Speaking of oysters, what is impressive is their fat meat quality. But oyster shells are also valuable. The ancients used oyster shells to build walls, which were called oyster shell walls. As the name implies, it is a wall made of oysters, which is not only beautiful, but also very practical.
Here's what the oyster house does.
In a village in Guangdong, there are some special houses. They are walls made of oyster shells. Because the ancient villages are close to the sea, the output of oysters is relatively high, so humans invented the wall with oyster shells.
Don't look at the oyster shells all over the wall, I think they are definitely worthless, but generally those who can afford oyster shells are rich people. Because although oyster shells are easy to find, it is still very laborious to find many oyster shells of the same size.
Some people will wonder how oyster shells can be piled up without falling off. This is because oyster shells are stuck together by a special thickener. The thickener is made of safe materials, such as yellow mud, brown sugar and steamed glutinous rice.
The oyster shell wall is paved layer by layer, and it will become a very strong wall after a few days of air drying. The whole wall of this building is not made of oyster shells, but the oyster shell wall is built about 50 cm above the ground.
This may be the need to reserve waterproof lines in case it rains and gets soaked by water. Waterproof walls below 50cm are generally made of blue bricks or Shi Zhuan. Building such a house is not only time-consuming and labor-intensive, but also really artistic and shocked by the wisdom of the ancients.
Advantages of oyster shell wall house.
Maybe you think that ancient people built oyster shell houses because they saved money, then you are wrong. Living in such a house is not only warm in winter and cool in summer, but also anti-theft.
The history of oyster shell wall can be traced back to Shang and Zhou Dynasties, and it became popular in Ming Dynasty. In ancient times, people built walls with adobe. It's cheap, but it's easy to dig out.
Later, people found that building walls with oyster shells was not only durable, but also difficult to dig out, which could play a role in theft prevention. It seems that the ancient anti-theft consciousness was also forced out bit by bit.
The secret of the oyster shell wall is that it is warm in winter and cool in summer. The oyster shell on the wall is uneven and inclined at a 45-degree angle. When the sun shines on the oyster shell, it will produce shadows and play a role in heat insulation.
Tilt the oyster shell at 45 degrees, so that it is not easy to accumulate water in rainy days, and rainwater can slide down from the oyster shell. Such a wise building is worthy of being our ancestor.
Building a house with oyster shells is based on local materials and smart construction's artworks. Such an oyster shell house is not inferior in the modern construction industry.
