Ceramic cup cover - dust / insulation

Ceramic handmade cup cover Often brewed tea, coffee; poured milk Did not finish drinking for a while Also afraid of dust falling in So I made a simple ceramic cup cover for myself. Only one ~~ unique Dimensions (cm): 11 (diameter) * 0.5 (thickness) cm Material: white pottery / make-up soil, 1230 degree high temperature firing (Glace medicine does not contain lead and bismuth - edible safety) Use and maintenance methods: 1. Before using the pottery, use boiled rice water or put a handful of white rice in a small fire for 30 minutes. After the fire is turned off, let the pottery cool naturally, then rinse with cold water, dry it or dry it naturally. 2. The place where the pottery penetrates into the water is easy to mold. After cleaning, use a rag to dry it and store it. 3. It is recommended to use a sponge to clean and avoid immersing the pottery in the stain for a long time. 4. Microwave / not for use in the oven. Other considerations Handmade, each piece is burned differently, there will be natural glaze, gas spots, each piece of style and color will be slightly different, is also the charm and personality of pottery, can accept the next order.
