The vases are made of hand-blown, massive pieces of glass. Their robust design however often seems tender, almost romantic. The vases received the name Papilla due to their round protrusions which are reminiscent of nipples, or papillae in Latin.
Each vase is made from a combination of crystal and stained golden-brown glass which is then glazed with a pastel-blue finish. Achieving the desired shade of blue is not at all easy, as each gram of the added material can change the final outcome.
