Care for Jian Zhan by rinsing it soon after tea, washing with a soft sponge and mild unscented soap, avoiding sudden temperature changes, and drying it completely. Jian Zhan is functional high-fired stoneware, but a careful routine protects the rim, glaze, and appearance for years of regular use.
Before the first use
Inspect the cup in good light and rinse it with warm water. Wash it gently with a soft sponge and a small amount of mild, fragrance-free dish soap. Rinse thoroughly. There is no need to boil the cup, season it with tea, or use abrasive powders.
After every tea session
- Empty the cup while the remaining tea is still fresh.
- Rinse with warm water so pigments do not dry on the surface.
- Use a soft sponge when needed; avoid steel wool and abrasive pads.
- Rinse away all soap.
- Dry with a clean cloth, then allow air circulation before storage.
This routine is especially useful after dark tea, matcha, coffee, or any drink that can leave visible residue. A mineral glaze can be dramatic without needing a layer of accumulated stain.
Avoid thermal shock
Ceramic objects can crack when temperature changes too quickly. Do not take a cold cup from a refrigerator and immediately fill it with boiling water. Do not pour cold water into a very hot cup. Pre-warm with warm water, then add hotter water gradually. Place the cup on a dry, stable surface rather than a very cold countertop.
What about tea stains?
For light staining, soak briefly in warm water with mild dish soap, then wipe with a soft sponge. Repeat patiently instead of scrubbing aggressively. Avoid bleach, harsh chemical cleaners, and abrasive powders unless the maker specifically approves them. The goal is to remove residue without dulling the glaze or marking an unglazed foot.
Dishwasher and microwave guidance
Hand washing is the safest default because it protects the rim from contact with other dishes and avoids aggressive detergents. Microwave suitability depends on the specific clay, glaze, and any metallic visual effect; Mo Lan does not recommend microwave use. Do not use Jian Zhan on a stovetop, in an oven, or over direct flame.
How to store a collection
Give each cup enough room that rims and glazed walls do not knock together. If stacking is unavoidable, place a soft, clean separator between pieces and keep the stack low. Avoid damp closed cabinets. Pick up a cup by supporting the body rather than pinching a thin edge.
A compact form such as Frost Pine and a wide bowl such as Cloudburst Well need different shelf space, so check dimensions before planning storage.
Using Jian Zhan beyond Chinese tea
Jian Zhan can be used for oolong, black tea, green tea, white tea, matcha, and small servings of coffee. Strongly flavored drinks will not permanently redefine the cup if it is cleaned promptly. If you prefer a purist tasting practice, dedicate one cup to a family of teas; if you prefer daily ease, use it broadly and wash it well.
Frequently asked questions
Do I need to season Jian Zhan?
No. A clean cup is ready to use. Any gradual visual change should come from normal use, not forced staining.
Can I leave tea in it overnight?
It is better to empty and rinse the cup after use. This prevents stubborn residue and odors.
What if I notice a crack?
Stop using the cup for hot liquids. Photograph the area in clear light. If it arrived damaged, contact gerrelierus@gmail.com within three calendar days of delivery.
