Beakers are great for mixing, measuring, and pouring liquids. They are most commonly seen in a science lab, but they do have other uses. Many people use them in cooking and baking, or for various DIY projects. They can even be used as cups. The 50mL beaker works well as a large shot glass!
All beakers are made from 3.3 borosilicate glass, which is resistant to thermal shock. Borosilicate glass can be heated and cooled quickly without cracking or breaking, unlike most other types of glass.
