Insulated, Double-walled, Glass Cups Are Best

What is the best cup for a flat white or another espresso-based drink like a latte or a cappuccino? 
 
For me, the answer is easy: an insulated, double-walled, glass cup. Beautiful to the eye and good feeling in the hand.
 
Serve your espresso-based milk drinks in a heavy ceramic mug and your drinks immediately lose heat.
 
For this reason, I use an insulated, double-walled, glass cup that prevents rapid cooling. Another plus, these cups stay cool to the touch even when preheated. I like to fill my cup with water and heat it in the microwave while I grind and tamp the beans.
 
The only downside to these cups is durability. Light glass cups are fragile. I know. I have already broken one. I knocked it over and the inside glass liner shattered. I have heard others complain about the cost but I find stores like Homesense, Marshalls and Winners offer a good selection at excellent prices.
 
Insulated glass cups are practical and good looking. The coffee appears to almost float in clear cup. The espresso and the thin layers of crema and foamed milk are clearly visible. Unlike some plastic mugs, glass cups do not impart off flavours.
 
For me, preheated double-walled glass cups are the best. Love 'em.
