About Marble Testing

• Marble has been quite popular and affordable
  option for kitchen countertops. Off late, there
  has been an inherent misunderstanding about the
  existing radiation levels in natural granite
  being used for kitchen countertops, bathroom
  mirror, flooring etc.
• Water absorption
• The amount of water that a refractory can
  absorb is measured by the water absorption test.
  The results of water absorption tests are used
  for quality assurance.
• Mohs Hardness
• This test helps in determining the
  hardness of rock. Because granite is a rock
  composed of multiple minerals, only crystals of
  specific minerals within the granite would be
  tested for hardness.

• Breaking Strength
• Rocks are considerably weaker in tension
  than in compression. Characterizing tensile
  strength of rocks thus is of great importance in
  many engineering and geophysical applications.
  Tensile strength is defined as the failure of
  stress.
• Frost Resistance
• Ceramic tile frost resistance is defined as
  the ability of ceramic tile to withstand
  freeze/thaw conditions with minimal effect. The
  frost resistance of ceramic tile is dependent on
  the tile's porosity and water absorption levels.
  Frost damage can occur when the variety of
  ceramic tile absorbs moisture through its pores,
  causing the water to freeze internally when
  temperatures drop. Since water expands when it
  freezes, tension is then exerted inside the body
  of the ceramic tile. This internal pressure may
  become high enough to cause cracks in the ceramic
  tile.
