How Bricks Are Made: A Step-by-Step Manufacturing Process
Overview
The provided text describes the brick-making process, starting from clay extraction to final delivery. It's a seven-step process that includes digging clay, breaking it into smaller pieces, mixing it with water and sand, molding or cutting the mixture into brick shapes, drying the bricks, heating and cooling them, and finally, packing and delivering the finished products. The description provides a clear, sequential account of each stage involved in transforming raw clay into usable bricks.
Key Features
- Begins with raw material extraction using a digger.
- Involves breaking down clay and mixing it with water and sand.
- Utilizes molding or wire-cutting techniques to shape the bricks.
- Includes a drying process to remove moisture.
- Employs heating and cooling stages at controlled temperatures.
- Concludes with packing and delivery to customers.
Our Review
This essay provides a solid overview of the brick manufacturing process. While the sequence of steps is clearly outlined, the writing could benefit from more sophisticated vocabulary and sentence structures. Adding more detail about the purpose of each step (e.g., why specific temperatures are used in the heating process) would enhance the essay's depth and demonstrate a greater understanding. We believe that with some refinement in language and detail, this response could achieve a higher band score.
Student Submission
The illustration depicts how the bricks can be built in the manufacturing industry. Overall, it is clear that the 7-step process of building bricks commences with digging the mud and collecting the clay and ends with delivering the bricks to the customers. To begin, the clay used to build the bricks is dug up from the ground by a large digger. The clay is then placed in a metal grid to break up the clay into smaller pieces. A roller assists to move the smaller pieces of clay. Next, water and sand are added to the small clay, and this mixture is turned into bricks by either placing it in a mould or using a wire cut. Following this stage, the moisture bricks are placed in a drying oven to dry for 1 to 2 days. In the subsequent stage, the dried bricks go through a heating and a cooling process. They are heated at moderate and high temperatures ranging from 200 degrees Celsius to 1300 degrees Celsius, followed by a cooling process in a cooling chamber for 2 to 3 days. Finally, the bricks, which are cooled, are packed and delivered to various customers.
IELTS Essay Assessment
1. IELTS Writing Score: 6/9 ■■■■■□□□
2. Score Breakdown:
- Task Achievement: 7/9 - The essay adequately describes all stages of the process shown in the diagram. The information is presented logically, although some minor details could be added for a more comprehensive description.
- Coherence and Cohesion: 6/9 - The essay uses cohesive devices (e.g., "To begin," "Next," "Following this stage," "In the subsequent stage," "Finally") effectively to link sentences and paragraphs. However, the structure could be improved by using more sophisticated linking words and phrases to show a clearer progression of ideas. The overall flow is good but lacks a sophisticated structure.
- Lexical Resource: 6/9 - The vocabulary is appropriate for the task, although the range could be broadened. There's a reliance on simpler vocabulary choices. More precise and academic vocabulary would improve the score.
- Grammatical Range and Accuracy: 6/9 - The grammar is mostly accurate, with only minor errors. Sentence structures are relatively simple, and a wider range of grammatical structures would enhance the score.
3. Error Analysis:
-
Vocabulary Errors:
- [
moisture bricks] -> [ dried bricks/bricks ] : The term "moisture bricks" is unusual and unclear. "Dried bricks" is more accurate after the drying process.
- [
-
Grammar Errors:
- [
The clay is then placed in a metal grid to break up the clay into smaller pieces.] -> [ The clay is then placed in a metal grid to break it into smaller pieces.] : Avoid unnecessary repetition of "clay." Using "it" is more concise and elegant.

4. English Model Essay:
The diagram illustrates the seven stages involved in brick manufacturing. The process begins with the extraction of raw materials and culminates in the delivery of finished products to consumers.
Initially, clay is excavated from the ground using a large digger. This clay is then transferred to a metal grid where it is pulverised into smaller fragments. A roller facilitates the movement of this processed clay. Subsequently, water and sand are incorporated into the mixture, which is then formed into bricks either using moulds or a wire-cutting machine.
The newly formed bricks are then placed in a drying oven for one to two days to remove excess moisture. Following this, the bricks undergo a high-temperature firing process, reaching temperatures between 200°C and 1300°C, before being cooled gradually in a controlled chamber for two to three days. Finally, the cooled bricks are packaged and distributed to various customers. The entire process demonstrates a systematic approach to transforming raw materials into a durable building product.
