oak has distinct advantages over red oak when it comes to making cutting boards.
The Impact of Cutting Board Oil on Oak
To explore further, the experiment expanded to include cutting board oil. The question was whether treating the oak with oil would make a difference in absorption and warpage. After oiling the boards and allowing them to dry for 24 hours, they were placed back into the denatured alcohol solution.
The results showed that the absorption rates were relatively similar, with slightly less absorption in the oil-treated red oak. Surprisingly, the oil-treated white oak exhibited absorption rates nearly identical to dry white oak. However, the noticeable difference was in warpage. The oil-treated red oak did not warp significantly, unlike the non-treated red oak. The white oak maintained its stability regardless of oil treatment.
The Conclusion: Opt for White Oak
After carefully analyzing the results, it becomes clear that not all oaks are created equal, and red oak is not suitable for cutting boards. White oak, on the other hand, demonstrates rot resistance and minimal warpage, making it a superior choice. This raises the question of whether white oak absorbs more or less moisture compared to other traditional woods like maple, cherry, and walnut. Exploring this topic in-depth could be a future video.
In summary, when crafting a cutting board, it is advisable to use white oak over red oak. Its natural properties make it a reliable and durable material for this purpose. By selecting white oak, you can ensure a cutting board that resists moisture absorption, minimizes warpage, and maintains its integrity over time.
