After undergoing 1500 dishwasher
cycles, Spiegelau stemware was
certified as "extremely dishwasher safe"
by an independent laboratory. They found
no scratching, markings, loss of brilliance,
foggy shadows, change in color or brilliance or
build up of water chemicals and residue.
Spiegelau's remarkable durability can be attributed in large part
to the Platinum Glass process. As the glass goes from its powder
to its liquid stage, liquid glass is passed through platinum-lined tubes to
eliminate any impurities and remove all imperfections and inconsistencies that
might otherwise exist.
While more expensive, this innovative use of technology proves Spiegelau's commitment to quality.
The result is a "high performance" wine glass with a remarkable marriage of elegance, functionality
and durability.
