Ceramic gaiwan porcelain teacup
- Avoid extreme temperatures. Don’t freeze porcelain. Keep it out of the oven and away from direct flame.
- Go easy. Use mild soaps and detergents. High-strength detergents in your dishwasher are overkill for porcelain. Never use abrasive cleansers.
- Clean up fast. Empty and rinse your porcelain mugs right away.
- Gray and red. Gray marks on porcelain are caused by metal utensils leaving deposits of nickel on the surface.
