It is the product resulting from the calcination of the raw material - “limestone”, in artisanal ovens at temperatures in the order of 900º / 1000º C. This process lasts for 4-5 consecutive days, so that the calcination of the raw material press is as complete as possible, and that way we have a high purity lime. Upon completion, it is subjected to careful selection processes in order to eliminate residues and other impurities.
