A glass stirring rod is a common piece of lab equipment used to mix or stir liquids and chemicals. These rods are thicker than a typical drinking straw, have rounded ends and are made from a special type of laboratory glassware called borosilicate. This glass is less affected by thermal stress and has a very low thermal expansion point, so it is less affected by heat than metals are.
