The "critical points" rack consists of glass balls, with a non-trivial texture blown into a wooden shape. The balloons are pushed with depressions with wooden rods to fix them in the frame and stability. This rack is an innovative storage system in the house. Glass quality and composition affect the strength and critical points of the glass. It is the strength of the glass and the permissible load that I demonstrate in this project. I work only with natural materials, I also like the fact that I create something that seems easy, but in fact weighs more than 100kg.
