For my extruder project, I decided to just put a solid glaze on it. I didn't want to decorate it any more than what I already had. I made holes in the rectangular pieces, and I didn't think that I needed to add anything else. The color of glaze that I choose was green. I had to apply three layers of this 'green' colored glaze. Although the glaze is green, after firing it turns out to be a gray, metallic color. It made my piece look really antique, and I really like the way that it looks.
