After researching all the available objects from the collection of the Koninklijk Zeeuws Genootschap der Wetenschappen on trade routes and origin. I decided to go further with the 'Jakoba Jar' (Jakoba Kan) for a number of reasons I will demonstrate in my research below.

In order to organise all the data acquired during the first phases of the research, we traced it with Chinese ink. During this process, the main elements stand out and new patterns are made.

During my research on the Jakoba Jar, I found a group with a passion for the late medieval times. More specifically, they reenact Dutch medieval lifestyle. They also have a fascination for the Jakoba kan which they make replicas of.

The Jakoba Jar were originally made in Siegburg (Germany) around the 14th and 15th Century. Considering this was Medieval times, these jars were mass-produced and extremely popular even in the Netherlands. Today, they are regularly found in various archeological sites.

According to Christoph Kühne, a PdD student at Göttingen University, Siegburg Stoneware trade was rarely documented; however, it "is one of the most well known indicators of late medieval urban material culture" (Kühne C., April 2014)

Information on Jacoba jars is quite limited as it is a very 'niche' interest. Most sources come from auction-houses that sell medieval stoneware.

The Jakoba jar is considered to be 'stoneware'. Generally, it was used to drink beer or cider. This type of stoneware was made out of impermeable clay found in the region of Siegburg. This is one of the reasons of for its popularity in Zeeland as the clay there wasn't suitable for liquids. The clay is heated up to 1200 degrees turning it into stone. An important feature typical for these jars is that they were not glazed. The reddish blush on my Jakoba jar specifically is due to salt ash in the oven.
