Hi! I would be most grateful if anyone could answer some questions that have been bothering me, particularly regarding the strappo technique. Regarding large frescoes and sinopias in museums such as the ones in Pisa you mentioned and the ones in Mantua by Pisanello, how have they managed to separate the sinopia layer from the fresco layer which has been painted on top? Is it using the technique you describe? Also, when you sketch a sinopia how do you actually use it, if you are going to plaster over it when doing the fresco? How is it possible to see the original sinopia design when you are painting, if there is a fresh plaster layer on top of it? And finally, I recently saw some frescoes in a church covered in "scars" where bits of the plaster had been very deliberately hacked off. Not all the frescoes in the church were damaged like that, but I wondered what the reason behind it was. SOmebody said that they covered the church in lime when it was used as a hospital and needed to hack through the fresco so the lime wash would adhere to the wall, but this didn't explain why all the frescoes were not damaged in such a way. Thanks a million for any advice!
