Oak wood, derived from oak trees belonging to the genus Quercus, primarily thrives in colder regions such as North America, Asia, Europe, and North Africa. Indonesia, with its tropical climate, may not be the natural habitat for oak trees, but its appeal knows no bounds in the local market.

One of the primary reasons for the widespread use of oak wood is its exceptional hardness. This quality is attributed to the relatively large wood pores that characterize oak, making it a favorite for various applications.

In Indonesia, where oak wood is considered a premium material, it is utilized for a range of purposes, despite its scarcity. From cabinets to indoor and outdoor furniture, window and door frames, and even wood flooring, oak wood has found a special place in the hearts of those seeking quality and longevity in their wood products.

The appeal of oak wood doesn't stop at its durability. Oak wood comes in two primary varieties: red oak and white oak, each with its own unique characteristics.

Types of Oak Wood

The hardness of oak wood depends on its type. There are two main types of oak wood: red oak and white oak, and they have distinct characteristics.

Red Oak

Known by its scientific name, Quercus rubra, red oak is primarily found in North America and Southeastern Canada. Its heartwood displays a rich reddish-brown hue, while the sapwood is nearly white. Red oak's straight, regular grain and relatively large pores set it apart. However, it has a lower resistance to termites compared to its counterpart, white oak.

The scientific name of red oak is Quercus rubra, and it is commonly found in North America and Southeastern Canada. These trees can reach heights of 25-35 meters with diameters of 1-2 meters.

The heartwood color is a light reddish-brown. The sapwood is nearly white, and the boundary with the heartwood is not very distinct. The wood has straight, regular grain and a somewhat coarse texture.

The wood pores are very large, so if you blow air into one side, it will come out the other. Red oak has a relatively low resistance to termites, especially when compared to white oak. It has low shrinkage, which increases its value and makes it easy to cut with machines. The finishing process and bonding with glue are straightforward. It reacts poorly to iron.

White Oak

White oak, scientifically known as Quercus alba, is commonly found in the Eastern United States. These trees can reach heights of 20-25 meters, which is shorter than red oak, and have diameters of up to 1.2 meters.

The heartwood color is a light brown with hints of green. The sapwood is light brown and doesn't have a distinct boundary with the heartwood. It's easy to distinguish between white oak and red oak based on their colors. White oak has straight grain with some rays and doesn't have a smooth texture. Visible growth rings can have 2-4 rows. White oak has excellent resistance to termites and fungi.

The best way to process white oak is through manual and machine sawing. It has low shrinkage after drying and remains stable. Changes in color can occur if it frequently comes into contact with rusty iron. It's easy to glue and can be coated with any finishing material. White oak is slightly more expensive than red oak.

The price difference reflects the differences in resistance between white and red oak. White oak is the more commonly found type in Indonesia, so be prepared to spend more if you want to use it.

Quercus alba, or white oak, is more prevalent in the Eastern United States. Its heartwood boasts a light brown color with hints of green, while the sapwood is light brown. White oak features straight grain with some rays and has excellent resistance to termites and fungi. This makes it a preferred choice for various applications.

Choosing the right finish for oak wood is essential to enhance its natural beauty and protect it from environmental factors. A transparent finish is often recommended to showcase the wood's natural color. Biovarnish products offer options for both transparent and natural finishes, allowing artisans to bring out the best in their oak wood creations.

With its sustainable and robust qualities, oak wood is proving to be an excellent choice for Indonesian consumers who seek long-lasting, aesthetically pleasing wood products. Despite the challenges of sourcing and processing oak wood, its appeal in the Indonesian market continues to grow. Craftsmen and homeowners alike are finding that the beauty and durability of oak wood are well worth the investment.

As Indonesia's furniture and construction industries continue to evolve, oak wood stands out as a testament to quality craftsmanship and sustainable choices in an ever-changing market.

Exploring the Appeal of Oak Wood and Its Various Applications in Indonesian Industry

Oak wood is produced from oak trees, which belong to the genus Quercus. These trees can only grow in cold regions like North America, Asia, Europe, and North Africa. There are hundreds of oak species that grow and are used for various purposes.

For those of us living in Indonesia, oak wood is considered expensive and hard to come by, even if you can find specific sizes. What makes oak wood so popular? The primary reason is that oak wood is known for its hardness.

The popularity of oak wood worldwide is due to the level of hardness it possesses. Oak trees can grow for hundreds of years, indicating an increase in wood quality over time.

The hardness and strength of oak wood are supported by its relatively large wood pores. Its unique texture makes it suitable for finishing processes. When still a tree, oak is often used as a shade plant due to its strong trunk and branches.

Oak wood's hardness level falls into class II, and it is resistant to fungal or termite attacks. A characteristic feature of oak wood is its large pores, but it is not considered a softwood.

The wide pores allow it to dry quickly when exposed to liquids or rainwater. Growing in cold climates provides oak wood with high resistance to cold weather and high humidity.

On the flip side, oak wood is susceptible to heat from the sun. Hot weather can cause the wood to warp due to significant shrinkage. Therefore, it's not ideal for outdoor furniture or items exposed to direct sunlight.

Processing oak wood can be challenging due to its tendency to crack. After the wood has dried, cutting it requires a sharp saw, or it may crack. If cracks occur during processing, glue can be used for repair. Avoid joining pieces with nails, as this is a primary cause of splitting. Use safer adhesives for furniture joints.

Pay attention to proper finishing and maintenance, as even though oak wood is resistant to termites and fungi, damage from these sources can still occur, especially in the high humidity of Indonesia. Wood preservation treatments for termites and fungi are needed before finishing. Ensure that the paint used contains good-quality additives.

Maintain the wood by regularly cleaning it from dust and polishing it. Oak wood is expensive, so it's advisable to perform regular maintenance.

Various Uses of Oak Wood in Indonesia

What are the functions and products that can be made from oak wood? Both white oak and red oak have different qualities and appearances, so it's essential to consider this when processing them into products for use. Here are various processed products that utilize white oak and red oak wood:

1. Cabinets: Cabinets, whether for the kitchen or clothing storage, are practical furniture for storing various items. White oak or red oak can be used as the cabinet material. The resulting colors are distinct from the native woods of Indonesia. The ease of cutting oak wood allows DIY enthusiasts to create their cabinets at home.

2. Indoor Furniture: You can use red oak or white oak for indoor furniture such as beds, TV stands, coffee tables, and living room chairs. All indoor furniture is not at risk of UV damage. High humidity can be managed with varnish or wood stain coatings, enhancing the luxurious look of oak wood. Transparent finishes expose the beauty of its colors and grain.

3. Outdoor Furniture: If you plan to create outdoor furniture like patio tables and chairs, opt for white oak. As mentioned earlier, white oak offers better resistance to termite and fungal attacks. However, it's essential to ensure that outdoor furniture doesn't make direct contact with the ground. For instance, use it for patio and terrace furniture. Furniture under a roof, like a balcony, can also use white oak.

4. Window and Door Frames: Oak wood can be used for window and door frames due to its durability. Frames made from oak wood are long-lasting and appealing, especially for minimalist house styles.

5. Wood Flooring: Oak wood, particularly white oak, is a popular choice for wood flooring. It's easy to finish and results in beautiful flooring.

Choosing the Right Finish

Understanding the characteristics, types, and functions of oak wood also involves the finishing process. Oak wood requires a coating that provides protection from the environment. One commonly recommended and chosen finish is the natural look. Oak wood doesn't have many imperfections, so you can achieve a transparent finish. Here are two finishing options you can achieve using Biovarnish products:

1. Transparent Finish

If you want to showcase the wood's natural color, go for a transparent finish. The first product applied is Biovarnish sanding sealer. After sanding the oak wood until it's smooth, apply the sanding sealer. Both sanding sealer and clear coat matte have the same application method. Mix the paint with water and apply it evenly with a nylon brush in the direction of the wood grain. The sanding sealer needs 60 minutes to dry, followed by sanding. Only after that, apply the clear coat with an overnight drying time.

2. Natural Finish

To enhance the wood's color while maintaining its natural appearance, use wood stain. Biovarnish offers three products for this: Biovarnish wood filler, Biovarnish wood stain, and Biovarnish clear coat. Wood filler should be applied using a palette knife or directly with a cloth after dilution. Its purpose is to fill all the wood pores to protect against humidity
