Tiles – broken and cracked.
Tiles must be sounded before decorating to make sure they are not broken or cracked. This can be done when the piece is in the state of dry clay state, either bisque or glaze fired. With bisque sometimes the cracks can be heard but not seen, if so using your hands force them downwards until they separate, The broken parts can be cut down to special sizes for borders, corners, testing colors, making mosaic patterns, supports for the kiln, etc. With tiles that have been glaze fired cracks can be seen as they separate the glaze, this is shown in the two photos.
