Refractory bricks

Generality

Those who decide to make a barbecue themselves must also know the characteristics of the material to be used. It is not possible to use classic bricks 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.


Features

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 quite smooth and have a pleasant aesthetic appearance. To make a barbecue, and then arrange them one on top of the other, it is not recommended to use classic cement but a specific mortar is preferable which will certainly prove to be more resistant than concrete, 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 advice that the dealer himself will be able to give. Particular attention should be paid to the joints which must be filled perfectly.


Cleaning

Only after all the bricks are in place can they be cleaned with water. Sometimes a solution with muriatic acid is also used which is then rinsed off. It is always advisable to wait a couple of days before use and to avoid ignition at too high temperatures before the bricks have stabilized. As mentioned before, this type of brick is also used for the construction of fireplaces.


How to proceed with the purchase

Before purchasing and then deciding on the required amount of refractory bricks, it is important to create an outline of the barbecue construction project. In fact, only by defining the size can one know the exact number of refractory bricks to buy. The refractory brick, in addition to being used for the construction of a masonry barbecue, is also suitable for creating a 'makeshift' barbecue, that is to light the charcoal or wood directly on the ground, placing two bricks at the ends of this space. they will be used to place the grill on it. Those who love this particular type of barbecue, always keeping a couple of bricks with them, can quickly light a fire and enjoy an excellent barbecue.


Aesthetic aspect

The specific characteristics of the refractory brick concern both their shape and their size, to allow the customer to choose the model that best suits their construction. Depending on the different grain, the refractory brick will have a different appearance that does not affect the quality of the brick, but only the aesthetic aspect. As it was pointed out earlier, it must always be remembered that, since these are particular bricks, they require specific mortars and cannot be bonded with concrete like any other brick. Furthermore, in addition to the characteristic of high resistance to temperatures, it is also used for external uses so it is strongly subject to thermal changes that do not absolutely affect its quality. Cleaning the refractory brick is quite simple, it only takes water to make it return to its original state. It guarantees an unlimited duration over time, moreover its appearance remains almost unchanged.


The cost

The cost of refractory bricks is quite accessible, those who decide to make a barbecue in this way must also be aware of any difficulties they may encounter in the realization, because it is not just a question of concreting bricks. The satisfaction of inviting friends for dinner and preparing a tasty barbecue on a self-made barbecue will certainly be great, to arouse the curiosity of the guests themselves. Every aspect of the barbecue will be customizable, from the external covering to the shelves to have a practical support surface.


Refractory bricks: barbecue: how to use refractory bricks

The refractory bricks are widely used in the construction of many garden furniture but also indoors especially for their functional characteristic, precisely the refractoriness, which makes them resistant to thermal shocks even at temperatures exceeding a thousand degrees.

This characteristic derives from the physical composition of the so-called refractory bricks: completely made with clay to which large percentages of aluminia and silica are added, to make them refractory and physically resistant to high temperatures.

This means that not only do they not react but do not deform at high temperatures.

The refractory bricks are therefore used to make ovens, barbecues, fireplaces, flues, stoves or boilers.
