Abstract
A process for using an illuminating box for facilitating the level installation of tiles. The illuminating box has a top and four sides which are opaque. The bottom is light transmitting and lies in a single plane so that when a portion of the bottom is placed on one tile and the box is allowed to overhang an adjacent tile, light will escape on any area which lies below the bottom plane of the illuminating box. The process includes the steps of laying at least two tiles on a substrate and turning on the light in the illuminating box. Next, the box is placed on one tile so that its bottom edges extend over an adjacent tile. Next, the resulting light pattern on top of the floor tiles is observed to illuminate any lack of flatness.
