EAGLE POINT LIME WORKS
EAGLE POINT LIME WORKS. North-end business of the early 1900s. Started in 1890 by George FENGLER, the lime works were located below the bluff at EAGLE POINT and had a peak production of 250 barrels daily. Lime was produced by heating limestone to temperatures up to 1300° C. This heating process, called calcination, resulted in the production of lime, or calcium oxide (CaO), and carbon dioxide (CO2). In the nineteenth and early twentieth centuries, lime was used mostly in construction for making mortar, plaster, and whitewash. It also was used for tanning hides, agricultural applications, and sanitation.
The fact that it was sold in Michigan, where it was used in the iron factories, was said to prove the superiority of the Dubuque product. In addition to lime, the Eagle Point Limeworks carried a full line of fire brick, building brick, plastering hair, cement, and stucco. The rock quarry, later the property of Dubuque Stone Products, eventually became Eagle Point Fun Land.
The 1916-1917 White's Dubuque County Directory and 1918 Dubuque City Directory listed Lime near Lincoln Avenue as the address.
