About this piece:
A used cup with showing cracking glaze web coloured already, some cups gets these webs pretty fast some only later. Even the inside of the cup looks like used for ages I tried only several times. It has already this feel of being used for years.

First 6 pictures show aged/used Jiri Duchek cups. When you get a new teapot/cup/picher it is very interesting to observe from a session to a session such changes taking place.

The cup is made by naturally and locally sourced clay by Jiri Duchek itself. It also contains a bit of locally sourced kaolin clay which is used for porcelain making. Additionally is glazed with a thin layer of white glaze. Such glaze is used in old times in Korea. You may check an aged cup from Korea on the following link.

Tea drunk from such a cup has round, mild and pleasant taste, similar taste as achieved by pure porcelain cups. This type of glaze makes tea taste more neutral, clean and pleasant. It kinds of purifies the final taste of tea.

The glazed fired shred will slowly age and change its color. A web of black cracks will appear and change the look of a cup. This web of cracks is unpredictable and could differ from a cup to a cup. Also the time when they appear is not fixed.

Each cup has an unique shape, size, fire marks. The cup surface is very smooth and nice to touch. The inside of the cup is glazed too and cracks will appear too.
