  • Soil porosity

    Soil porosity. Soil void ratio (e) is the ratio of the volume of voids to the volume of solids: Where V_v is the volume of the voids (empty or filled with fluid), and V_s is the volume of solids. Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil.

  • How To Choose A Terracotta Pot By Its Porosity

    So generally speaking, if the clay is high fired it will be far less porous. This is advantageous for a freeze/thaw condition. If the clay is low fired, or under fired it will be porous and best for releasing or absorbing water. So the bottom line is that the level of porosity you should seek depends on your intention for use of the ceramics.
