Vermiculite fire bricks are made from a naturally occurring mineral called Vermiculite which exfoliates when heated. Exfoliated Vermiculite is mixed with an inorganic bonding agent. It is then hydraulically pressed into a mold and then heat cured. The fire bricks are then cut from these molds or boards.
Vermiculite is also used to cover the outer portion of oven domes and hearths. This is done to provide insulation otherwise the heat will escape from the oven. It is recommended that the insulation is of at least 4 inches to slow down cooling.
It is often assumed that Vermiculite carries asbestos which is hazardous for health. However, this is far from the truth. It is the crude Vermiculite that carries asbestos and not the exfoliated version.

What is a Fire Brick?
Fire bricks are slabs made of fire clay that are used to build wood-fired pizza ovens and for lining furnaces, kilns, and fireplaces. The fire clay is made of silica and alumina. The fire brick, also called refractory brick, is used in high-temperature applications because it can withstand high temperatures which is essential if you are using them to build a pizza oven. These bricks offer low thermal conductivity which makes them energy efficient.
Why Use Fire Bricks?
Firebricks are made of a special clay called fire clay. The clay is pressed into a certain shape and then placed in highly heated kilns to achieve the desired hardness. These bricks are also called refractory bricks and are mostly used in high-temperature applications. Many domestic ovens are made of firebricks giving them a classical look. Also, most of these ovens are built at home without professional help.

A: You can easily make a fire pit at home.
Step 1. Create a trench and fill it with mortar.
Step 2. Lay down one layer of bricks.
Step 3. Add more mortar and drop another round of bricks. Ensure that they are firmly pressed against the mortar. Leave ventilation gaps between some of the bricks. This will prevent the fire from going out because of a lack of air and ventilation.
Step 4. Rendering is optional.
Step 5. Paint the pit in a color of your choice. Be sure to use masonry paint. Now, add a layer of gravel to the pit. If you have used render then let it dry before painting the pit.

The temperature control depends on how hard you want the bricks to be.
