A concrete mold allows people to make long-lasting works of art.
About as far back as there have been signs of humans, there have been signs of the humans' need to be creative.
It is perhaps instinctual for us to, for whatever reason, alter our environment for no other reason than to change its looks.
We enjoy these changes, to make things more, beautiful, interesting, and to reflect ourselves.
People sometimes like their works of art to be solid and long lasting, which why they are often made of stone.
The molds for concrete may be used for making statues.
A lot are made of latex.
A person can get liquid latex.
They may need a large amount and it is not cheap.
Then they take an item like a stone statue already perfected, or some other solid object, and go through a process of dipping it into latex or coating it in some other way.
Strong molds involve several coats.
After the latex is completely dry, it is cut in half and the object removed.
Now each half of these molds can be filled with the concrete and strapped tightly back together until the mixture dries and you have another statue.
Some people have made home businesses of doing this.
Concrete molds are also used to make decorative stepping stones.
A person can buy these molds in almost any shape.
They may be simple wooden frames that one pours a mixture into, and then the frame is removed after the mixture is dry.
Some are made of very strong plastic or even metal and may resemble a flat decorative cake pan.
People can make different shaped stepping stones using these.
Some are square with slightly raised places to form a shape, like flowers, or some kind of animal.
