Boiling Points - Gary Stadler

Boiling chips are small, insoluble, stones (the size of grains of rice or sand) made of calcium carbonate, silicon carbide, or carbon (crushed coal) just to name a few. These stones contain many microscopic pores and/or or sharp points which provide a rough surface upon which boiling bubbles can form.
