Silt Tea Set by architecture & design studio VW+BS is a stackable tea set made from unglazed purple clay which is meant to soften the taste of whatever drink you put into it. “The unglazed material has the effect of softening the taste of the water in the same way as activated charcoal,” said VW+BS. “This occurs whether you are serving tea, coffee water or wine.” The collection comprises seven items, including a large jug, small jug, bowl and four cups. There’s also a lid that fits any of the pieces. Fifty sets will be made at Taiwanese company Lin’s Ceramics Studio, each with a slightly different finish.
