The approximate manufacture date of a kaolin clay pipestem fragment ("A" in the image) can be determined by measuring the inner diameter. In this case, that diameter (5/64 of an inch) suggests a manufacture date of between 1720 and 1750 ("B" in the image).

Kaolin is a type of clay used for making disposable pipes from the early 17th century thru the late 19th century. Its use was widespread, and age can be determined from several factors, including bowl design and pipestem diameters. The latter was developed by J. C. Harrigton.
