How about a frosted glass?

Glasses are relatively chemically stable and their ingredients do not dissolve when poured into boiling water. However, the inner walls of the frosted surface are not easy to clean. If there is residual dirt, it may cause harm to the human body. So, generally speaking, frosted glasses are made of glass. Also, frosted glass is not polished but chemically cleaned. While we may not feel any odor, it's still not very healthy if you use it to make tea. Therefore, the frosted glass can only be used to drink boiled water and will not cause harm to the human body. Generally speaking, the use of frosted glass needs to be divided according to the situation.
