I decided on these cups after looking long and hard for the ideal flared cup for tea appreciation. I knew I wanted something larger than the standard Chaozhou or Taiwanese white porcelain cup, and I wanted it to be as wide as it was tall. These cups were exactly what I wanted, but were so much better than expected once I got them home. I've been using these Dehua porcelain cups for several months and they are my go to cups for serious tea appreciation and evaluation for any tea, although I do use smaller and larger porcelain cups for more casual drinking or for Chaozhou gongfu.
Dehua porcelain is from Fujian, and has been made there since the Ming Dynasty. Here is some information on Dehua porcelain on Wikipedia:
When I purchased two of these cups for my own use earlier this year, I didn't know anything about Dehua porcelain or the history behind it. These cups just seemed to be exactly what I was looking for. This porcelain has been used for tea in Fujian for centuries, of course, and I feel the craftsmanship far exceeds standard Chaozhou and Jingdezhen porcelain. The glaze is really beautiful and the cups feel smooth and soap-like in hand. The tactile sensation of using one of these cups is incredible, and they are flawlessly constructed and perfectly shaped.
These cups are 5.6 cm wide across the top, 4.2 cm deep on the inside and 2.6cm wide at the bottom, and they have a maximum capacity of 50ml. Each cup weighs 29 grams. They are thicker than standard Chaozhou cups, but are still translucent like the finest Jingdezhen porcelain. The porcelain used for these cups is really excellent.
I only have eight of these on hand at this time.
