BLOW is a project inspired by contemporary products that have, for many, unknown production processes. The PET-bottle is taken as an example and its automated production process is re-imagined into a manual one. This allows the creation of new and unique products as well as giving an insight into the production process. Heating a Pre-form (PET tube) and by manually injecting air by pumping, a modern glassblowing is achieved from which these vases are a first design.
