What is Casting?
Casting is like making a copy of something by pouring a soft or liquid material into a mold (a special shape), and then letting it harden so it looks just like the mold.
Imagine you made a model using clay and you want to make many copies of it. Instead of sculpting each one, you create a mold from the model, pour a liquid into it, and let it dry to get the copies.
How Does Casting Work?
- Create the Mold: First, you make a mold. This mold has the shape of the thing you want to copy. It can be made from materials like rubber or plaster.
- Pour the Material: Next, you pour a soft or liquid material into the mold. This could be melted metal, plaster, or even liquid plastic.
- Let it Harden: You wait for the liquid to harden or cool down inside the mold.
- Remove the Cast: Finally, you take off the mold and see the new object that looks just like the mold shape!
Examples of Casting:
- Making metal coins by pouring melted metal into coin-shaped molds.
- Making toy figures by casting plastic or resin.
- Creating plaster statues or decorations.
Why is Casting Useful?
Because it allows people to make many copies of the same shape easily and quickly without sculpting each one by hand.
