Watch this: Lost Cardboard Technique

Ray Brown Cardboard Ceramics cups

Artist Ray Brown has developed a creative process called the Lost Cardboard Technique, which turns coffee cup sleeves – those little pieces of card that protect your hands from hot coffee shop cups for about two minutes before they're thrown away – into proper ceramic mugs.

It's an intriguing process and approach to 'opposing the unsustainable culture of waste in which we live', says Brown.

Brown, who studied the craft at London's Metropolitan University, is crowdfunding to buy his own kiln, with pledges starting at £20 for one small, corrugated cup – ideal for an espresso or a nip of whiskey.

Here's the video explaining the Cardboard Ceramics project, itself an example of why art is an important means of tackling sustainability issues.
