Back then, most pottery was created to be used in everyday life by an individual that probably lived near you.
The makers rarely marked these pieces because beyond there usefulness, the items weren't much to look at.
Beginning in 1901, the company stopped adding flames to the logo and started using roman numerals below the fourteen flame trademark to date the pottery.
In 1906 Van Briggle Pottery stopped using Roman numeral markings and for the first time added either Colorado Springs or Colo Springs to the bottom marks.
Early 1907 Van Briggle Pottery often has marks that include the logo, Van Briggle, Colo Spgs, shape number, and date.
With a basic knowledge of clay color and texture and bottom markings, approximate dating of Van Briggle Pottery can easily be determined.
Since the majority of collectors are interested in dating early examples of Van Briggle this discussion will focus on dating examples from the 1920s and earlier.
