We’ve been sellingBeeswax linen covers for pots,jugs and other items for a while now. With the heat of your hand, they can be gently pressed around the container, keeping the inside protected and making it easier for storage and transportation.
Here are the documented resources that I have so far been able to track down which show what I believe to be linen beeswax covers over the jugs. Any other sources that I find or am told about will be added to this list so that future people don’t need to go nuts trying to track down original extant sources for this.
The French National Library has a 14th century copy of Tacuinum Sanitatis which has several images of jugs and pots covered with cloth. Some have string tied, some don’t. Several look like jugs with beeswax cloth.
