        stone/non-glazed ceramic works ok because it’s porous and absorbs the condensation. These look like glazed ceramic which won’t work well. In high humidity environments there’s so much water the coaster will start to stick to the glass or it’ll spill off onto the surface you are trying to protect, it’s just not ideal.

        Best coasters I’ve found are rubber with a felt/fabric insert. They never move or stick to the glass and the felt has enough surface area to evaporate the water.

            It’s environment dependent. I could use them in the winter when it’s not very warm or humid.

            But in the summer with the windows open a glass of ice water has a ton of condensation around it like the glass is leaking almost. Went through almost all types, plain plastic squares, then to cork, then to stone and finally the felt which actually work.

                Definitely, I’m assuming you drink that hot and hot drinks don’t generate condensation. All you need is a heat barrier and ceramic is great for that no matter what kind of finish it has.
