The "Don Valley Pressed Brick Company" produced bricks using three techniques. The first was called a soft-mud process. Clay quarried from the site was mixed with water from nearby Mud Creek, placed in moulds which were dried and then baked in kilns. A second technique called dry-press bricks used quarried shale. The shale was placed into moulds and machine pressed. A third process called stiff-mud used a mixture of clay and shale that used less water than the soft-mud process. A column of clay was forced through a die which was then cut to form using a wire. Finished product was shipped by cart out of the valley along Pottery Road or by rail on a spur built into the yard. Bricks were used mostly in Toronto but were used across the continent. The bricks made were of such good quality that they won prizes at the Chicago World's Fair in 1893 and the Toronto Industrial Fair in 1894.
