When using bowl typologies, we also acknowledge Nol Humes caveat (194) that we suspect remains as valid today as it was 45 years ago: There is, unfortunately, a great deal that we do not yet know about the so-called evolution of bowls and stems, and there is reason to suspect that present stylistic and dating criteria have been oversimplified. For example: Atkinson, David and Adrian Oswald 1980 The Dating and Typology of Clay Pipes Bearing the Royal Arms. Tobacco pipe makers marks appear in a variety of locations on the bowl including on the back, front, and sides, on the base, and on the sides of the spur or heel. Marks were produced by molds that left incuse (negative) or relief (raised) impressions (Oswald 19-91). Because most historical archaeologists can locate a copy of Nol Humes Guide to Artifacts of Colonial America (192, figure 97) within arms reach, this is the most frequently used though admittedly simplified bowl typology. We ask that if you have a nearly complete bowl from which a type can be determined, to use the Oswald 1975 typology, but there is also a field to record reference to another typology, should you prefer. The Archaeology of the Clay Tobacco Pipe, edited by Peter Davey, BAR International Series, 13 volumes 1979-1994. a statistical technique for combining the median age of manufacture for temporally significant pottery types to estimate the average age of a feature or site.assumes that the ceramic types are roughly contemporary at all sites where they occur and the mid-range date of the manufacturing time period approximates the model date of popularityuses tree ring dating to give southwester archaeology a reliable year by year dating tool.Few makers incorporated dates into their marks, though the practice of marking pipes probably initially coincided with the establishment of the London tobacco pipe guild in 1619 and continued into the 19th century (Nol Hume 2003-4).
