Material/component: Glass
● Please avoid usage that causes sudden temperature changes such as rapid cooling or rapid heating. Cannot be used in microwave ovens. ● Do not use metal scrubbers or cleansers as they may cause scratches and chlorine bleach may cause whitish cloudiness. ● If you wash ceramics, metalware, glassware, etc. together in the washing tub, it may cause scratches or damage. ● Storing cups on top of each other may prevent them from coming out or cause damage. ● This glass is soda lime glass. If you leave it for a long time, it may become cloudy, but as a countermeasure, it is effective to soak it in a solution of 3 to 4 times diluted household table vinegar with water for several minutes, and then rinse it with water. (*The alkalinity of soda lime can be resolved by neutralizing it with acid.)
