Sand the surface with sandpaper. Rough it up and don't worry about leaving a smooth surface.
Pour a pint of medium in the container.
Add acrylic paint in the color of choice. A light blue-green is a good cool choice. Warmer options are light orange and red oxide. You may also choose to match tiles or window treatments, for example. Add a teaspoon first, then mix.
Test the glaze when fully mixed. It should be almost opaque, with some color from the surface underneath peeking through. If not, add more paint. If it's opaque, add more medium.
Brush on the glaze. Follow the grain or use vertical strokes. Allow it to dry.
Rub into the surface with steel wool. Buff it and scrape up the finish. Work the corners especially hard, as the the edges next. This is where the preponderance of natural wear occurs.
