Acrylic Wash Glazing

I learned the acrylic wash glazing process from a  course taught by the late Marie Gibbons. It was taught through the "Teachin' Art" on-line series. I start with acrylic paints that have been diluted with water. My first layer is a dark color to saturate my bisque fired clay. When it is dry I wipe it off, leaving the darkness mainly in the cracks and crevices of the clay. I then add the colored washes, keeping them very diluted. If more color is desired I add further layers of the diluted paint. I do not darken the washes themselves because that makes it look like acrylic 'painted' clay.
