Chaska brick
From Wikipedia, the free encyclopedia
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.[1]

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 20 to 45 feet (6.1 to 13.7 m) deep.[1]
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.[1]
Third, Chaska was settled by German and Scandinavian immigrants, who came from areas where brick was the favored building material. These immigrants were skilled bricklayers, 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.[1]
