Thanks to all
Karin, I did not describe the technique very well but it seems that this technique was one of the Old Masters--the artist who does this technique is at
http://flemishrealism.com and his name is David Weaver. I think that is his page. As a matter of fact, I just noticed that on the inside cover of The Artists Magazine June 2002, he is there and Maimeri Paints seem to be endorsing him and his work. Check it out and get back to me.
He teaches with and onion and linseed combination. I am certainly not an Art Historian so I do not know, but it seems that years back this was a common practice for the Old Masters, the onion changing the viscosity of the linseed. I love it not only because of slower drying but because you are actually painting onto wet linseed oil which has been applied to the panel or canvas. I actually rub the oil onto the panel with the palm of my hand. Painting into this is so smooth and pleasing.
And Joan, I know what you mean. I understand that paint dries at different intervals and at the end of all the drying process, I then look at it from the side with the light across it and there is shiny and dull areas, probably showing that I worked on it at different times and it dries at different levels. I hate this too and can't seem to get a smooth all over even look in my finished paintings. There is so much to learn about all of this. I have painted many years and yet when it comes to the technical part of mixing this and that, I do get so confused and quite discouraged.
If anyone there would give a run down of their techniques...just what you use as a painting medium while painting and then what do you put on your finished painting?
