These colorful bowls are called the Krenit-bowls, designed By mid-century Danish designer Herbert Krenchel in 1953.

From wikipedia: The name Krenit is a combination of the name Krenchel and eternit (a fibre cement which is used for the coating on the bowl’s outside). The bowl has a distinct design with its matt black outside, thin edge and clear colored enamel inside. In 1954, the bowl won a gold medal for its unique design in Triennalen (Milano, Italy). Up until the production stopped in 1966 the bowl had been produced in more than 1 million units.

Although the originals are a highly collectible item, you can still buy these great reproductions at Normann Copenhagen. It might be a last minute notice, but if you want to see them in person, the Rocket Gallery in London is featuring Krenit bowls alongside works by Hans Wegner and Ib Geertsen until April 24th. So you need to hurry!!
