The glass miniatures from Zieher take coffee service to a new level. The double-walled glass is incredible. 
Mouth-blown and made of borosilicate glass, this glass combines spectacular optics and extraordinary technical features. The vacuum between the two glasses prevents the formation of condensation on the outside of the glass when the ambient temperature is warm and the drinks are cold. The isolation effect keeps cold and warm liquids cold or warm for a longer time. This borosilicate glass by Zieher is temperature resistant between -200° C and +400° C.
Sort of technical stuff that basically says, “Cool For Coffee”.
