This substance is made through a process called destructive distillation. This is a way of breaking down wood using heat. First, workers put pine wood into a closed container. This container has no air inside. Then, they apply high heat and pressure to the wood. The wood breaks down into two main things. One part is charcoal. The other part is the pine tar. The exact mix of the tar can change. It depends on the type of wood used. It also depends on how hot the fire is.

People have been making pine tar for thousands of years. In Sweden, scientists found special pits used to make it. One of these pits is very old. It dates back to between 540 and 380 BCE. This might be the oldest tar site in the world! Later, a Roman writer named Pliny the Elder wrote about it. He lived from 23 to 79 CE. He said people in Europe used it to coat ships. In the 1600s, many countries needed a lot of tar. They used it to build big fleets of ships. In Finland, making tar became a huge business. By the late 1600s, it was a very valuable export for Sweden.

Tar has many important jobs in the world. Sailors used it to keep wooden boats waterproof. They would mix it with oil to seal the wood. This helped the boats stay strong in the ocean. They also used it on hemp ropes so they would not rot. Sailors who worked with tar were even called "tars." In the 1800s, Swedish tar was very famous. It was often called "Stockholm tar." People thought it was the best quality tar available.

It helps them get a better grip on the handle. However, there are strict rules in Major League Baseball. Players can only put it on the bottom 18 inches of the bat.

Scientists have studied what is actually inside pine tar. They found 32 different compounds in tar from the Pinus nigra tree. These parts make up 95.5% of the whole thing. One big part is called Methyl dehydroabietate. It makes up 22.44% of the mix. Another part is Dehydroabietic acid, which is 14.59%. These parts help the tar kill germs. This is why it works so well as a preservative. It is amazing how a simple tree can create something so useful.
