Medullary Rays Are Naturally Occurring in Oak Wood

Medullary Rays Are Naturally Occurring in Oak Wood

WHAT ARE MEDULLARY RAYS
Medullary rays are cellular structures found in the trunks of trees. In a cross section of a tree trunk, they are visible to the naked eye and appear as radiating lines from the center of the log, perpendicular to the growth rings. These medullary or pith rays are essential and serve as a link between pith (center) and cortex (periphery) of the live tree. They perform various functions like food storage and transport of food and water.

WHAT DO MEDULLARY RAYS LOOK LIKE AND WHEN DO THEY APPEAR
In a finished piece of furniture or countertop, medullary rays may appear as rays, silking, and pith flecks. Depending on where the board is cut on a ray, the appearance can be squiggly lines, straight lines, glowing lines, brush marks or flecks. While these rays functionally exist in all trees, they are especially noticeable in lumber from oak trees, like Appalachian Red Oak and White Oak found in some of our BB Co. products.

When boards are cut from an oak log, they are usually rip cut along the length (axis) of the log. This can be done in three ways: plain-sawing (most common), quarter-sawing (less common), or rift-sawing (rare). Most of the lumber we use is from plain-sawn boards and will result in wood grain in an oak countertop that will have a varietal appearance. The “normal” grain appearance may show up as “cathedral grain pattern” with high peaks in the grain, or a “long straight grain pattern.” However, in plain-sawn oak there will always exist some quarter-sawn lumber, too. (And even some rare rift-sawn grain may be present in plain-sawn boards.)

In quarter-sawn material, where the wood is cut into boards with the growth rings roughly perpendicular to the face of the board, the medullary rays are more abundant and conspicuous, often producing beautiful markings such as silver grain, medullary spots and pith flecks.

OTHER WOOD ITEMS COMMONLY FOUND WITH MEDULLARY RAYS
In some fine wood instruments, like high-end string instruments, the neck and fretboards may be made from quarter-sawn wood to help them remain stable throughout the life of the instrument and to keep the instrument in tune. In acoustic guitars, quarter-sawn wood is also often used for the sides which are steam-bent to produce the curves. Quarter-sawn is used in part for structural stability, but also for the appealing aesthetics of its wood pattern. Additionally, high-end cabinets may be made from quarter-sawn wood which puts the medullary rays on the face grain of the cabinets. It is also especially desirable for furniture and decorative paneling.

CONSUMER PREFERENCES
Medullary rays are going to exist in oak furniture. Unfortunately, we cannot predict how many, what kind, and how conspicuous they will be. Therefore, a consumer must make a thoughtful decision before they order an oak countertop, kitchen island top or table. Given the size of most countertops, medullary rays are very likely to appear in an oak top. For a smaller table, the likelihood of medullary rays probably goes down, but again, it really depends on the cut rails. If a piece of lumber has many medullary rays and is cut into rails for a table top, they are very likely to appear all in one table.

  • LOVE IT – Some people consider this quarter-sawn wood with medullary rays “prized” and they pay more for it! If that is you, then consider a quarter-sawn plank-style top because when sawn this way the result is boards with the annual rings mostly perpendicular to the faces. The likelihood of medullary rays increases and, when present, are going to be more prominent than in a plain-sawn board constructed as an edge grain top. These medullary rays often produce beautiful markings. Compared to an edge grain oak top, quarter-sawn boards often have greater stability of form and size, with less cupping, shrinkage across the width, and shakes and splitting.
  • HATE IT – We have had some customers think medullary rays look like defects in the wood and they find the overall aesthetic unappealing. While these customers are a small minority, we take their opinions seriously. If you might be that person, we recommend you consider a species other than oak. For example, our best selling Maple Country Work Table is the sister to our popular Oak Country Work Table and a good option to consider. And for kitchen island tops we have 13 other wood species available from which to choose!

Just remember, medullary rays are naturally occurring in oak wood, not considered a defect, and the amount and type cannot be predicted, nor guaranteed. It is part of what makes wood so special. Every piece is truly different, and therefore, every countertop or piece of furniture is beautifully unique!

Celebrating 4 Years of BB Co. Brand Custom Countertops

Celebrating 4 Years of BB Co. Brand Custom Countertops

This month, we at Butcher Block Co. are celebrating our four year anniversary of our BB Co. brand counter and island tops! We’ve had so much fun seeing these beautiful tops in your homes and restaurants, and we’re excited to share some of our favorite recent projects. We want you to join in the celebration, so check out our BB Co. brand tops here. Share your photos and you could even be featured in a future blog post!

First up, our customer Tyra put together one of the most creative uses of our butcher block we’ve ever seen. Tyra ordered BB Co. Hickory Plank for her beautiful island top, and individual backsplash pieces to build this amazing range hood. Her contractor did a remarkable job, and this is one of our favorite kitchens to date. Hickory has grown rapidly in popularity over the last couple years, and it is not hard to see why when you look at Tyra’s phenomenal kitchen!

Our happy customer, David, ordered a Red Oak Plank top, and customized it to his liking. He ordered the top unfinished, then stained it and applied six coats of polyurethane for this spectacular island top. Great job, David!

Finally, we have this absolute stunner of a tabletop from a new Italian restaurant in San Diego. GTC Design (also in San Diego), ordered a Knotty Alder Plank top at 115”L X 66”W (it’s huge!) for their client, Cardellino. Large enough to seat 18 people, this gorgeous table is perfect for big groups, and graces the private dining room at Cardellino. It was paired with an old industrial workbench base, which gives it the perfect touch of rustic charm. Wouldn’t it be amazing to have something like this in your home?!

We hope you enjoyed our celebration! And, remember – if you are looking to put in a new counter/island/table top, we’re always her to help make your butcher block dreams come true!
