Boiling chips. A boiling chip, boiling stone, or porous bit anti-bumping granule is a tiny, unevenly shaped piece of substance added to liquids to make them boil more calmly. Boiling chips are frequently employed in distillation and heating. When a liquid becomes superheated, a speck of dust or a stirring rod can cause violent flash boiling.
Boiling chips are added in distilling flasks for distillations or boiling chemical reactions to allow a nucleation site for gradual boiling. This nucleation avoids a sudden boiling surge where the contents may overflow from the boiling flask. Stirring bars or other stirring devices suited for round-bottom flasks are sometimes used. [4]
I have proved by experiment that salt water evaporated forms fresh, and the vapour does not, when it condenses, condense into sea water again. Letting seawater evaporate and condense into freshwater cannot be called "distillation" for distillation involves boiling, but the experiment may have been an important step towards distillation.

The most common way of preventing bumping is by adding one or two boiling chips to the reaction vessel. However, these alone may not prevent bumping and for this reason it is advisable to boil liquids in a boiling tube, a boiling flask, or an Erlenmeyer flask. In addition, heating test tubes should never be pointed towards any person, just in ...
This Fort Worth bottle could be moonshine, but it’s legal. Really.
The reaction flask is heated. Boiling chips within it assist with the calm formation of bubbles of vapor containing the reaction solvent and the component to be removed. This vapor travels out of reaction flask up into the condenser where water being circulated around it causes it to cool and drip into the distilling trap.
A Florence flask/boiling flask is a type of flask used as an item of laboratory glassware and is named after the city Florence. [1] It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat botto
Doritos are a revered snack for many. Now, scientists have found one of the ingredients in the triangle-shaped tasty tortilla chips has a superpower – it can make the skin of mice transparent.
