Unique and distinctive pieces are a hallmark of Lambert. The oak, with its beautiful and sensitive color gradients, embodies this perfectly. The vases are mouth-blown, and the color gradient varies slightly with each individual piece, making each one a true original. Stubborn edges, lime deposits, and plant residues can be removed with vinegar cleaner. Do not wash your vase in the dishwasher, as this may cause what are known as thermal shocks.
