It is the most traditional painting material. It consists of applying oil-based paints to cotton surfaces or other materials. Normally brush and spatula are used for application. It allows for a good finish and flexibility due to the slow drying of the paint. Normally oil paint takes a long time to dry, which means I can change the work and make some corrections if they are necessary.
For a better conservation of paintings with this technique, I advise against touching the painted surface, do not hang it in a place where the sunrays directly affects the screen (because it can change the color tint and cause cracking of the surface) and clean the painting with a dry soft cloth.
