A void is made in sand and then filled with molten metal, resulting in a natural overspill that is usually removed in post-production. In the case of 19, the overspill is the highlight of the piece – left raw and oxidized while the centre is polished to a mirror finish. 19 comes in three sizes, each numbered and signed. 19 received a Red Dot Award in 2011.  "21" is composed of thin sheets of porcelain draped around a trumpet shaped borosilicate diffuser. The porcelain is allowed to take whatever form comes naturally, and as such each piece is unique. 21 was a finalist for the D&AD Yellow Pencil Award and was awarded "Best of Year" by Interior Design Magazine in 2008.  "22" is a suite of electrical accessories that eliminate the need for a visible cover plate. Operative components (such as outlets, switches, and ports) are designed to sit flush with any surface they are mounted to. The 22 series won a Red Dot Award, a Yellow Pencil Yearbook Entry and an iF Design Award in 2009. 22 holds US Patent Numbers 7,956,295 and 8,232,482.  "25" is a bench that avoids the traditional upholstery technique of covering foam with fabric, relying rather on excess fabric to provide a comfortable seat. The extra cloth is allowed to fold randomly and changes over time with use. At the time of writing 25 had finished its run and is on indefinite backorder.  "28" is a hand-blown glass pendant with randomly composed interior satellites, one of which acts as a lamp holder. The satellites are created using a technique requiring inversion of the direction of airflow into glass and the subsequent creation of a vacuum, resulting in a controlled implosion. 28s may be suspended by coaxial cable or copper wire in chandelier form or mounted directly to the wall. They come in a multitude of colours and won a Red Dot Award in 2012, an iF Design Award in 2011, and a Good Design Award from the Chicago Athenaeum Museum of Design in 2010. The collection debuted at Spazio Rossana Orlandi in Milan in 2010 and was later exhibited on a much grander scale at the Victoria and Albert Museum in 2013.  "38" is an extreme exploration of the same glass-blowing technique used to create 28. Large glass spheres are filled with random milk-white satellites, some deep enough to house succulents or cacti plants. 38s are suspended with rigid copper tubing.
