(or a secco
) is a fresco painting
technique in which watercolors
are applied to dry plaster
that has been moistened to simulate fresh plaster. In true fresco (buon fresco
), the plaster is still fresh and has not dried when the watercolors are introduced.
Because the pigments do not become part of the wall, as in buon fresco, fresco-secco paintings are less durable. The colors may flake off the painting as time goes by. But it has the advantage of being able to work indefinitely longer time or make aftertouch.
