Today, some painters are faithful to this tradition. Paint is a special kind of substance. Paint is special because it is made of tiny particles of color that float in a liquid instead of dissolving in it. Scientists say that sugar and salt are soluble in water since they completely dissolve. The dissolved mixture is called a solution .
Some substances are different.
For example, look at a bottle of Italian Salad Dressing. You will see some seasonings and other particles floating around. They don't dissolve. Instead, each of these particles is suspended in the oil and vinegar but still visible. This is called a suspension .
