Have you ever heard of porous ceramics? No? Well, don’t fret, because you’re not alone. Even some of the most experienced potters may not know the difference between regular ceramics and porous ceramics. So, what are porous ceramics and how do they differ from regular ceramics? Let’s explore.
First of all, let me explain what ceramics are. Ceramics are a type of material made from clay, which is then hardened by firing it in a kiln. This process makes the material sturdy, durable and functional for various purposes. Ceramics are used for making kitchenware, pottery, decorative items, and even construction materials.
Now, regular ceramics are exactly what they sound like they are solid, dense and non-porous. In other words, they don’t have any holes or openings in them. They are made by compacting the clay to make it denser and smoother, which results in a finished product that’s more resistant to water and other external elements.
On the other hand, porous ceramics are made using a different process altogether. Porous ceramics have tiny openings in them which allow air, water, and other substances to pass through them. They are made by adding certain materials to the clay which creates the porous structure when fired in the kiln. This structure makes it possible for the ceramic material to absorb water and other substances, which makes them useful for specific applications that regular ceramics cannot handle.
There are many advantages to using porous ceramics. Aside from their ability to absorb substances, they have a unique texture and appearance that adds character to your work. Because they are more absorbent, porous ceramics can be used for making wicks for oil lamps, oil diffusers, and even plant pots, since they can help to regulate the moisture content of the soil.
Another advantage of porous ceramics is their ability to filter impurities, making them ideal for use in water filtration systems. They are used in filter cartridges that work in a similar way to a coffee filter, where the pores or holes within the ceramic filter out impurities, leaving behind clean water.
One of the biggest differences between regular ceramics and porous ceramics is the manufacturing process. Porous ceramics require specific materials and additives to be added to the clay before it’s fired, which results in a unique porous structure. Regular ceramics, on the other hand, are made by just simply molding and forming the clay before firing it in the kiln.
Another difference between the two is the texture of the finished product. Porous ceramics have a rougher texture and unglazed finish, which adds to their unique appearance. Regular ceramics, on the other hand, can be glazed to give them a smooth and shiny finish.
When it comes to price, porous ceramics are more expensive than regular ceramics. This is because of the added materials required to create the porous structure, as well as the additional steps involved in manufacturing them.
In conclusion, porous ceramics are a unique type of ceramic that not many people are familiar with. Their ability to absorb substances and filter impurities makes them ideal for specific applications. They are made using different materials and additives than regular ceramics, which results in a unique porous structure and texture. So next time you’re in the market for some new ceramics, don’t be afraid to give porous ceramics a try you might just be surprised by the results!
