They may not look like it now but tiles used to decorate new apartments in a Swansea waterfront development started life as beer and lager bottles.
A student at the city's Metropolitan University is hoping her recycling technique will become a business.
Tyra Oseng won a commission to decorate the show home for new accommodation being built by Gwyr Homes at SA1.
She used empty bottles sourced from a number of pubs, including a campus bar, for raw materials.
The PhD student, originally from Norway, said her sustainable method of production was greener than traditional glass tiles on two fronts.
Not only did it recycle old bottles, but it also used less energy than in hot glass production.
She has created some 'one off' glass kitchen and bathroom tiles and additional decorative glass pieces for other rooms in the Gwyr Homes project, which is owned by the social housing association, Gwalia.
She completed the commission for her PhD research work, but hopes it will develop into a commercial operation - Oseng Glass Design.
She said: "Contemporary and innovative products can be developed in collaboration with architects, interior and industrial designers and artists.
"This has been an amazing opportunity for me to create a bridge between academia and the industry.
"Being able to work with a live case study, meeting the architects criteria and deadlines, has not only given me the most excellent case study but also proven that my work is a potential business."
Jo Margetts of Gwyr Homes said: "Gwalia has always considered the eco-friendliness of its affordable homes and that has been the focus on this current Gwyr Homes development.
"The tiles and other glass features that Tyra has contributed to this show home fit in nicely with the sustainability of the development."
