What is Burnt Brick?
Burnt brick refers to a type of brick that is formed in molds, laid out to dry for some time, and then stacked to form a kiln, where they are burned to harden, making them more durable. The production of burnt bricks involves the use of kilns and possibly furnaces for metallurgy, indicating a level of advanced technology and urbanized civilization.
Overview of Burnt Bricks
Burnt bricks have been used for centuries, with evidence of their use dating back to Mesopotamia between 5000 and 4500 BC. The use of burnt bricks has been a hallmark of advanced civilizations, including the Indus civilization, where they were used to build structures that could withstand the elements and last for centuries.
Production Process
The production of burnt bricks involves several stages, including mixing, molding, drying, and firing. The mixture for burnt bricks typically consists of alumina, calcium silicate, iron oxide, lime, and magnesium, which are combined with clay and water to create a workable mixture.
Quality of Burnt Bricks
A good quality burnt brick should be sound in texture and shape, hard, and not break easily, with its strength depending on the clay composition, manufacturing techniques, and physical shape and dimension of the bricks.
Benefits of Burnt Bricks
Burnt bricks have several benefits, including being fire-resistant, solid, and insect-proof, making them a popular choice for construction projects. They also have a low insulation value due to their high thermal mass, which aids in heat retention.
FAQs
1. What is the difference between burnt brick and baked brick?
Burnt bricks and baked bricks differ in their production process, with burnt bricks being formed in molds and then burned in a kiln, while baked bricks are made using a more advanced brick-making technology.
2. What are burnt bricks made of?
Burnt bricks are made from a mixture of alumina, calcium silicate, iron oxide, lime, and magnesium, combined with clay and water.
3. What is the quality of burnt brick?
A good quality burnt brick should be sound in texture and shape, hard, and not break easily, with its strength depending on the clay composition, manufacturing techniques, and physical shape and dimension of the bricks.
4. What are the benefits of burnt bricks?

5. What is the difference between burnt brick and concrete blocks?
Burnt bricks and concrete blocks differ in their production process, with burnt bricks being formed in molds and then burned in a kiln, while concrete blocks are made from a mixture of cement, sand, and aggregate.
6. Why is fire brick so expensive?
Fire brick is more expensive because it is made to last longer and is able to withstand higher temperatures.
7. What is the best quality brick in the world?
The best quality brick in the world is considered to be burnt clay bricks, which are known for their strength, durability, and aesthetic appeal.
8. How many types of burnt bricks are there?
There are four classes of burnt clay bricks, which dictate the overall quality, strength, appearance, and shape of the brick.
9. Where did burnt brick come from?
Burnt bricks originated in Mesopotamia between 5000 and 4500 BC, where they were used to build structures that could withstand the elements and last for centuries.
10. What are the three types of bricks?
The three main types of bricks are facing bricks, engineering bricks, and common bricks.
11. What are under burnt bricks called?
Under burnt bricks are called pilas, which are yellow in color and can be used as surkhi.
12. Are baked bricks waterproof?
Baked bricks are less affected by long-term water exposure, making them a popular choice for construction projects in areas prone to flooding.
13. What is the color of burnt brick?
Burnt bricks are typically reddish in color, although they can vary in shade depending on the type of clay used.
14. Are bricks baked in a kiln to make them?
Yes, bricks are baked in a kiln to make them strong and durable.
15. Are fire bricks expensive?
Fire bricks can be expensive, but they are also durable and able to withstand higher temperatures, making them a worthwhile investment for many construction projects.
