Antiscald Covers / Tableware

The patterns on the covers originate from Chinese blue porcelain and the materials of the covers can expand when heated. Most of the time,he patterns can decoratively keep smooth with the surface of the covers.
But when the covers are heated, the patterns expand and become protuberant; thus, the covers can preserve our hands from the hot surface
and even scald, as well as increase the friction and make it more stable and safe when using the covers.
