What Is Seasoning of Timber?
The wood spice process is the process by which the moisture in the wood is reduced to the required level. By reducing the moisture content, strength, elasticity, and durability properties are developed. A well-seasoned wood contains 15% moisture content.
It is a process by which the amount of moisture in a freshly cut tree is reduced to a suitable level. Doing this increases the durability of the wood. The different methods of spice used can be classified into:
Type of Seasoning of Timber
- Natural seasoning.
- Artificial seasoning.
1. Natural Seasoning
It can be air seasoning or water seasoning.
1.1. Air Seasoning
Air seasoning is done in the shed with a platform. As shown below fig, wooden piles are stacked on platforms approximately 300 mm high.
Care is taken to see that there is proper air circulation around each wooden hair. Over a period, the moisture content decreases in a natural process. A well-seasoned wood contains only 15% moisture. It is slow but has a good seasoning process.
Water is sprayed on the banks of rivers. The thick end of the wood is placed, pointing upwards. After a period of 2 to 4 weeks, the wood is taken out. During this period, the sap contained in the wood is largely washed away. The wood is then stalked in a shed with free air circulation.
1.2. Water Seasoning of Timber
Water seasoning is the process in which timber is immersed in water flow which helps to remove the sap present in the timber. It will take 2 to 4 weeks of time and after that, the timber is allowed to dry. Well-seasoning timber is ready to use.

2. Artificial Seasoning
In this method, the wood is kept in a chamber with regulated heat, Controlled humidity, and proper air circulation. Seasoning can only be completed in 4 to 5 days.
There Are Different Ways of Seasoning:
- Boiling Seasoning
- Kiln Masala Seasoning
- Chemical Seasoning
- Electrical Seasoning
2.1. Boiling Seasoning
In this method, the wood is immersed in water, and then the water is boiled for 3 to 4 hours. It is then slowly dried. Hot steam can be circulated on wood instead of boiling water. process of The spice is sharp but expensive.
2.2. Kiln Masala Seasoning
The kiln is an airtight chamber. The seamed timber is placed inside it. Again fully saturated air with a temperature of 35 ° C to 38 ° C is forced into the kiln. Heat slowly
The kiln used may be stationary or progressive. Carts moving from one end of the wood kiln to the other end in the progressive kiln are gradually eliminated.
Hot air is supplied from the discharging end so that the temperature rise is gradual from the charging end to the discharging end. This method is extensively used to make spices.
2.3. Chemical Seasoning
In this method, the wood is immersed in a suitable salt solution. The wood is then dried in the kiln. Initial treatment by chemical seasoning ensures uniform spicing of the outer and inner parts of the wood.
2.4. Electrical Seasoning
In this method, a high-frequency alternating current is passed through the wood. The resistance to electric current is low when the moisture content in the wood is high.
Reduced moisture content reduces resistance. A measure of resistance may be used to prevent spice at the appropriate level. However, it is expensive to process. This technique has not been attempted in some plywood industries but on large-scale wood spices.

Reason for Seasoning of Timber
Wood seasoning is applied to meet some specific requirements. There is a reason for wood seasonings to follow.
- To change and improve the qualities of wood.
- To make a correct percentage of wood shrinkage.
- To ensure the use of forests.
- To reduce the adverse behavior of wood.
Improved Ability by Seasoning of Timber
By seasoning, some commonly known properties are improved which are outlined below:
- Strength
- Hardness
- Durability
- Weight
- Painting and finishing
- Gluing
- Resistance to insect attack
- Electrical Resistance

Seasoning of Timber
Seasoning is the process of drying timber to remove the bound moisture contained in the walls of the wood cells to produce seasoned timber. Seasoning can be achieved in a number of ways, but the aim is to remove water at a uniform rate through the piece to prevent damage to the wood during drying (seasoning degradation).
Artificial Seasoning of Timber
Artificial seasoning is the process by which lumber is dried using man-made devices such as a kiln. Regular wood seasoning is done by air drying in conditions below 18 percent moisture. There are multiple advantages to having wood artificially seasoned that relate to the quality, strength, and cost of the wood.
Wood Seasoning
Seasoning wood is the process of correctly drying timber in order to remove moisture in the cells of the wood walls. It is a necessary procedure to produce seasoned timber, helping it to burn cleanly. Seasoning can be achieved via several methods, but all methods aim to remove water and prevent damage to the wood.
Natural Seasoning of Timber
- Water seasoning is the process in which timber is immersed in water flow which helps to remove the sap present in the timber.
- In the process of air seasoning, timber logs are arranged in layers in a shed.
- In the case of chemical seasoning, timber is stored in a suitable salt solution for some time.
Seasoning Firewood
To season firewood properly, stack it in a place where the sun can warm it and the wind can blow through it. A single row exposed to the sun and prevailing winds are best–as the sun heats and evaporates the water from the wood, the wind whisks it away. The season for a season.
Unseasoned Timber
Unseasoned timber, or green timber, has not yet dried thoroughly enough to be considered seasoned. The moisture content of unseasoned timber can range from as low as 25% to as high as 100%. Whereas the moisture content for seasoned timber, particularly for South-East Queensland, ranges from 10% to 15%.
Seasoning of Lumber
Seasoning is the process of drying timber to remove the bound moisture contained in the walls of the wood cells to produce seasoned timber. Seasoning can be achieved in a number of ways, but the aim is to remove water at a uniform rate through the piece to prevent damage to the wood during drying (seasoning degradation).
Two Types of Wood Seasoning
There are two main ways of seasoning timber. the first is the natural method where the timber dries naturally by air. The second is kiln drying, where the wood is circulated and the temperature of the wood is controlled by a kiln.
Seasoning of Teak Wood
You need to cut to standard sizes and store them with good airflow (“wood stacking for air seasoning” ). You need to leave the cut pieces at least for 2-3 years for sections of 3″-4″ thick ( standard 25mm thick needs 3-6 months based on wood type ).
Kiln Seasoning
In seasoning. In dry-kiln seasoning, the wood is placed in a structure in which heat, humidity, and air circulation are carefully controlled by fans and steam pipes. As adjuncts to air and kiln seasoning, salt or urea may be impregnated into the wood to make it season more easily.
Air Seasoning of Timber
most common seasoning methods are air seasoning and dry-kiln seasoning. In air seasoning, the boards are stacked and divided by narrow pieces of wood called stickers so that the air can circulate freely about each board. The stack is slanted to facilitate the drainage of rain.
Water Seasoning of Timber
Water seasoning is the process in which timber is immersed in water flow which helps to remove the sap present in the timber. It will take 2 to 4 weeks of time and after that, the timber is allowed to dry. Well-seasoned timber is ready to use.

What Are The Two Ways Wood Is Seasoned? There are two main ways of seasoning timber. the first is the natural method where the timber drys naturally by air. The second is kiln drying, where the wood is circulated and the temperature of the wood is controlled by a kiln.
Chemical Seasoning of Timber
In the case of chemical seasoning, timber is stored in a suitable salt solution for some time. The salt solution used has the tendency to absorb water from the timber. So, the moisture content is removed and then the timber is allowed to dry. It affects the strength of the timber.
Reasons for Seasoning Timber
Reduction of moisture content along with improving some qualities before the use of wood is called seasoning of timber.
Define Wood Seasoning
Wood drying reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method.
Electric Seasoning of Timber
When the required resistance is reached seasoning, the process is stopped because the resistance of timber increases by reducing moisture content in it. It is also called rapid seasoning and it is uneconomical.
Types of Artificial Seasoning of Timber
Here also different methods of artificial seasoning are there and they are as follows.
- Seasoning by Boiling.
- Chemical seasoning.
- Kiln seasoning.
- Electrical seasoning.
Reasons for Seasoning Wood
To change and improve the properties of wood. To make a correct percentage of shrinking of woods. To make confident use of wood. To reduce the adverse behavior of woods.

Methods of Wood Seasoning
Two methods, progressive and compartmental, are used for kiln seasoning. In a progressive kiln, timber enters at one end and travels on a trolley through chambers with different air conditions to progressively dry the wood. This method produces a constant flow of seasoned timber.
