The period at the turn of the 4th and 5th centuries produced a wealth of pottery, including large storage jars with a T-shaped rim and decorated with single or multiple wavy lines and horizontal grooves on the rim and body. It is a fairly specific pottery form that is quite rare at Slovenian sites; apart from Rifnik, a more substantial quantity has only been excavated in Kranj. Elsewhere (Hungary, Bulgaria, Croatia, Serbia), such jars are known in greater numbers on a few sites only and are similar to those from Rifnik in shape and decoration, but not fabric. At Rifnik, their fabric is the same as that used for several other kinds of pottery from the same period, which suggests a local production that followed the general trends of the day.
