Under this label I include a drawings made with traditional media, such as graphite, charcoal, pastels, crayons, etc., and drawings in which I have experimented with media (traditional or not) with treatment of the surface for achieving desired effects, or to enhance the results of the media utilized to that effect.

Earlier in 2021 I discovered a new product in the art market labelled as liquid charcoal, manufactured by a Canadian firm called Nitram. Out of curiosity I proceeded to buy it and to start experimenting with it with very promising results. Also I decided to test personal versions of a charcoal in a liquid form. The results of drawing with liquid charcoal can be appreciated in the following drawings. Needless to say, I have not concluded yet with the learning process.

Also included within series of liquid charcoal drawings there is a small number of works on paper done with crayons.
