Chaska brick is a distinctive brick known for its unique cream color, high clay content, and quality, originating in Chaska, Minnesota, United States. The Chaska brick industry flourished from 1857 until 1950. First called "Chaska brick" in an 1894 Chaska Herald article, this product remains closely tied to the history of the city from which it came. Background Three key factors led to the success and popularity of Chaska brick. First, the brick is made from clay found in deep, rich, alluvial clay deposits, with a distinctive layer of yellow clay over blue. Both clays are rich in sand and finely ground silica, giving the bricks a slight sparkle. Early use of wood to fire the brick versus later gas oven firing also caused sparkling. Early brick makers in the 19th century thought the deposit to be limitless, but it turned out to be about deep. The existence of nearby rich wood sources to heat the brick-making kilns was another reason for the Chaska brick industry's success. Chaska and Carver County are located in what was once the Big Woods of western Wisconsin and south-central Minnesota. This large forest of oak, maple, basswood, elm, ash and white birch provided tons of wood to heat the kilns. Many farmers clearing land traded firewood for brick, and off-season brick workers cut firewood for their employers. Third, Chaska was settled by German and Scandinavian immigrants, who came from areas where brick was the favored building material. These immigrants were skilled brickmasons, and provided experienced labor for the brickyards. Chaska brick also weighed less than other brick, making it cheaper to transport. Brick making and firing techniques improved over time as well. History By the 1860s, four main brickyards existed in Chaska, employing about 100 people overall, in a town of only 1,255 people. By the 1880s, the number of employees had risen to nearly 400. By 1900, daily production reached a prodigious three and a half million bricks. Six brickyards employed around 600 men, 20% of the city population, making Chaska brick the leading source of jobs and money for the town. By the beginning of the 20th century, 30% of all brick used in Minnesota was made in Chaska. Many important buildings in Minnesota are constructed of Chaska brick. For example, in Minneapolis, it can be seen in the Orpheum Theatre, Renaissance Square, International Market Square, Wesbrook Hall on the University of
