The clays used are often described as being long or short, depending on their plasticity.Long clays are cohesive (sticky) and have high plasticity; short clays are less cohesive and have lower plasticity.These principles allow extension of the methods to prehistoric cases in some circumstances.The formulas, however, produce single numbers that may be misleading in their apparent precision.The English had read the letters of Jesuit missionary François Xavier d'Entrecolles, which described Chinese porcelain manufacturing secrets in detail.

The results suggest that archaeologists should report these dates with their standard deviations and not as single-number results.The word paste is an old term for both the unfired and fired materials.A more common terminology for the unfired material is "body"; for example, when buying materials a potter might order an amount of porcelain body from a vendor.Since the advent of pipe stem-bore diameter and mean ceramic date formulas in the 1960s and 1970s, formula dating has been a widely accepted technique for the accurate estimation of median occupation dates of historical sites.The methods are based on fundamental concepts of archaeological analysis: horizon, tradition, and testing by repeated application.
