What is the purpose of boiling stones and why wouldn't you add one to an already hot liquid? Thanks for the help.
Boiling stones are small, inert substances that are added to a liquid to promote even boiling. They have a rough surface that provides nucleation sites for bubbles to form, preventing the liquid from boiling over.
The most commonly used boiling stones are porous materials such as pumice, granulated cork, or glass beads. These materials are inert and do not react with the liquid being boiled.
Boiling stones work by providing nucleation sites for bubbles to form in a liquid. This helps to prevent the liquid from boiling over and promotes even boiling. The rough surface of the boiling stones creates tiny pockets of air that act as starting points for bubbles to form.
Boiling stones should be used when boiling liquids that have a tendency to foam or boil over. They are commonly used in chemistry labs when heating solutions or reactions, as well as in cooking to prevent liquids from boiling over.
Boiling stones should be cleaned and stored properly to ensure their effectiveness. They can be cleaned by rinsing with hot water and drying before use. After use, they should be thoroughly cleaned and stored in a dry place to prevent any bacterial growth.
