What is the difference between Lava and Pumice?

Lava is molten rock that was formerly magma. Lava is formed as a result of a volcanic eruption in which magma is rushed up to the surface of the earth. The moment the magma reaches the surface, scientists call this Lava. This whole process is very fascinating. The hidden secrets that lie within Lava are endless. Did you know that lava is so dense in substance that it flows very slowly? Come take a look at National Geographic’s video of lava flowing across earth’s surface. 



When the lava that is erupted from the volcano is high in water and gas, pumice is formed as the gas tries to rapidly escape. This chemical reaction creates the porous and airy look of the rock known as Pumice. Pumice is generally lightweight that breaks down over time. 

There are a few main differences between Lava and Pumice

  • Lava fines are more firm than Pumice. The chemical composition of lava makes this rock very hard and sturdy. Pumice has a lot of holes or pores in the rock, making it easier to be broken down and dissolve over time. 
  • Lava fines will not change in size. A large amount of force needs to be applied in order to break down lava. Once it is broken down to the ideal size, this size doesn’t change over time, giving a consistent and reliable size of the lava fines. On the other hand, lightweight pumice does not require a lot of force to break down leaving you with pumice powder that is not consistent in size and inconsistent benefits. 
  • Both Lava and Pumice are good for your drains. The porous nature in both of these rocks makes it safe for your drains. Especially compared against microplastics, lava and pumice are good alternatives. Recent studies on microplastics and its effect on both humans and the environment has quickly become a rising topic amongst scientists. 
  • Pumice has more Silicon content than Lava. Think of it this way, the more porous the rock is, the more silicon content. Now, this can be good and it can be bad. There are multiple benefits for SIlicon such as healing wounds and repairing skin, however, these benefits disappear the moment you wash it away. That is, if you can wash it away properly. Silicon is known to get stuck in your pores because it breaks down so easily. 

Are Lava Fines better than Pumice Powder?



Now, looking at these differences, what does this mean? Lava and Pumice are both ok to wash down the drains but Pumice is more likely to remain in your skin and break down. In conclusion, the optimal benefit that lava fine and pumice can provide is the exfoliation agent. If you plan on using up your pumice powder product within a short timeframe, you don’t need to worry about the particles breaking down, but if you are relying on consistent and long-term results from your product, try using product that contains lava powder.
