From Lynch (2009): “From initial observation, the tan color 24 seems to indicate that the clay came from Lake Pontchartrain. The sample also has iron spots on the surface. The brick does not have a brickmaker’s stamp, although it is likely that the brick dates to the 1910s. This sample is regular in shape, has sharp-pressed edges, and is struck from header to header across the bedding face. The strike marks on the brick indicate that it was struck with a metal striker, which is consistent with the period. The lack of sand in the surface indicates that water was used as a molding lubricant. Given these characteristics, the brick appears to have been produced through extrusion using the stiff mud method”
From Lynch (2009): “From initial observation, the tan color seems to indicate that the clay came from Lake Pontchartrain. The sample also has iron spots on the surface that possibly could have been added in the mix during production. The brick does not have a brickmaker’s stamp, although it is likely that the brick dates to the 1830s. This sample is regular in shape and has sharp edges, although the striking direction is unclear. The strike marks on the brick indicate that it was struck with a metal striker, which is consistent with the period. The presence of sand in the surface indicates that sand was used as a molding lubricant. Given these characteristics, the brick appears to have been moulded using a soft-mud machine.”

From Lynch (2009): “s. From initial observation, the tan color seems to indicate that the clay came from Lake Pontchartrain. The sample also has iron spots on the surface. The brick does not have a brickmaker’s stamp, and the date is unknown. This sample is a regular brick, has sharp edges, and is struck from header to header across the bedding face. The strike marks on the brick indicate that it was struck with a wooden striker, which is consistent with the period. The lack of sand in the surface indicates that water was used as a molding lubricant. Given these characteristics, the brick appears to have been made using the stiff-mud method and subsequently repressed.”
