Boiling chips, also known as boiling stones, boileezers or anti-bumping granules, are small, irregularly shaped pieces of material added to liquids to make them boil more smoothly. Boiling chips are frequently employed in distillation and heating. Boiling chips work by providing nucleation sites so the liquid boils easily without becoming superheated.

When a liquid becomes superheated, a particle of dust or a stirring rod can cause flash boiling. This very rapid boiling can be extremely violent and cause reagents to splatter, possibly causing severe burns, ruining an experiment, and damaging equipment. Boiling chips should not be added to liquid that is already near its boiling point, as this could also induce flash boiling.

Boiling chips are typically made of a porous material, such as alumina, calcium carbonate, porcelain or carbon, and often have a nonreactive coating of Teflon. This ensures that the boiling chips will provide effective nucleation sites, yet are chemically inert. In less demanding situations, like school laboratories, pieces of broken porcelain ware or glassware are often used.
