This is a special tree.
It grows in Asia. People take juice from the trunk. This juice makes a hard, shiny coat. It helps make pens and bowls. Do you like shiny things?
The Chinese lacquer tree grows in Asia.
It can grow very tall. Its leaves have many small parts.
People tap the tree trunk for juice. They cut lines to collect the juice. This juice is a thick oil. It can cause a red rash on skin.
This oil makes a shiny coat. It is used on pens and bowls. The coat is very hard and stays waterproof. It looks very bright.
To make it dry, people use warm air. The air must be damp too. This helps the coat get hard.
People also use the fruit for wax. They dry and steam the fruit. This wax can make candles. It is a very useful tree.
The Chinese lacquer tree grows in parts of Asia.
It can grow up to 20 metres tall. Each leaf has many small parts called leaflets. Most leaves have 11 to 13 leaflets.
People use this tree to make lacquer. This is a hard, shiny coating. To get it, people tap the tree trunk. They cut 5 to 10 lines on a 10-year-old tree. Then, they collect the greyish yellow sap. This sap has a substance called urushiol. Urushiol is an oil that causes skin rashes.
Workers filter and heat the sap. They may also add colors. They use iron oxide to make black or red finishes. People paint the sap on items with a brush. To make it dry, they use a warm, damp room. This helps the urushiol polymerize. This means it changes into a hard surface. It stays waterproof and glossy. People use it on pens, bows, and bowls.
Some people use the leaves and seeds for medicine. The fruits can also make Japan wax. People steam and press the fruit to get it. This wax is used for candles.
The Chinese lacquer tree is a special kind of tree.
It is native to China and the Indian subcontinent. You can also find it in Japan and Korea. People call it the Japanese lacquer tree or the varnish tree. It can grow as tall as 20 metres. Each large leaf has many small leaflets on it. Most leaves have between 11 and 13 leaflets. Some leaves have as many as 19 leaflets. This tree is very important for making beautiful things.
People get a special liquid from the tree trunk. This liquid is called sap. To get it, workers cut 5 to 10 lines on the bark. They do this on a tree that is 10 years old. A greyish yellow sap then flows out. This sap contains urushiol. Urushiol is an oil that can cause skin rashes. It is the same oil found in poison ivy. You must be careful because even the vapors can cause a rash.
Making lacquer is a careful way of working. First, workers filter the sap. They might heat it or add colors to it. They use a brush to paint the sap onto an object. To make it dry, they use a warm and humid chamber. This is a room that stays damp and warm. The urushiol polymerizes in this room. This means it turns into a clear and hard surface. The finish is very glossy and waterproof.
There are many different colors of lacquer. Unpigmented lacquer looks dark brown. Most people use black or red finishes. They make red by using ferric oxide, which is rust. They make black using magnetite. This is also called ferrous-ferric oxide. People use this lacquer for many items. You might see it on musical instruments or fountain pens. It is also used on jewelry and archery bows. Some people even use it on tableware.
This tree can do even more than make lacquer. The leaves, seeds, and resin are used in Chinese medicine. They are used to treat internal parasites or to stop bleeding. The tree also has compounds like butein and sulfuretin. These are antioxidants. The fruits of the tree are used in another way too. People harvest, dry, steam, and press the fruits. This makes a substance called Japan wax. This wax is used to make candles or to varnish furniture.
The *Toxicodendron vernicifluum* is a remarkable Asian tree species.
It belongs to the genus *Toxicodendron*. Many people know it by common names like the Chinese lacquer tree or the Japanese lacquer tree. It is also called the varnish tree or poison sumac. This tree is native to China and the Indian subcontinent. However, it is also cultivated in Japan and Korea. It is highly valued because its sap can be turned into a very durable lacquer. This material is used to create beautiful lacquerware in China, Japan, and Korea.
The tree produces a special liquid called sap. This sap is harvested from the trunk of a 10-year-old tree. To collect it, workers cut 5 to 10 horizontal lines into the bark. A greyish yellow sap then exudes from these cuts. This sap contains a specific compound called urushiol. The name urushiol comes from the Japanese name for this tree, *urushi*. Urushiol is an allergenic irritant. It is the same oil found in poison ivy and poison oak. In its liquid state, urushiol can cause extreme skin rashes. Even breathing the vapours of the liquid can cause a reaction.
Making lacquer is a precise process that involves several steps. First, the harvested sap must be filtered. It may also undergo heat treatment or be mixed with colors. Once prepared, the sap is applied to a base material using a brush. To harden the coating, the object must be cured. This happens in a warm and humid chamber or closet. The curing process lasts between 12 and 24 hours. During this time, the urushiol undergoes polymerization. This means the liquid molecules link together to form a clear, hard, and waterproof surface. Once the lacquer has fully hardened, skin reactions are possible but less common.
Lacquerware is known for having an extremely durable and glossy finish. There are many different types of lacquer finishes. Unpigmented lacquer appears dark brown. However, the most common colors are black and red. To make black lacquer, workers use magnetite, which is also called ferrous-ferric oxide. To make red lacquer, they use ferric oxide, which is rust. The cinnabar-red color is especially highly regarded. People use this beautiful material for many objects. Common examples include tableware, musical instruments, and fountain pens. It is also used for jewelry and bows for archery.
Beyond its use in art, the tree has many other uses. The leaves, seeds, and resin are sometimes used in Chinese medicine. These parts can be used to treat internal parasites or to stop bleeding. The tree also contains specific compounds called butein and sulfuretin. These are antioxidants. These compounds have inhibitory effects on advanced glycation processes and aldose reductase. Additionally, the fruits of the tree provide another resource. They can be processed to create a waxy substance known as Japan wax. To make this, the fruits are harvested, dried, steamed, and pressed. The resulting wax hardens when it cools. This wax is used for making candles or varnishing furniture.
The *Toxicodendron vernicifluum* is a large tree that can grow up to 20 metres tall. Its leaves are quite large and complex. Each leaf contains between 7 and 19 leaflets. Most often, you will see between 11 and 13 leaflets on a single leaf. This tree has a deep connection to various cultural practices. For example, Buddhist monks who practiced the ceremony of Sokushinbutsu used the tree's sap. The tree's ability to produce both a hard lacquer and a versatile wax makes it a very important biological resource. It connects the worlds of art, medicine, and industry through its unique chemical properties.
