Are tiles made of white clay bodies or bisque superior to those made with red clay bodies?
No. However, to keep color purity when glazing over red clay, an initial layer called an "engobe" is applied. Eliminating this step by using white clay may help keep production costs down.
All tiles are not the same thickness and most handmade tile lines are thicker than inexpensive tile lines. Are inexpensive tiles thin because they use less clay to keep costs down?
No. Inexpensive tiles are thin because they are typically mass produced by a machine that allows the clay to be compressed into a dense but thinner tile.
Are surface glaze irregularities like pin-holes, occasional small specks, glaze build-up, glazed over nicks and chips considered defects in handmade tile?
No. The hand of the ceramic artist is evident in the irregularities and variation that is inherent in a handmade and hand glazed tile and part of their charm.
Can I mix white or off-white glazes from different tile manufacturers or lines on the same installation?
No. NEVER mix white, off-white or neutral glazes from different tile lines. Factories use different bisque and glaze recipes and over the expanse of a wall or floor, they can look very different from one another. Even if the samples look close there is too much variation when installed next to each other and this problem is amplified with hand painted glazes. A sample cannot tell the whole story.
Are thick tile stronger and more durable than thinner tile?
No. The thickness of tile has to do with the method of production and the type of clay body and bisque, not its strength and durability.
