Why is a refractory terracotta oven the best option?

The quality of a material can be recognized at a glance; if you look closely at the picture above, you will notice the difference between refractory terracotta and a material of the type normally used for building ovens, which, more often than not, is mixed with concrete. The differences are striking when comparing them side by side.

The differences are striking when comparing them side by side.
But what is the main difference between these two materials?  It mostly depends on the grade of purity of the clays chosen as the main terracotta ingredient, besides the fact that they are blended and processed using refractory material derived from pure, certified aggregates, with no addition of impure materials that could be hazardous to human health.
Terracotta is compact and dense, with a completely natural, pasty shade. It does not crumble and as such, does not release hazardous particles into food. Conversely, other types of materials are made from impure mixtures and rarely certified for food use. In addition, they need to be painted to give them a natural look.
Refractory material is able to withstand the highest temperatures, unlike common terracotta used for making pots, and does not give rise to any chemical interaction with the substances - food in the first place - with which it comes into contact. That is why refractory terracotta is a healthy option. Furthermore, it conveys a particular fragrance to food without contaminating it. Ideal for ovens designed for food use, refractory terracotta is known for its ability to warm up quickly based on the thickness of the artifact, and cool down slowly thanks to its thermal insulating property. This facilitates the cooking process and assures great energy savings. In fact, a terracotta oven retains heat for a long time and you can still cook a meal in it the day after without having to rekindle the fire.  
The superiority of a product is assured, above all, by the raw material of choice. Goti refectory terracotta ovens are completely reliable, accurately crafted with strong attention to detail and high-quality.
