Good Evening,
Please go here:
http://www.italianfrescoes.com/sistinechapel.aspMichelangelo Buonarotti would have had a tough time sketching out the
entire ceiling of the Sistine Chapel since he did not paint ON the plaster
but more accurately IN the plaster. Frescos last so long and are so
durable because the artist works his painting into the surface of fresh
plaster. The pigment and the plaster bond together so the pigment is held
within the outermost layers of the plaster. The artist can only paint a
limited amount of area before he (or she) has to stop because the plaster
has set up. Each session must start with mixing a new batch of plaster,
wetting the area to be covered with plaster, apply the plaster, and then
paint. This does not count the time taken to grind the pigment and mix
the linseed or poppy seed oil with the pigment. Frescos take time because
of all the preparation involved as well as the actual painting time.
There may have been assistants to wet the walls, grind the pigment, and
lay on the plaster but as far as I have read the actual painting was done
by Michelangelo between 1508 and 1512.
