Durable temperature porcelain construction provides longterm storage durability and heat resistance for vegetables. Effective fermentation support: pour water around the lid to create a seal that allows gases to escape while keeping the contents secure. Elegant nontoxic ceramic design offers a beautiful appearance combined with foodsafe materials for safe use. Secure sealing performance: the ceramic sealed canister blocks outside air, promotes proper air circulation, reduces oxidation, and helps preserve the quality of pickled foods. Compatibility and uses: ideal for sauerkraut, other cabbage ferments, pickles (cucumbers and similar vegetables), and related fermented storage in a home kitchen. Use scenarios: 1) Fermenting sauerkraut or other vegetables at home by adding water around the lid to form a seal while gases vent. 2) Preparing and storing pickles in a secure ceramic canister to maintain flavor and prevent contamination. 3) Longterm storage of fermented vegetables in the kitchen to preserve freshness and quality. Materials and performance: crafted from temperature porcelain and nontoxic ceramic to ensure safe contact with foods and reliable performance over time.
