In 1997 a friend mentioned to me that they had seen some work by a Mexican artist who was using chapapote in his work. That interested me right away, as I had been experimenting with chapapote at our house in San Miguel de Allende. Painters use chapapote on tile floors. The mixture is different, from one installer to another. As chapapote is tar, yes tar. The mixture I developed was as follows: tar pieces, melted in a large tin can using a hot plate. To dissolve the tar you use white gas. You add some wax, and some paint color, like vermilion. Now the exact amount, of any one of these ingredients, is a Mexican secret concoction. It produces outstanding images.
