Isolation layer

I got from a friend some very fresh eggs. Very good to make a tempera. As color I choose oker.  I separeted the egg yolk and added a little lavendel essence against mold...  Also I added a spoon of linseed oil.  I mixed this carefully. 

This I mixed with the oker pigment adding a little demineralized water.  Later on I added more of this water. 

In total I did three large canvasses and a small one. Two of them got two layers of tempera. The other two only one.
