Glazing to me means the material that is used to cover the pastel in it's frame, i.e. , glass. I assume you mean using a varnish fixative to stabilize the pastel surface?
It is not possible to fix pastels so that the particles are perfectly stabilized without dulling or darkening the beautiful colors. Therefore,there will always be the possibility of erosion with vibration etc. Static electric charge on the glass will attract loose pastel dust, especially if he pastel painting is jarred or vibrated and loosen the pastel particles. To avoid this or reduce the effect: pastels should never be framed with the glass touching or too close to the surface of the painting.
I like to allow at least 1/2 inch or even more if practicable. The static charge is not constant. It will vary with environmental and mechanical conditions.
According to Coulombs Law the force of attraction of a given static charge varies inversely with the square of the distance of separation. That is to say for a given ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
