Conté and Chalk Drawings

In the pictures below chalk an conté are the materials being used. 

In this drawing conté and chalk are the friable materials being used. The darker spots, low lights, are done by conté. The lighter spots, highlights, are made with chalk. 

In this drawing the conté being used is brown. In class we are using black conté. This drawing is alike to the previous, but with the difference of the highlights. The difference is that there are not as many highlights. 

In this drawing the material used was chalk. There is a difference between chalk drawings and conté drawings. The difference is you can't work highlights and/or very many low lights into the drawing.

Out of the outcome from these three drawings I think that the best material for drawing out of conté and chalk is conté.
