The Art of Teaware Care & Longevity
Treat your artisan brewing vessels with mindful reverence to preserve thermal performance, pristine gloss, and generational beauty.
1. Pre-Warm Gently
Always swirl a splash of warm water through ceramic, glass, or cast iron before boiling infusions to prevent thermal shock and prime heat retention.
2. Pure Water Rinse
Cast iron and porous clays should never meet detergent soap. Rinse thoroughly with hot tap water and wipe dry immediately with a clean linen cloth.
3. Breathe & Store
Allow all lids and infusers to air dry completely before placing in storage caddies. Keeps metals shining and prevents trapped moisture.
