Cups such as this Maigelbecher replica were made from the end of the 14th century onwards. They have a typical relief pattern on the wall. This one is the more common version, but octagonal pieces are also known.
This candle holder is a reference to the bossed beaker. These are glass beakers that occur in late 16th-century or 17th-century archaeological contexts. The wall of the bossed beaker is decorated with a relief pattern in the form of drops, tears, diamonds, warts or … bosses. Just like with this candle holder.
