Cobblestone Beach was a limestone quarry. Cobb's Lake
was formed by taking limestone blocks from this quarry. Many the atmosphere in the kiln. For example, pink colored bricks are the result of high iron content, white or yellow bricks have higher lime content. Most bricks burn to various red hues, if the temperature is increased the color moves through dark red, purple and then to brown or grey at around 1,300 C (2,372 F). Calcium silicate bricks have a wider range of shades and colors, depending on the colorants used. The names of bricks may reflect their origin and color, such as London Red and Cambridgeshire White. |
