Short answer: Do not use antique, excavated, or unknown-origin Tenmoku or Jianzhan bowls for drinking tea. Do not use 84 disinfectant, bleach, or strong disinfectants to prepare drinkware. Use modern food-contact teaware for drinking, and keep old or uncertain pieces for display unless a qualified ceramics conservator or relevant testing process confirms they are safe.
Why old Tenmoku and Jianzhan pieces should be treated carefully
Old ceramics can carry unknown residues, repairs, soil contamination, glaze damage, or material risks that are not visible from photos. Boiling, bleaching, or repeated rinsing cannot prove that an antique or excavated bowl is safe for drinking tea.
What not to use on tea drinkware
- Do not use 84 disinfectant, bleach, or strong household disinfectants on pieces intended for tea drinking.
- Do not boil old or unknown-origin ceramics to make them "safe" for use.
- Do not use abrasive powders, metal scrubbers, or harsh chemical cleaners on glazed teaware.
- Do not drink from pieces found in water, soil, tombs, kiln sites, or other uncertain environments.
How to clean modern Jianzhan Tenmoku teaware
For modern teaware sold for daily use, rinse with warm water after tea, use a soft sponge, and add a small amount of mild dish soap only when needed. Rinse thoroughly, dry fully, and avoid sudden temperature shock, dishwashers, bleach, and abrasive cleaners.
What to do with antique or unknown-origin pieces
If a piece is old, excavated, repaired, or from an unknown source, treat it as a display or study object. If you want to use it with food or drink, consult a qualified ceramics conservator or arrange appropriate food-contact safety evaluation before use.

Can I drink from antique Tenmoku or Jianzhan bowls?
Do not assume antique or unknown-origin bowls are safe for drinking. Use them for display unless their condition, repair history, and food-contact safety have been professionally assessed.
Can I use 84 disinfectant or bleach on tea cups?
No. Strong disinfectants and bleach should not be recommended as a way to prepare old or unknown ceramics for drinking tea. They can create safety, odor, residue, and surface-damage concerns.
