U-Type Simple Espresso Cups-QUANSHENG Double-Layer High-Temperature Insulation of High Borosilicate Coffee Cup

You may have seen borosilicate glass in laboratories, as it is chemical and heat resistant. This type of glass is also called medical grade glass. Taking these useful properties of the borosilicate glass into account, glass manufacturers developed the double wall glasses insulated from the very durable borosilicate glass.Double wall glass is relatively new to glassware and barware. For many of us, drinking out of glass is the preferred way to enjoy our favorite beverage rather than drinking out of a plastic cup. Where taste matters for some, for others, the heft of glassware makes a big difference to the drink. Being able to see the content of the tumbler is also an important factor.Double wall glasses are scratch and temperature resistant and can withstand temperature swings that can shatter or crack normal glassware.
Some of the double wall glasses feature a “viscous cooling liquid” in between the walls. This liquid helps to maintain the temperature of the drink in the glass, even when the glass comes in contact with body heat while you hold it. This makes double wall glasses the perfect choice to enjoy an after-dinner espresso or any of your favorite beverages.http://www.amazon.com/gp/product/B074V21TCB
