Double Walled Martini Glass
Handblown, double-walled glasses made of borosilicate glass combine spectacular optics and extraordinary technical features.
The vacuum between the two glasses prevents the formation of condensate 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. Borosili- cate glass by Zieher stands out due to its hardness and high temperature resistance.
