The Waterford Lismore pattern is a stunning combination of brilliance and clarity. Honour Lismore's Irish roots with a dram from this Tumbler; a 270ml glass that combines the intricate detailing of Lismore's signature diamond and wedge cuts with the comforting weight of Waterford's hand-crafted fine crystal. Enhancing the aesthetics of any drink you serve in it, the Tumbler defines traditional drinkware styling even while transcending it. Combine quarter cup ammonia with a mild lemon detergent. Rinse in clean water and air dry on a rack. Clean vases and decanters by filling them half-full with moderately hot water, a small amount of mild detergent, two tablespoons of white vinegar or ammonia and 1/2 cup uncooked rice. Swirl the rice around for a few minutes to remove residue.
