§ 30 Stucco Made With Marble Dust
Now let us show how the stucco is mixed.133 Chips of marble are pounded in a stone mortar; no other lime is used for this stucco save white lime made either of marble chips or of travertine; instead of sand the pounded marble is taken and is sifted finely and kneaded with the lime, in the proportion of two thirds lime to one third pounded marble. The stucco is made coarser or finer, according as one wishes to work coarsely or finely. Enough now of stuccoes because the rest will be said later, when I shall treat of them in connection with Sculpture. Before passing to this subject, we shall speak briefly of fountains which are made for walls and of their various ornaments.
