Double Walled glass insulated tea infuser bottle

The Copenhagen is made out of double walled glass. What makes our bottle superior to others is that our glass is thicker and stronger than other bottles. And more importantly, we heat treat our glass bottles in a process called annealing. In annealing the bottle is heated to high temperatures, and allowed to cool in an oven over time. This releases any stresses in the glass from the bottle making process. The glass becomes more shock resistant.  Although this is still glass and is still breakable, the Copenhagen is the most durable bottle of its kind you can buy.
