TILE - Builders'
Tiles – Builders’ tiles are usually redder in color, come in many different sizes. They are difficult to cut down, not well finished off, have a rough texture and do not fit together evenly. If you have the time to experiment and make trial firings you will find some leave rough, strange textures, which can help certain designs.
If the bisque has a texture full of small holes, you can help eliminate some by wetting the part that is going to be decorated with a large soft brush and clean water. The water blocks the holes so the glaze-base when thrown over it is not affected too much. When fired some are left and this helps to give an antique texture.
