The Red Eye Glass 18-inch Colour Changing Beaker is a tall, heavy-duty piece built in thick 7mm borosilicate glass, so it has real weight and stands up to regular use. The glass has a colour-changing effect that reacts to heat and use over time, so the look shifts as you go. The beaker base adds water capacity and a stable footing, and a built-in ice catcher lets you cool the smoke further with a few cubes. At 18 inches it's a sizeable centrepiece. A strong, good-looking full-size beaker for someone who wants durability, a tall pour and a finish that changes over time.
