[Class 87 (i)] Border tiles for covering walls, including corners or recesses, have a marginal strip b bent backwards or forwards through considerably less than a right angle. The backward bend shown is used for an upper row of tiles or a corner covering, the side face c being at an acute angle with the face to allow the glazed edges to be adjacent on a right angled corner. For a base row of tiles or a recess the opposite side of the tile is glazed and the angle of the face c is reversed.
