A conventional brick is made of clay or shale that is formed, dried, and fired into a durable ceramic product. There are three ways to form the shape and size of a brick: extruded (stiff mud), molded (soft mud), and dry-pressed. Most bricks are made by the extrusion method.
A brick achieves its color through the minerals in the fired clay or through coatings that are applied before or after the firing process. This provides a durable color that never fades or diminishes.
HOFMANN’s Renewable Green Brick substitutes clay or shale with recycled stone in the form of a dried stone sludge. Stone sludge is created by wire cutting or sawing granite, limestone and sandstone blocks. The sludge is collected in large settlement basins at Hofmann's factories.
This 100% natural by-product of Hofmann stone processing operations is dug out after drying and shipped to a local manufacturing plant kiln that molds and fires the brick.
A wide variety of colors and textures are possible. Hofmann's specialty handmade brick product pleases highest architectural standards and expectations for a bespoke and customized look.
The Renewable Green Brick is able to make a great contribution to any project’s decarbonization effort as the use of stone sludge instead of clay/shale reduces the product’s carbon footprint significantly.
