painting on dry plaster. Distemper and tempera painting on a dry surface is the most ancient painting technique. Medieval frescoes were often finished with tempera on a dry surface. In medieval Western European art both the secco technique and the fresco technique—painting on moist plaster with pigments mixed with lime-water—developed. Secco was especially popular in Europe in the 17th and 18th centuries. The term “secco” also designates painting on dry plaster with pigments mixed with casein and silicate.
