A lollipop is a type of sugar candy usually consisting of hard candy mounted on a stick and intended for sucking or licking. Different informal terms are used in different places, including lolly, sucker, sticky-pop, etc. Lollipops are available in many flavors and shapes.

Although the main functional ingredients of a lollipop are quite simple, the actual process of making this product is where things start to get complicated. It has already been stated that a glassy amorphous structure is a non-crystalline solid. However, the formation and physical state of this glass has a lot of chemistry and physics behind it. The first step in making lollipops after mixing the main ingredients is the heating process. During heating, the molecules increase in their translational mobility and therefore become liquid-like.[11] Although it can be found that many hard candies are heated to about 310˚F, the temperature that the solution is heated to is dependent on the specific volume and contents of the mixture. After heating is complete, the solution can then be cooled. The final cooled solution is a supersaturated due to the fact that the moisture content drops to below 2%. Supersaturated or supercooled liquids are also formed due to the fact that crystallization is being inhibited. They are unstable because crystallization is a favored reaction in this case. During the cooling process, the most important physicochemical characteristic of lollipops is occurring. This process is called glass transition.
