Encaustic paint is great for creating texture -that was one of the reasons I was first drawn to it. As it is a solid paint that becomes liquid by heating, temperature is the key. At cooler temperatures the paint will have a paste like consistency. By layering this thicker paint, a technique called accretion*, various textures can be created. Working subtractively on a painting with a warm surface can also create textures that would be recessed instead of raised. Adding collage elements or casting shapes with impasto medium are other choices for adding texture. Several detail images from my paintings illustrate different textures. In one the actual honey comb was incorporated into the painting's surface.
