<p>Apparatuses and processes for coating concrete bricks with exposed surfaces having sharply delineated portions of contrasting color and/or texture by periodically and regularly forming atomized particles of a viscous cementitious slurry and directing same on to portions of surfaces of each of a plurality of green concrete bricks in groups located stationary in regular fashion for a brief period and thereafter firing the thus coated uncured brick. The apparatuses include means for rapidly and/or sequestially varying the colors applied to the different groups of bricks during successive cycles of coating the successively treated different groups of such brick.</p> |
