Since the appearance of human beings' interest in expressing their feelings and emotions through art, there has always been a constant search for new materials, tools and procedures on the part of the artist in order to carry out his work as a creator. Throughout the twentieth century, we have had the opportunity to see how techniques as common in painting as the famous oil, acrylic or gouache, and in drawing such as charcoal, pastel or graphite, among many others, have been consolidated. But in 1937, especially by Wolfgang Paalen, a rare pictorial procedure never seen before in the history of art was discovered, called Fumage, a technique based on the black staining produced by the soot from the smoke of a flame on any surface. I have focused this work on it, through my own work and the research carried out over the last two years through pure experimentation.
