Ceramic tile has been around in various forms going back hundreds, if not thousands, of years. You will see different methods depending on if they are handmade or not. Hand-making ceramic tile goes all the way back to the time of Egyptian pharaohs, and today the tradition continues.
Every tile manufacturer is going to have their own recipe, but the materials that go into the clay for ceramic tile are all natural elements that are found in the earth. At first, the clay mixture is roughly 30 percent water to help hold the ingredients together. After drying, the moisture content drops down to around 6 percent, and after being fired in the kiln, the moisture level drops even lower.
After being dried out, the ingredients become a dust that is pressed under a massive amount of pressure into the desired shape. This where unique or basic shapes are formed. From here, ceramic tile is glazed before being fired or baked for an extended period of time, reaching temperatures in the thousands of degrees.
