Perlite or Vermiculite? The Difference Explained in 2 Minutes
Perlite is a type of volcanic glass that has been heat-treated where it then puffs up into small white balls. Perlite is lightweight, sterile, easy to handle and has no smell. It absorbs water but is also porous as the water drains freely away. Perlite is full of air pockets and is primarily used by gardeners to aid with drainage. Use perlite:

Effects of high magnetic field strength and direction on pearlite …
The effect of a magnetic field on the formation of pearlite in a Fe–0.12%C steel was investigated. The results show that pearlite colonies elongate and align along the field direction, and that this tendency increases with increasing magnetic field strength. The possible preferential nucleation of ferrite between existing ferrite grains aligned along …
