Opening and caring for an unglazed teapot
紫砂与朱泥壶的开壶、使用与日常养护
Traditional 紫砂與朱泥壺的開壺、使用與日常養護
Care begins with the condition and intended use of the pot. This guide separates routine care of modern brewing vessels from the treatment of historic, repaired or fragile ceramics, then examines cleaning and patina claims.

Before the first brew#
For a new brewing pot, inspect the lid, spout and interior for loose particles, cracks, coatings and repairs before use. Ask the maker how this particular body and finish should be cleaned. This guide does not prescribe simmering every unglazed pot or rinsing every surface with boiling water. Surface cleaning and food-contact verification answer different questions.
Key facts#
Begin with the object, not a ritual: is it a contemporary pot intended for brewing, or an antique, repaired or decorated object? Use the maker’s instructions for everyday ware. A clay name alone does not establish a cleaning method, resistance to temperature changes or food-contact suitability.
Why boiling with tofu, sugar cane, or wax removers is unhelpful#
No evidence reviewed here establishes boiling with tofu, sugar cane or tea as a food-contact test or a way to certify an unknown clay. Such recipes also do not identify a coating or repair. If a pot has unexplained odour or residue, establish its material and intended use with the supplier before choosing a treatment; do not turn an unsupported opening ritual into a guarantee.
Reading a sheen or a dark deposit#
Baojiang is a connoisseurial description of a developed surface appearance, not a chemical diagnosis. A sheen alone does not distinguish use, polishing, coating or dirt. This guide therefore does not attribute every patina to tea oils or every dark deposit to a particular chemical or organism. For everyday brewing ware, remove spent leaves, clean according to its instructions and allow it to dry before storage.
Temperature changes and thin-walled pots#
Firing shrinkage and thermal expansion during use are different properties. A percentage change over a temperature interval is not a thermal-expansion coefficient per degree. No verified sample-specific coefficient or universal prewarming temperature is supplied here. Follow the maker’s temperature limits for brewing ware. Historic or repaired ceramics require conservation advice rather than a kitchen heating procedure.
Further comparison#
Choose the care regime by intended use and condition. For a modern brewing pot: check its instructions, inspect before use, remove leaves afterwards, and dry before storage. Whether a detergent or immersion is suitable depends on its finish and construction; neither “never soap” nor “always boil” is a universal rule. The Canadian Conservation Institute’s guidance concerns preservation: it directs unglazed, unevenly fired or soft historic ceramics to a conservator. That is not a blanket ban on washing modern functional teapots. CCI
