CLOU architects are showcasing a ‘Soft Blob’ made from stretched Mulberry silkworm cocoons at The China Suzhou Design & Cultural Expo.
A lightweight, shell surface is formed by layering sheets of hand-stretched silk cocoons while applying sticky-rice glue as a bonding agent. Using this variation of a traditional fabrication process, the surface of the blob can be seen as a contemporary display of the material’s beauty, while utilizing its exceptional material properties. Thus in this sense, the object can be interpreted as a mysterious creation of ‘incidental nature’.
Often described as a natural ‘metamaterial’, silk fibres are both biodegradable and highly crystalline. Furthermore the material is known for its well-aligned structure, a higher tensile strength than glass fibre, good elasticity and excellent resilience.
Silk fibres from silkworms have been used in textiles for over 5000 years and China has been at the centre of this practice for centuries. This tradition has been documented in The Archives of Suzhou Silk Samples which consists of 302,841 silk samples submitted to the UNESCO Memory of the World Library in 2016.
Silk cocoons made by 2 larvae are called double-cocoons and are used for duvets and pillows fillings in China. Both larvae start spinning the cocoon at the same time, which results in a larger-than-usual cocoon and intertwined filaments. These cocoons are not suitable for unwinding the filaments, however they are perfectly suitable for stretching it into a large batting material to form a quilt. Four workers secure raw dried silk on four sides and stretch it to the desired size of the duvet. In this way the silk is layered until the intended thickness is reached. This technique paired with sticky rice glue lends itself to creating a super thin, lightweight softshell-blob.
“All along we have been calling it a ‘dumb blob’ in order to focus on the essential material qualities and the elementary form we wanted to create,” says Christian Taeubert, Director of CLOU. While on display visitors have imagined the seven and a half meter tall object as a headless duck, a vegetable like a golden or white gourd, something like a pear, or some kind of alien object. The form was abstract enough just to leave enough room for interpretation.
Natural materials as a form of inspiration is not something new to architecture, however the Soft Blob is CLOU’s small contribution to harmonise both the natural and built world. It also serves as a reminder that some of the design problems we face have already been met and solved in nature itself.
Following the exhibition, the Soft Blob has found a new home in Suzhou Art & Design Technology Institute’s permanent collection of their art museum with the intention of being displayed in future exhibitions.
The four day long Suzhou Design & Cultural Expo had received 200.000 visitors this year.
‘为了更好地将设计焦点集中在材质的特性和元素化的空间，我们在设计过程中一直称他为--蠢蠢的团子’ 柯路建筑董事Christian Taeubert说。市民在参观过程中给予了7.5米高的‘软壳’丰富的想象：像没有头的鸭子，像白色的葫芦、梨子，像天外来客。抽象的形体留给大众无限的阐释空间。
