Drawing and experimenting with egg tempera

From time to time I come across paintings online that are done with egg tempera.  I have read about how to go about making it, but I have never tried it until now.  Following instructions online,  I used tubed gouache paint in place of powdered pigment,  and the egg yolk and water mixture to create the egg tempera paint.  I really liked the velvety smoothness of the paint, and love the feel of it as I painted it on.  The paper I used is a cream colored Stonehenge paper.  I think I would like this manner of painting, as it is not painting in broad strokes or pushing paint around... it is more linear, like drawing, swiftly making lines with it, cross hatching or scumbling... it dries very quickly, and then it's ready for another layer.  As I read about it more, I see that it would take much practice, and patience, but the luminous quality of the paint makes it appealing to do.  The only drawback would be mixing fresh egg medium, and mixing the paint each painting session.  It dries on the palette quickly too... But it is so much prettier than the mat gouache paint.
