Bricks are made with the two most abundant materials on Earth: clay and shale. These two materials are then put in a furnace, called a kiln, and heated to 2,000°F (approximately 1,100°C). By a chemical process (vitrification), the materials fuse together and form bricks.Know More
Concrete bricks, gray bricks similar to clay bricks, are not really bricks, even though people call them such on a regular basis. Concrete bricks are significantly easier to break that clay bricks.
Due to the longevity of clay bricks, some of the American colonial buildings still stand today. A few examples are Virginia's St. Luke's Church (est. 1632), the Boston State House (circa 1713), and Philadelphia's Independence Hall.Learn more about Solutions & Mixtures

Iodine solution is made by mixing iodine into a mixture of potassium iodide; this mixture is commonly used to check for starch. Iodine solution is also known as povidone and is used to kill bacteria and treat infections and mild cuts.Full Answer >
A precise but simple explanation of the difference between a mixture and a solution is that a mixture is a substance made of other substances that are mixed but not joined together, while a solution is a substance made of two or more substances that do join together. If the kids are older, it should be noted that a chemical reaction takes place to create a solution and that no such reaction occurs in a mixture.Full Answer >
Sulfur is made at very high temperatures in the depths of massive stars when the nuclei of silicon and helium fuse. On Earth, sulfur is found in its free state near volcanoes and hot springs. It is also brought to Earth via meteorites.Full Answer >
