London designer Mathias Hahn added concrete, brass and metal to these coloured glass vessels, which are inspired by making jam.

Each object in the Preserves collection references a traditional container for storing fruit, Mathias Hahn told Dezeen.

"The large blue bottle, for example, uses a classic cork. However, this cork does not close the bottle itself, but an inner glass cylinder, which stands upside down," he explained.

The vessel with a concrete weight on top makes reference to old containers that were sealed with heavy stones, while the vessel with a metal lid and brass wire around it suggests a swing top for a glass bottle.

The grey glass container is modelled on a preserving jar but has an additional glass container hanging from its lid, while the concave glass on the green vessel references traditional fruit preserves that were sealed with animal skin.

The project is a collaboration with Austrian jam makers Staud's Vienna.

Preserves was presented as part of Passionswege during Vienna Design Week this year, where we also reported on lampshades made from seaweed and a printer that gets its ink from felt tip pens – see all our stories from Vienna Design Week.

Other projects by Hahn we've featured include an oak chair referencing traditional alpine furniture, a set of lamps with hinged wooden arms and a yellow lacquered table, while last year he told us about his work in an interview filmed by Dezeen at imm cologne.

Preserves

An installation of experimental jars

Traditionally we harvest fruit seasonally and start preserving them for the time when no fresh produce is available. Beyond the actual product however, we collect colour, smell and memories of the summer - preserved in a jar. Like treasuring colours of a passing landscape seen from a train window.

Preserves is a series of experimental glass vessels, which portrait the abstract concept of collecting colours. Each one composing an individual chord of shades and referencing a traditional method of preservation.

The materials and colours of the actual vessels resemble shades that are permanent in nature, whereas the content is the precious and fleeting idea of a reflection of summer light.

Preserves is a project in collaboration with premium Austrian jam makers Staud's of Vienna and was presented as part of Passionswege during the Vienna Design Week 2012.
