The Conté Colour carré crayons give accurate and energetic strokes when the edges of the sticks are used, and artists can produce flat areas by using the flat of the crayon to create the values. These crayons are very soft to use and are manufactured using natural pigments (iron oxides, carbon black, titanium dioxide), clay (kaolin) and a binder (cellulose ether). They are then baked after being extruded and dried. The degree of baking varies the grade (hardness: H/softness: B) of the black and white crayons. Two special tints for portraits (rose and brown) were recently developed and enhance this “sketching” range, a genuine artistic reference for all Artists. The Conté crayons can be used in different ways: Using the “flat edge” of the pastel by varying the pressure (the greater the pressure on the pastel, the denser will be the colour obtained); Holding the carre upright or slightly slanted, you can draw using the 8 angles at the end of the pastel (allowing you to sketch and structure the drawing)
