Portraits in sanguine
This material is very similar to charcoal, but is red. At the beginning, it was real black, red or white natural stone, which was mainly of Italy.
Different shades of red as well as the differences in hardness are obtained by calcination (the plot is more or less smooth and precise depending on the hardness of the mine).
Although they fade harder than charcoal. I draw portraits in red chalk pencil and pastels on watercolor paper. So that the sanguine takes good on paper I use a fixative. When the portrait is ready, you will have to frame it yourself according to your taste and your home. Its very important to store the painting longer and protect it from moisture. '
