Abstract: A color wheel having a plurality of pieces is disclosed. Selected brick pieces may be stacked upon each other side-by-side and a viewing apparatus laid upon the stacked brick pieces. The viewing apparatus may have a viewing window which can be adjusted in order to adjust the percentage of each of the brick pieces being viewed through the viewing window of the viewing apparatus to provide for a more accurate perception of how the selected colored pieces will be perceived when implemented in a brick building.

Abstract: A method and apparatus for making ceramic articles, particularly adapted for making roofing tile of S-shaped cross section, wherein a clay extrusion of essentially hollow triangular shape form three sets of tile having severable connections along the apices of the triangular extrusion, each set being S-shaped and supported, as extruded, by a core of corresponding shape; the axial movement of the extrusion being stopped intermittently while serrated blades conforming to the core are pressed radially against the core to score the extrusion and form severable connections dividing each set of tile; the extrusion being severed at selected transverse planes to produce a multiple tile unit for kiln heatment, the tile unit including integral but severable end portions forming kiln furniture for supporting the multiple tile units.
