Porcelain and ceramic are both popular choices when it comes to tumbling media, but there are some differences between the two. Porcelain is traditionally made from a combination of clay and other materials, while ceramic is made from a mixture of materials that often includes clay, feldspar, and silica.
One of the primary differences between the two is that porcelain is typically harder and more dense than ceramic media. This means that it can be more effective at removing difficult burrs and creating a smooth, polished surface. It is also less likely to break down over time, which can be beneficial for those who use their tumbling media frequently.
Ceramic media, on the other hand, is often more affordable and can be less abrasive than porcelain. This can make it a good choice for those who are working with delicate or thin materials that may be more easily damaged by harder media. Ceramic also tends to be lighter and easier to handle, which can be more convenient for some users.
Ultimately, the choice between porcelain and ceramic tumbling media will depend on your specific needs and preferences. It is important to consider factors such as the materials you will be working with, the level of abrasiveness required, and your budget when making your decision. Both types of media can be effective for tumbling, so it may be a matter of personal preference as to which one you choose.
