Marmorino

from Wikipedia, the free encyclopedia

Marmorino , also called Stucco Veneziano, is a mineral lime plaster for lime pressing techniques , especially for the production of stucco marble . It can also be used to create images.

history

Marmorino processes were already known in Roman times, possibly earlier. Examples have been preserved in Pompeii . Technique as an artistic skill was codified by various art schools in Europe during the Renaissance. The Italian school was more abstract, while the French school was more formal and realistic. In general, a 10-year training course had to be completed.

Material in modern times

The Venetian stucco is a manufacturing technique; three layers are applied to a smooth surface with a smoothing trowel .

Marmorino is a mixture of slaked lime and ground marble ; It is sold under different names (selection): Stucco veneto, Calce Rasata, Stucco Veneziano, Grassello di Calce, Stucco Antico, Stucco Lustro , Marmo Antico and Spatula, whereby terms like Stucco lustro actually designate the technology and not the material.

processing

The effect (smooth and shiny) is obtained by puttying two to three layers on lime plaster or marmorino with a Venetian trowel . The drying time is approx. 12 hours for the first layer and approx. 1 to 4 hours for the second layer, depending on the temperature. Then the third layer is filled and pressed with a smoothing trowel.

The fine-grained marble dust in the filler fills the cavities between the coarser grains of lime. Repeated pressing with the smoothing trowel gives the desired gloss and a high level of impermeability.

In the last step and for maintenance, the surface is polished with natural waxes or soaps to protect it from water splashes and to achieve a high gloss.

  • Soap consists of neutral Marseille soap that is dissolved in lime sintered water and boiled. This soap is mixed with vegetable oils as a paste to protect and care for fine and smooth limestone surfaces without distorting the overall appearance.
  • Waxes are used to protect fine and smooth surfaces against dirt and moisture absorption and to increase the gloss. They are made from natural waxes, pure beeswax and Marseille soap.
