The barbecue

In our modern society there are now very few things that can boast (even if things do not boast, but it is a necessary personification to expose the matter in the best way) of entertaining a large number of people and being able to be considered healthy at the same time. and healthy. In fact, today’s young people and people in general who grant their lives moments of happiness in our time think more about doing it with excesses than with anything else; drugs, alcohol, Saturday night car races are just some of the examples we could bring to this cause. However, one of the things that can really boast the name of healthy fun is the barbecue: it is an activity that is done by adults as well as by young people, by all those who love to be with friends and family and who love to cook and eat in their company between a chat and another. The origins of the barbecue are ancient, because it could be considered as an embers or a mobile and self-propelled hearth; its modern diffusion is instead to be attributed to the culture of North America, then launched in the world by the Hollywood industry of films and advertisements.

Origin and diffusion


As we have mentioned, the origin of the barbecue is to be found in the historical cultures of Mediterranean Europe, where in the popular tradition the custom of using the hearth and the embers to cook food on holidays is still alive. Not only that, these inevitable tools in the houses of the past, were also used to cook in the fields or pastures, when there was no possibility and no time to return home for lunch. In short, it seems evident that the primary origin of the barbecue is on this side of the Atlantic Ocean. Now it is difficult to establish who invented, thought, decided first to put wheels on a firebox with embers or in any case to make it mobile; the fact is that the American people must be acknowledged for having brought this solution to success, interpreting it at its best and managing to draw that benefit from the point of view of harmony and being comfortable with others that we see in typical American films and that we tried to describe before. It all started around the seventies of the last century: the United States of America was experiencing a period of economic and cultural modernization, which fascinated the rest of the world thanks to the fact that all other peoples could know what happens in that wonderful culture. through the films and TV series that the powerful national film industry was able to produce. And it is precisely in these films that the myth of the barbecue was born, as a deterrent for the union of families, friends, neighbors who lived moments of joy and harmony around a couple of grilled steaks.

Construction of the barbecue

The construction of the barbecue, that is an object that from the functional point of view is quite simple but which from the point of view of cultural and social importance plays a role of the highest order, is not a difficult operation, but which requires knowledge and experience. . First of all, since an object that must bring serenity and joy must never cause trouble and sorrow, the main point of the design and then of the construction of the barbecue must be that of the correct conveyance of heat towards what it needs (the food to be cooking) keeping it away from what could experience it as a danger (the human body, primarily the hands). Secondly, you should pay attention to its static safety, that is to say that balance of forces and weights that must guarantee the barbecue to stand up even for some extraordinary event such as strong wind or an accidental impact. This must be true both for self-propelled barbecues and for fixed brick barbecues, which are often self-built and that is why some experience is required.

Refractory bricks

The first characteristic that we have exposed in the previous paragraph, that is the correct conveyance of heat, seems to us absolutely the most important thing and this is what we will take into account now. To allow the fire chamber (in the case of a closed barbecue) to remain isolated from the outside world, both to avoid cold currents that could cause the food to cook poorly and to prevent excessively high doses of heat from escaping for which it is questioned the safety of those near the barbecue, refractory material, specifically bricks, are often used for the construction of the walls and bottom of the barbecue. Refractory bricks are particular bricks that are made with materials that do not transport heat, that is, if they receive heat from one side, they cannot be crossed by it:
