Pumice is more porous than perlite, with a porosity of 80-90%. This makes it a better choice for plants that need less water around their roots. Perlite, on the other hand, has a porosity of 50-70% although it is still good enough for improving drainage in potting mixes. Water retention. Pumice has a higher water retention capacity than perlite.
The industrial processing of perlite involves mining the raw material from volcanic deposits, followed by crushing and grinding to achieve the desired particle size. After processing, perlite is subjected to intense heat at temperatures of around 900-1100°C (1652-2012°F) in a furnace.

Use perlite to aid drainage. Succulents and other plants sensitive to moist soil benefit from having perlite added to the potting compost. The perlite will trap air in the compost and encourage water to drain through, ensuring the plant's roots will never sit in damp soil. Mix perlite with compost at a ratio of around 1:4.
Perlite is one of the most overlooked insulating materials, especially as it o˜ers numerous advantages over other organic and inorganic insulation materials. In an era of growing concern for the impact that building materials and products have on the environment, the choice of which materials to use is increasingly informed by relative performance
Perlite is a volcanic glass that is often used in gardening due to its lightweight, porous nature that aids in healthy plant development. "It is made from a type …
While processing raw perlite (cutting, grinding, and fractionation to various sizes), large amounts of powder are collected and stored as waste. ... makes it an ideal choice as a lightweight ...
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. Perlite is one of nature's most versatile and efficient minerals. Its unique characteristics of being lightweight ...
Perlite is a volcanic glass that has undergone a natural process of rapid heating and cooling. It is composed primarily of silica, along with varying amounts of alumina, iron oxide, and other trace minerals. The unique structure of perlite is what sets it apart from other materials.
Perlite is an excellent soil conditioner and a good choice for potting mixes that contain plants that are infrequently repotted. It will be beneficial to apply it once a year to keep your soil light and loose for an extended period of time. Perlite can be used up to 3 to 1 per container for container gardens, potted plants, and raised beds.

Vermiculite is a crystal actually originates from clay, is almost black and shiny, with light colored veins across the stones. Perlite is actually a type of volcanic glass is off white in color, have a rounded appearance, with soft edges. Vermiculite is better at holding water. Perlite is better for aeration.
Perlite is a non-renewable resource. The world reserves of perlite are estimated at 700 million tonnes. [4] The confirmed resources of perlite existing in Armenia amount to 150 million m 3, whereas the total amount of projected resources reaches up to 3 billion m 3. [5] Considering specific density of 1.1 ton/m 3 confirmed reserves in Armenia ...
For seeds or plant cuttings that are prone to rot, perlite can be a great choice for germination and rooting. Perlite's moisture-absorbing properties keep the seeds or cuttings dry without parching them and offer plenty of access to oxygen.

If you're trying to break up hard clay soil in a garden bed, I recommend raking a 2-inch layer of perlite into the top 6 to 12 inches of soil, then add 2 to 3 inches of quality compost and see how it goes from there. Remember that perlite doesn't decompose, so once you add it, you're permanently changing the structure of your soil.
Perlite is a form of volcanic glass that has been superheated until it expands. This provides a light and airy structure that is ideal for retaining water, nutrients and oxygen in hydroponic systems. Despite its resemblance to Styro perlite is not made from plastic. It's a natural material made from a specific form of volcanic glass.
Perlite is the active ingredient for the mechanical insecticide made from volcanic rock, which can be expanded (when heated to 760–980 degrees Celsius) and then processed (by drying and grinding) to obtain a fine white powder.
