History of Pumice

ELEMENTS

  • Pumice is formed when lava containing high levels of water and gases erupts from a volcano

  • Pumice is a igneous rock formed when molten rock (magma) cools and solidifies

  • Is formed when hot lava mixes with water, cools rapidly and depressurization creates bubbles by lowering the boiling point of the lava.

  • The cooling of the rock below melting point produces a solid.
  • Sodium Fluoride (NaF): Ionic bond, reaction between a

metal and non-metal

  • Glycerin: thick colorless liquid, sweet taste

  • Quartz- made up of Silicon (Si) & Oxygen (O)

covalent bond-sharing of electrons between two non-metals

  • Sodium Silicate-(Na2SiO3) AkA "water glass" or "liquid glass"
