The Caldron Traditional Processing

The caldron production process of soap represents the artisan tradition by which man created soap for centuries.

In a first phase called saponification the fats - mainly consisting of glycerides and fatty acids - are converted into sodium salt .

This operation must be carried out so that the resulting product is of good quality and suitable to be subjected to further steps of processing . It is therefore necessary to obtain a pumpable mass easily , generally containing 30% of water, with the least possible amount of alkali and electrolytes, as well as glycerol whose recovery is an economic factor of this process.

The transformation from fats to soap therefore can be obtained with the traditional Caldron Processing (Lavorazione in Caldaia).

Just as in the tradition then, we still produce soap with this ancient and natural method, which ensures the final product top quality and at the same time its cleaning power and a very gentle and soothing treatment for the skin, that after frequent uses becomes soft and more elastic.
