In the glass industry molds made from steel sheets are usually used only as "optic molds" to create optic difference to the material. From there on the glass forming process typically continues with other tools and molds. 

In Sulava glass design process I focused on the mold and how to take advantage of it's features in a new way. I also wanted to keep the forming process as simple as possible so there is no need for several molds or steps when blowing "Sulava" glass. 

The mold I designed works the same way as normal "optic mold" would, making the optic features of the glass visible but at the same time shapes the glass to it's final form. 

The mold is made from thin laser-cut steel sheets assembled together like a 3D puzzle. It is easy to use and can be operated just by one person.
