Puzzle Steklarna Hrastnik

Red Dot Award 2016

Red Dot is among the world’s biggest and most prestigious product design contests.

Competing against over 5000 products, the Puzzle glass bowl created by Steklarna Hrastnik has received the Red Dot Award for Product Design. The award serves as further proof of the innovation and expertise that distinguish the employees of Steklarna Hrastnik, as Puzzle bowls – the world’s first 3D stackable glass product – are the result of in-house design, development, and production.


Andrej Božič, General Manager of Steklarna Hrastnik, said of the jury’s decision: “We are proud that the 41-member international jury has given the prestigious Red Dot Award to our Puzzle bowls. We see it as further proof of the quality of our work, innovative ideas of our industrial designers, and technical knowledge of our development and production teams.” Steklarna Hrastnik offers a full range of services – from design, tool development, and production of technically perfect glass products in small or large batches to applying final decorations if requested by the client. Their designers know the ins and outs of the technology and processes involved in creating glass products. This makes it possible for the company to design products that meet the wishes of even the most demanding customers, while also optimising the finished product costs.  

Puzzle – the world’s first 3D stackable glass product
“The Puzzle bowls have come about as a result of an idea I had to combine the aesthetic and useful value of a product in order to create more possibilities for use and take consumers into a new world of creativity and experimenting. It is the diversity of its uses and its excellent 3D modular properties – the possibility of horizontal and vertical stacking – that make Puzzle such a unique product,” said Steklarna Hrastnik’s Grega Likar, the designer of the award-winning product. However, it took something else to bring the world’s first 3D stackable glass product to life: top-level technical production and the hardness of Steklarna Hrastnik glass, which is distinguished by crystal shine and being completely free of heavy metals.
Steklarna Hrastnik is well aware of its social responsibility and the importance of co-existing within the community; with this in mind, they are investing part of the revenue from Puzzle sales in the local community in order to enable students to gain experience and apply their theoretical knowledge in practice.
