Theresa Cheek wrote a fine article entitled "Scagliola and Pietre Dure" for her blog "Art's The Answer!" Stuckmarmor is one of many Spachteltechniken and so is Scagliola.
Marble columns made with Stucco technique.
More commonly known Spachtel (trowel) techniques are Tadelakt and Fresco, shown above. Frattazatto, Marmorino, Stucco-lustro, Rasata, Calcerasata, Stucco Veneziano, Stucco Rasante, Spatolato Veneziano, all fit into the lime based trowel techniques.
Large masses of colored stucco is applied onto a base. Smaller veins of conglomerates (cubes) are troweled onto and in-between applied stucco panels.
High spots are removed with special blade. Open areas are filled with stucco slurry. Numerous polishing procedures from rough to the very fine. Then a last coat of poppy seed oil and wax.
All photographs are taken from the book by Martin Benad entitled "Das 1x1 der Spachteltechniken".
