A firepit is a contained outdoor space where you can build a fire. They are usually made out of metal, stone or brick. The most important part of a firepit is the liner, which is what contains the fire and protects the pit from the heat.
There are three main types of materials that are used to coat firepits: fire brick, ceramic and cast iron.
Fire brick is the most common type of material used to coat firepits. It is made out of refractory ceramic material and is designed to withstand high temperatures. It is also very durable, which makes it a good choice for a firepit liner.
Ceramic is another type of material that can be used to coat firepits. It is a good choice because it is resistant to heat and flame. However, it is not as durable as fire brick and can crack over time.
Cast iron is the third type of material that is used to coat firepits. It is very durable and can withstand high temperatures. However, it is also very heavy, which can make it difficult to move the firepit.
