London Design Festival 2016: London designer Ariane Prin has added to her Rust collection with a series of blue and green-tinged clocks and pots made using copper dust (+ slideshow).

Released as part of the designer's brand Prin, the homeware is made by mixing metal dust with Jesmonite, a gypsum and resin composite material.

Each handmade piece in the collection develops over time as the metal oxidises – causing the colour and texture to change.

As part of London Design Festival, Prin has unveiled several new additions to the collection – which she launched in 2015.

These include larger pots and planters, as well as a set of minimal clocks made from 12 wedges joined together to represent each hour of the day.

While continuing to work with steel and brass, Prin has also experimented with copper, which gives a blue and green tinge to the pieces over time.

The designer collected the metal particles from locksmith and metalworking shops near her studio, in an effort to find a new use for leftover materials.

"Each time I go to my studio I'm excited to see the objects' changing textures," said Prin. "It's like each one of them was alive and slowly mutating with time."

The Rust collection is being shown at Studio1.1 Gallery and at design and electronics exhibition Electro Craft during London Design Festival.

Other homeware highlights of this year's festival include a collection of vessels made from sponge, foam and porcelain; oxidised copper wallpaper; and a circus-themed collection of tableware.
