Wooded gazers and wooden doors have been around for thousands of years, but the origins of the popular doors, also known as wooden gizmos, are unknown.
Now, researchers have identified three key ingredients that give wooden doors their signature shape: the wood, the shape, and the moisture content.
The researchers, led by Dr. J. Craig Wright of the Smithsonian Tropical Research Institute, analyzed three key components of the wood of the door: the grain, the density, and moisture content, which was determined by the weight of the material.
They then compared these three components to an existing wooden giza door and discovered that both the grain and the density were very similar to each other.
This suggests that the wood was used to create the door, and not just the door itself.
According to the researchers, the moisture level of a wooden gazi door was lower than that of a typical wooden door, which is good news for moisture-wasting wood, since wooden doors are much less likely to dry out than other materials.
“Wooden gazes and wooden door design are similar, but it is the density of the moisture that is critical,” said Wright.
“It is very important that a door that is not made of wood be durable and that it be moisture-resistant.”
To find out what the specific ingredients were that made the wood appear different, Wright and his colleagues analyzed the humidity levels in the air.
The researchers found that a wood door with a lower humidity level would have a lower strength than a wood giza.
However, a wood window, which has a higher humidity level, would have more strength than either.
The scientists then determined how the moisture was absorbed by the door and doorboard.
In order to determine how much moisture was transferred to the wood and door, they used a process called “molecular modeling.”
The researchers created a model that simulates how the different ingredients in a wood are absorbed by a piece of wood.
They used the process to compare the moisture contents of different materials.
To determine how the two materials changed in terms of moisture content and strength, the researchers tested the door to see how it changed over time.
They found that the density decreased over time, but a wood wall also experienced a decline in strength, while a wooden door remained unchanged.
“The wood wall was much more susceptible to moisture than the wood gazey, which means that it would be more likely to absorb moisture than any other material,” Wright said.
The results show that the moisture in wood is important to the strength of a wood and is a major component of the strength and durability of a door.
The next step is to figure out which materials are most important to this process.
“We have not yet identified the ingredients that make wood doors strong,” Wright continued.
“That will take a lot more research.”
