For those researchers working in the field of human history, the chronology of events remains a major element of reflection. Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.
There are two main categories of dating methods in archaeology : indirect or relative dating and absolute dating. Relative dating includes methods that rely on the analysis of comparative data or the context eg, geological, regional, cultural in which the object one wishes to date is found.
The diameter of the hole in the pipe stem generally indicates the date the pipe was made. Archaeologists often use drill bits to measure the.
Pipe stems and bowls such as these are very common among finds at digs in the northeastern United States, given how common they were during the 17th, 18th, 19th, and early 20th centuries. They were made of kaolin, a type of clay that was pressed into a mold and sometimes stamped or decorated before being fired in a kiln.
The smoker would periodically break off pieces of the pipe stem as they wore down and eventually discard the whole pipe, including the bowl. They were a disposable item. The relative size and shape of a pipe bowl or stem is also often an indicator of its age; earlier pipe bowls are smaller, and newer ones are larger. The diameter of the hole in the pipe stem generally indicates the date the pipe was made.
Archaeologists often use drill bits to measure the diameter of pipe stem holes. In general, the wider the stem hole, the older the pipe. Based on the diagnostic information they show, my goal is to figure out the meanings and contexts behind the words and symbols stamped into the pipes, and to measure the diameters of the stems for a more definitive date of manufacture.

Archeology and dating go hand-in-hand. Historical archeologists have an advantage when it comes to dating because of the written historical record. When we study a site, we also study the documents associated with the site. For Historical archeologists, ceramics are a diagnostic tool for dating because many English ceramic types can be dated to within 5 or so years of their manufacture.
Examples of relative dating are Dendrochronology and palynology. Archaeological Site. Location of a Site. Finding a location is.
All rights reserved. Relative techniques were developed earlier in the history of archaeology as a profession and are considered less trustworthy than absolute ones. There are several different methods. In stratigraphy , archaeologists assume that sites undergo stratification over time, leaving older layers beneath newer ones. Archaeologists use that assumption, called the law of superposition, to help determine a relative chronology for the site itself.
Then, they use contextual clues and absolute dating techniques to help point to the age of the artifacts found in each layer. Learn how archaeologists dated the earliest metal body part in Europe. Objects can be grouped based on style or frequency to help determine a chronological sequence. Relative dating has its limits. For a more precise date, archaeologists turn to a growing arsenal of absolute dating techniques. Perhaps the most famous absolute dating technique, radiocarbon dating was developed during the s and relies on chemistry to determine the ages of objects.
Its inventor, Willard Libby, eventually won a Nobel Prize for his discovery.

Archaeologists accomplish heir task mainly through excavation. Excavation is the process of finding sites that may contain artifacts. Artifacts are relics of the past. They are anything created or influenced by man.
Therefore, attaining information requires archaeological research. Historic evidence on Artifacts as Time Markers: Pipe Stem Dating. US Department of.
Archeological testing was undertaken, at the site of Fort Argyle 9Bry28 , one of the earliest frontier forts constructed in Georgia The primary goal of the project was to confirm the site’s location through archeological and historical methods. Traditional prospecting methods were used in conjunction with electronic remote sensing techniques, excavation of test pits to locate structural remains, and underwater archeological survey.
The palisade encompassed an area measuring 33 m ft square. An examination of artifact class ratios shows that the assemblage falls within the predicted range for frontier military sites. Ceramic analysis indicates that the mean date of occupation was , but a date of was obtained through pipe stem dating techniques. Historic documentation indicates that Fort Argyle was occupied sporadically and was renovated on several occasions. The last reference to any fortifications at the site dates to Excavations show the site to be in an excellent state of preservation and there has been little post-colonial period contamination.

A total of 56 clay tobacco pipe fragments were recovered from the C site. Among these 56 fragments, eight stem to bowl junctures or complete bowls 2 of which bore makers marks , eight bowl fragments, 37 stem fragments with measurable bores and three unmeasurable stem fragments were recovered. The pipe stem fragments were distributed by bore diameter in the following manner:.

Abstract: There are currently three formula dating techniques available to archaeologists studying 17th and 18th century sites using imported English clay tobacco pipe stems based on Harrington’s histogram of time periods; Binford’s linear formula Hanson’s formulas and the Heighton and Deagan formula. Pipe stem bore diameter data were collected from 26 sites in Maryland Virginia North Carolina and South Carolina in order to test the accuracy and utility of the three formula dating methods.
Of the formulas the Heighton and Deagan proved to be the most accurate producing formula mean dates closest to the dates assigned to the sites using other dating techniques. It was also determined that all three formula dating methods work better in Maryland and Virginia than in North and South Carolina.

The site also contains a Late Woodland period lithic scatter. Phase II included additional surface collecting, shovel testing at 25′ intervals, and one 4’x3′ excavation unit. Phase III data recovery excavations consisted of extensive mechanical stripping to expose features. Cultural features identified included six original postholes and six replacement postholes and associated molds, representing the footprint of an earthfast building measuring 20′ by That the building was a dwelling seemed evident by the large root cellar at one end, filled with burned daub and charcoal.
In addition, eight borrow pits were identified to the south of the building, most of which cross-cut one another in a manner typical of early Colonial sites. The various lines of evidence–archival, spatial, stratigraphic, and artifactual–admit a fairly straightforward interpretation. The dwelling, on land occupied by Native Americans sometime in the Late Woodland period, if not earlier, was built in the last decade of the 17th century by Bernard Johnson for himself or by and for tenants.
The pipestem dates, the scarcity of white salt-glazed stoneware sherds, and the relative abundance of Rhenish blue and gray and English brown salt-glazed stoneware sherds support that initial date. Sometime in the early part of the second decade of the 18th century, possibly with the conveyance of this parcel to William Wilkerson, a tenant household rehabilitated the dwelling, replacing the original posts and reconstructing the wattle-and-daub chimney.
While some of their trash may have ended up in the original borrow pit Feature 1 , the tenants probably deposited most of their kitchen refuse, and some architectural debris, into their principal borrow pit Feature Precisely when the site was abandoned remains uncertain.
