Those who decide to make a barbecue themselves must also know the characteristics of the material to be used. Classic bricks cannot be used for this specific function, because they would not prove to be resistant enough to high temperatures. The refractory brick, on the other hand, has its own characteristics that make it specific for use in this sector.
There are basically two types of brick: red brick and yellow brick. The red brick is certainly the most common one, resistant up to 1000 degrees centigrade, while the yellow or white brick also resists up to 1300 degrees centigrade. They differ from normal brick because their grain is very fine and compact, thanks to the type of processing to which they are subjected, they are rather smooth and with a pleasant aesthetic appearance. To make a barbecue, and then arrange them one on top of the other, it is not advisable to use classic cement but it is preferable to use a specific mortar which will certainly prove to be more resistant than cement, which in contact with these very high temperatures would not resist thermal shock . Before being used i refractory bricks they must be wet for a long time. These are specific tips that the dealer himself will be able to give. Particular attention must be paid to the joints which must be perfectly filled.
