Since 1920 La Calce del Brenta produces lime-paste and colour marble powder to create antique lime-based finishes like stuccos, marmorino, glazing finishes, lime based paint. The lime putty is still obtained in the heart of an antique tub shape furnace with natural wood-burning fire utilising ancient working methods. Vivaldi Armonie di Colore is a colorimetric system created for the decoration of interiors and exteriors. Thanks to the addition of twelve Vivaldi Essenze di Colore (Colour Essence) is it possible to obtain infinite shades of colours with the various aesthetics effects proposed by La Calce del Brenta.
